Earlier dynamometer work had identified the percentage of friction and operating temperature of the five main lubricating sites in a reciprocating gas-fueled engine responsible for nearly all efficiency loss. The engine oils of that time were all essentially single grade and carried no SAE “W” classification. However, there’s a lot in addition to oil quality testing that an operator can do to ensure their fryer oil stays fresh as long as possible. This was labeled “air-binding,” since the oil pump became air-bound as the result of a column of oil being pulled from the sump and the oil not filling this void, as shown in Figure 1. Checking car oil is quite easy We recommend that you check the oil level in the morning when the engine Poor-quality engine oils are often put on the market due to ignorance or greed. A new bench test instrument and technique were developed to indicate any tendency of the test oil to gelate. The energy required to overcome this molecule-to-molecule attraction and produce fluid flow can be considered a form of friction. They do, however, come with just an 80% accuracy rate, which is less accurate than TPM methods. This parameter would be near a value of one if phosphorus concentration affected its volatility. It's best to check your oil after your engine has been turned off for at least 10 minutes so the oil can settle at the bottom and cool off. Interestingly, it was later shown that this instrument was unique and basically absolute in providing measures of both shearing torque or shear stress and shear rate while operating. It is normal for an engine to consume a small amount of oil during the engine oil change interval, but it should not be excessive. Otherwise the dipstick will read slightly low. Engine oil is required for its mechanical components to be lubricated and to function properly during operation. Whichever type of pump is fitted, it must be removed from the engine before it can be properly checked. This is where the SAE Rating of any given product comes in. With the exception of 2012, the increase in V-FEI is equivalent to nearly 7 to 8 percent in viscosity-dependent fuel efficiency. Motor oil is the lubricant between the moving engine parts; if the level is too low, the parts will wear quickly and increase likelihood of engine seizure. Check the engine oil level. The oil pump is usually one of three types: the multi-lobe rotor type, the gear type, or the vane type. TPM Measurement: These devices determine the quality of cooking oils by measuring the total polar materials (TPM), or non-triglycerides, based on changes in the dielectric constant, which is measured between two capacitive plates. have become very popular. The PEI data are primarily clustered at values from 2 milligrams per liter to about 30 milligrams per liter. Certain driving habits can affect the life of the oil, as well as driving conditions such as temperature and driving terrain. Viscosity may be defined as a fluid’s resistance to flow. Handheld TPM measuring devices are generally more accurate (usually to within 90%) and remove the subjectivity of the other previously mentioned methods. Handheld and integrated TPM measurement devices are currently available. However, interest among US operators to monitor oil quality is on the rise as operators want to ensure they’re providing a quality experience to their guests. Unfortunately, for the uninformed automobile owner, a high-quality engine oil and one of poor quality will look and feel the same. An old t-shirt usually works great. To be meaningful, the viscosity values had to be obtained at the high shear rates associated with operation in specific sections of the engine. It does tell how these electronic sensors operate. Underhood Service Staff Writers. The data reveals that phosphorus volatility generated by the Selby-Noack test is virtually unrelated to the amount of phosphorus present in the oil as an additive. By. The FFA strips are easy to use and don’t add any interruptions to frying time. The higher the viscosity, the greater the attraction of the oil molecules and the greater the wear protection. API’s Engine Oil Licensing and Certification System (EOLCS) is a voluntary licensing and certification program that authorizes engine oil marketers that meet specified requirements to use the API Engine Oil Quality Marks. Today, the grades are set for engine operating temperatures and for winter temperatures at which the oil affects starting and pumping. The technique was accepted by ASTM as test method D4683 for use at 150 degrees C (and more recently as D6616 for use at 100 degrees C). They also work for any oil type (vegetable, animal, or vegetable/animal blend). See how easy it is to test your own engine oil, and save money with extended oil changes. Therefore, careful formulation of the oil viscosity is critical to vehicle owners and to governments mandating fuel economy limits. This is what happens when a timing chain or belt breaks. Start by consulting your owner's manual. In short, it helps you know when engine oil needs to be changed. In the early 1980s, an instrument and a technique were developed that could reach several million reciprocal seconds at 150 degrees C as well as exert high shear rates at other temperatures on both fresh and used engine oils. With the oil color guide tubes, the major advantage is cost. Now, pull it out and be ready with old fabric or rag to wipe and clean the dirt off of the dipstick. Finally, make sure all staff is trained on proper frying techniques, fryer usage and care. Do not fill up over the maximum level. Engine oils were collected directly from the market and analyzed by selected laboratories through a series of bench tests. This is a significant amount of energy from the engine in exchange for the provided wear protection. Engine Timing Chain Wear: Why Oil Quality Matters. Turn off the engine. A decade ago, the lowest SAE viscosity grades were SAE 0W-20 and 5W-20 oils, with SAE 20 carrying the minimum high shear rate viscosity of 2.6 centipoise (cP) to simulate engine operation at 150 degrees C. Figure 2 shows data from engine oils sold in North and South America as well as for SAE 5W-30 engine oils. These engine oils are likely to be more harmful to the exhaust catalyst. It collected the volatile component of the volatility test for further analysis, which was helpful in detecting phosphorus and sulfur. This same molecular friction prevents the oil from escaping too quickly when two engine surfaces in relative motion are brought closely together under pressure. Your email address will not be published. This ultimately led to restrictions on the quantity of these chemicals in engine oil and fuel. If you really need to check the condition then you have to take a sample and send it to a lab. It is best to check the oil in the morning before the car has run, as all of the oil will have run back down into the oil pan. A first quality synthetic engine oil; Works well in all weather conditions; Can be used on Sprinter vehicle models; Cons: May not be suitable for some engines which may require different oil viscosities, check instructions. Warning: Never check the oil when the engine is hot. The Ford IOLM system is not just a simple oil quality sensor, but a software based, algorithm-driven device that takes into account various operating conditions of the engine to determine when the oil needs changing. Your car's handbook will list the specification(s) and grades of engine oil that are suitable for your car. The market value of an individual crude stream reflects its quality characteristics. Once you have allowed the engine to run for a couple of minutes, allowing the oil to circulate, turn off the engine and allow it to cool for about 5 minutes or so. It is evident that considerable progress has been made in reducing the phosphorus decomposition and/or volatility of these two multigrade SAE classifications. Required fields are marked *. In addition, antioxidants help prevent the oil from breaking down and clogging the engine with sludge and deposits. Figure 4 shows the response of two of the most volatile multigrade engine oil classifications. Pull Dipstick And Clea n. The first step would be to locate the dipstick in your vehicle. Fortunately, once the quality level has been determined on the dynamometer or in the field, there is a much less expensive approach that can be applied to more precisely appraise the oil quality. Soluble phosphorus compounds such as zinc dialkyldithiophosphate (ZDDP) have been used in formulating engine oils for many years. It’s about finding the right method that works for you and your staff. Which engine oil does my car need? It is the only known viscometer capable of doing this. Each model vehicle may have a different oil capacity. What are today’s most common testing methods and what exactly do they test for? Our own Kimberly Eros, answered some questions on the different methods of oil quality testing and how your restaurant can use them to your benefit. Best high performance synthetic oil. I think 10,000 kms is the sweet spot. The cooling cycle had produced a condition in which the oil became air-bound. on. The oil drain intervals, to be effective, must be determined by oil analysis. This article will show you how to check your engine oil consumption properly. to check the engine oil, first locate the engine oil dip stick on the side of the engine (figure no 1). Also, check the oil’s color. Interestingly, over the last several years, there has been an increase in the number of automobiles operating with engine oils that have lower viscosity levels, thus markedly improving their engine efficiencies. First, check the owner's manual and follow the automaker's recommendations. Since viscosity is directly related to the amount of energy expended by the engine for wear protection through hydrodynamic lubrication, such a decrease in viscosity would be expected to have important benefits in fuel efficiency but only in engines designed for their use. While most engine oils are made to acceptable standards, their general and specific qualities can vary widely. Low oil pressure - indicated on the oil-pressure gauge or dashboard warning light - could provide an indication of wear or damage to the pump. The costly incident revealed the need for a more sensitive bench test that would accurately predict the tendency of air-binding pumpability failures. This training will ensure the consistent delivery of high-quality fried foods for your guests and allow for maximum oil usage, which lowers operating costs. Scientifically speaking, fresh cooking oils are naturally non-polar and almost pure triglyceride, meaning their compounds are symmetrically shaped and not “broken-down.” During the frying process, air, moisture and heat are introduced to the oil. In order to run properly, a car needs oil. Not all vehicles take 5 quarts of engine oil. Name *. To find out whether your vehicle needs oil, follow these steps: Pull out the dip stick and wipe it off on a clean, lint-free rag. The air-binding engine oil that caused the Sioux Falls failures provided a solid case study. The Selby-Noack volatility test was developed in the early 1990s as a better and safer approach for determining engine oil volatility. Judging engine oil colour is a waste of time. This important benefit was immediately apparent, and multigrade oils have since become the most popular form of engine lubricant around the world. It should contain information on how to check the oil in your vehicle. Pop the hood, pull the oil dipstick out, wipe it off, reinsert it … This was a considerably more serious issue, as lack of oil pumpability could destroy the engine. Checking and changing your car's oil at regular intervals is important for the health of the engine, to ensure your car is running efficiently. High levels of oil consumption may be indicative of a leak or some internal engine wear. Read More » HEAVY DUTY DIESEL ENGINE OIL PETROLEUM QUALITY INSTITUTE OF AMERICA SAMPLE SUMMARY/HEAVY DUTY DIESEL ENGINE OIL Heavy duty diesel engine oils are formulated to meet … The dipstick is connected to the oil tank in your engine, and is used to determine how much oil is still in the oil tank. Manufacturers recommend monthly calibrations, a 10+ minute, multi-step procedure, as well as annual testing, which requires shipment to the manufacturer. Engine Oil, Check! You should check your oil levels when your engine is cold. Jan 5, 2017. The smaller the number, the better it will flow. Figure 5 shows the change in PEI over the last eight years. There are several different methods used to measure oil quality ranging from subjective visual inspection to more objective, scientific measurements. Follow these simple steps to check your vehicle’s engine oil: 1. Consumer Reports suggests that drivers check their oil at every other gas fill-up. Manufacturers recommend changing your engine oil every 12 months or 9,000 miles, whichever comes sooner, but you should still check your engine oil at regular intervals to ensure your car remains safe to drive. But as the old Castrol ad used to say “oils ain’t oils”, so it pays to know which is right for your car whenever the dipstick shows a low oil … The second was less obvious and involved the gelling of the oil under a long, deep cooling cycle. However, they were no longer Newtonian in flow characteristics, as the viscosity was found to decrease with increasing shear rate. In worse cases, the check engine … Lowering oil viscosity can be an important step in reducing viscous friction to improve fuel efficiency. How much influence the phosphorus in an engine oil has on the amount of phosphorus volatilized during engine operation is an important question affecting the choice of additives in oil formulation. It goes without saying that the higher quality of oil you choose, the more expensive it’ll be. It should appear brown or black. Unburned or partially burned hydrocarbons from the engine exhaust were modified by sunlight into noxious gaseous hydrocarbons, which produced smog in some large cities. The quality of oil is key to a smooth, efficient & powerful engine. For example, my 4.3 L engine in my blazer takes 4 1/2 quarts of oil. It is in the sump and contains 3 separate sensors - one for level, one for oil quality, one for temperature. Is any one of these methods preferred or recommended over the others? If the engine oil level is above the High/Max mark, you should remove oil from the engine to avoid damage to your car. This inability of the intervening oil to escape quickly and its level of incompressibility hold the two surfaces apart and prevent wear, a process that is termed hydrodynamic lubrication. Measuring total polar materials (TPM) and free fatty acid values (FFA) are the most predominate indicators for oil quality and are widely used in many international markets where oil quality is strictly regulated. In case of use for work, we recommend that you check your oil level daily. But if it has a light, milky appearance, this could mean coolant is leaking into the engine. To serve the engine, oil must possess certain physical and chemical properties. Figure 3 shows the average value of SAE 0W-20 and 5W-30 engine oils from the North and South American markets from 2008 to 2014. The location of the oil … SAE stands for the Society of Automotive Engineers. These bench tests have the capability of providing a relatively inexpensive measure of oil quality. Even as engine design has changed to meet performance, fuel efficiency and environmental standards, the engine continues to be the ultimate arbiter of oil quality. You need to check motor oil before any long trip to avoid major damage. Volatized oil reduces the amount of lubricant serving the engine and may carry exhaust catalyst-contaminating components, negatively affecting the catalyst’s smog-reducing ability. Then, pop the hood and locate the dipstick, which is a long rod with a ring on the end of it that's usually found near the front of the engine block. This determination can only be made by using the oil or pre-testing it. Don’t worry, you’re not alone. However, the value and significance of this type of test is dependent on a number of factors, including identification of the engine’s specific needs, clear and consistent information from the engine either in dynamometer tests or field experience, and an understanding of the relationship between the engine’s needs and the oil’s physical and/or chemical properties. Romantic Valentine Day Gifts for Wife Shannon Fagan/ Getty Images One of the worst pieces of news you can ever receive as a car owner is to hear that your engine is toast -- so worn down that your only options are to replace it or buy a new car . Japanese automakers have recently called for even lower viscosity grades. The engine oil consumption should be checked regularly. Dipstick or not. After your quick oil change service is completed, One of the first things that you want to check is that the oil is filled to its proper level. The database, which is available at www.instituteofmaterials.com, now covers more than 14,000 engine oils worldwide. Some newer cars have electronic oil monitors and don't have traditional dipsticks for manual inspection. Since that time, multigrade oils (e.g., SAE 10W-40, 5W-30, 0W-20, etc.) A first quality synthetic engine oil; Works well in all weather conditions; Can be used on Sprinter vehicle models; Cons: May not be suitable for some engines which may require different oil viscosities, check instructions. Your car may not have a dipstick – some modern vehicles are fitted with electronic oil monitors. With easier engine startability at low temperatures, another problem became evident - oil pumpability. Such debris can restrict or block critical oil passages causing a loss of oil pressure or engine damage. In between your regularly scheduled oil changes, you can check your engine oil levels to ensure that it has not become too low or dirty. If the engine oil is low, it could indicate the engine is either leaking or consuming oil. For diesel engines, the current top oil rating is CI-4. I stick to 10,000 kms for a synthetic oil change on my cars. The decrease shown in the average fuel efficiency of SAE 0W-20 engine oils collected in 2012 may indicate the development of formulations meeting automakers’ concerns that the benefits of hydrodynamic lubrication will not be lost in efforts to improve fuel efficiency. If it has a burnt odor: then it's time to change the oil. How to check your oil. Next, check the oil level via the dipstick. A lighter, milky color could mean that coolant is leaking into the oil. Once your car is parked on level ground and the engine is off, Consumer Reports recommends these steps for checking your oil: Pop the hood. Official Lubricheck Oil Tester demo. Regular filtration, proper cleaning and timely maintenance are key to avoiding build-up, which accelerates oil degradation. With so many options for motor oil, it can be overwhelming finding the perfect option for your vehicle. Reinsert the dipstick, pull it out and check the oil. With the trend toward smaller, fuel-efficient and turbocharger-equipped engines generating higher temperatures during operation, a bench test that can reveal an oil formulation’s phosphorus emission tendencies would be useful in designing lubricants best suited to the engine and the environment. The dipstick is often located near the front of the engine. Are there any other best practices for these testing methods operators should be aware of? Note that most Jeep have an oil pressure gauge next to the speedometer - this gauge does not tell you what your oil level is, however the video above will show you how check the oil level in your 2014 Jeep Cherokee. Minimum limits were then imposed for various grades in the SAE viscosity … The most obvious alert that there’s an issue with your oil will come from the car itself. Each model vehicle may have a different oil capacity. In the last few years, it is evident that the SAE 0W-20 and 5W-30 classification categories were designed to meet the ILSAC volatility specification by a comfortable margin. Over a 24-hour period, a number of engines containing oil were ruined. Oil is the lifeblood of your vehicle's engine. When the car is in motion the oil splashes around and covers the entire stick. For more answers to your questions regarding oil quality testing or any other technical question about your Henny Penny equipment, visit Henny Penny’s Technical Support site or contact the 24-hour technical support center at 1-800-417-8405. As engine design has progressively increased power from smaller engines, the difficulty of establishing repeatable dynamometer tests has grown even more rapidly. None of these lower grade oils has yet to reach the market for analysis. Finally, the measurement procedure is time-consuming, which can interfere with labor, and is dependent on proper operation. Unfortunately, in the years following the catalytic converter’s development, it was discovered that certain elements in gasoline or engine oil, including phosphorus and sulfur, would deactivate the catalyst by coating it. The Engine Light is On. According to a recent study by ExxonMobil, a shocking 50 percent of drivers in the U.K. don’t know why engine oil is needed, while 75 percent don’t know HOW to check their oil. As a consequence, exhaust catalytic converters were developed in the 1970s to treat the exhaust gas and convert it into carbon dioxide and water. Most people overlook checking engine oil. You should check your oil levels when your engine is cold. A lubricant’s viscosity has always been associated with wear protection. Thirty years ago, based on concerns expressed by engine manufacturers about the quality of some oils, the Institute of Materials (IOM) began to compile an engine oil database. However, using the engine to measure oil quality in dynamometer tests can be an expensive proposition. To check your oil level you need to start with a clean stick. It should not smell burnt or be milky, clumpy or discolored, all of which are signs of potential engine problems. Of all the engine oil’s physical and chemical qualities, its viscosity and viscometric behavior during use are often considered the most important. Consider … In the API's words, SM oils are \"designed to provide improved oxidation resistance, improved deposit protection, better wear protection, and better low-temperature performance over the life of the oil\" [source: API]. Two of the most important quality characteristics are density and sulfur content. This way, if there is something wrong you could spot it at an early stage. The API's current highest rating for motor oil is SM. Monitoring an operation’s oil quality is always a good thing as it helps ensure tasty, quality fried foods for your guests. Your email address will not be published. Shell Rotella (550019921) T6 5W-40 Full Synthetic, Heavy Duty Diesel Engine Oil (CJ-4) The process for how to check your oil is simple and involves using the dip stick to see levels and test quality. These are some of the methods they’re using today: The darker color in the Oil Color Guide Test Kit represents an oil color that’s reached the end of its useful life when frying proteins.
