An API service rating of "SF" means the oil meets all new car warranty requirements for 1981 and newer models. "SE" means the oil is usable in all 1972-1980 vehicles. "SD" means the oil is good for all 1968-1971 cars. "SC" is adequate for all 1964-1967 models.
What does SE and SF mean in motor oil?
What does the se or sf stand for in motor oil? These are service rating codes to tell you what year vehicle they can be used in. However both SE & SF are obsolete oils that you should not use in any vehicle. SE was a classification used from 1971-79 and SF was used from 1979-88. What type of oil is used in the transmission of 1987 Yamaha yz 80?
What does SJ mean in engine oil?
What is SJ or later oil? This oil is intended for all gasoline engines currently in use and has been the standard since 2004. ... And category SJ protects all gasoline engines from 2001 (and earlier), so everything below the grade of SJ is considered obsolete. What is the difference between SN and SJ oil?
What does the letter S mean in engine oil?
Category S is for “Spark Ignition”, for Gasoline and category C is for “Compression Ignition’, for Diesel. For both, the letter S or C is followed by another letter. For example, SM or CF. The higher the letter, the more recent the technology of the oil. For recent oil, the higher specification will supersede the lower letter grade.
Can I use SJ oil instead of SH?
API SJ oils can be used in any applications where SH oils were being appropriately used. So if your owner's manual calls for an API SE, SF, SG or SH motor oil - API SJ will work just fine. What does 10W 30 SJ mean? This means the viscosity is at 10W when the engine is cold and 30 when the engine is hot.
What does SF or SG mean with motor oil?
(WARNING: Lubricants in these classifications may cause damage to modern engines) SE - Obsolete, not suitable for engines built after 1979. SF - Obsolete, not suitable for engines built after 1988. SG -Obsolete, not suitable for engines built after 1993. SH - Obsolete, not suitable for engines built after 1996.
What is CF and SF engine oil?
The first part, SJ, is a petrol engine oil rating, with the S representing petrol engine and J representing the performance level or additive package type. The second part,CF, is a diesel engine oil rating, 'C' being diesel and 'F' being the performance level.
What is SAE 30 SF oil?

What is SF 15w40?
MOTOR OIL SF 15W-40 is a multi functional mineral engine oil for older gasoline-, diesel- and LGP engines of passenger car and light vans with or without turbo compressor. MOTOR OIL SF 15W-40 is not suited for engines equipped with a Diesel Particle Filter (DPF).
Is SN oil better than SF?
The “S” category designates oils for gasoline passenger car engines, and the “C” category designates oils for diesel-powered commercial truck engines. The “S” series is composed of SA, SB, SC, SD, SE, SF, SG, SH, SJ, SL, SM and SN. SN oils provide higher levels of performance than all the other “S” oils.
What is API SF CD?
Mineral engine oil SAE 40 API CD/SF. The oil is intended for the use in diesel engines of heavy vehicles with supercharging, operating under maximum load. It is also possible to use it in the diesel engines of motor cars and trucks, and naturally aspirated gasoline engines.
Can I use SAE 30 instead of 10w30?
The winner of best oil between SAE 30 vs 10w30 needs to be chosen with operating conditions in mind. Basically, SAE 30 works great in older mowers, but most newer mowers call for 10w30. SAE 30 is also better in warm conditions while 10w30 can accommodate colder ones as well.
Can I use 5w30 instead of SAE 30 in my lawn mower?
In most cases with a lawn mower engine, you'll be fine using SAE 30 vs 5w30.
Can I use 10w40 instead of SAE 30?
However, in general, I probably wouldn't recommend using 10w40 instead of SAE 30 in your lawn mower. What is this? Most lawn mower engines are designed to use oil with a viscosity rating of 30. Because 10w40 has a higher viscosity, your engine might not be able to lubricate itself as easily.
What is the difference between SE and SAE oil?
SAE is the Society of Automotive Engineers. They're the group who sets the viscosity standard, not an actual standard. The API service level is in the top half of the "donut" seal. SE and SF are old standards that have been replaced.
Can I use 15w40 oil in my bike?
no. You should not us truck oils in your bike, especially something like an R1. If you"re going to run the bike hard and hot for long stretches, like on a track, then you need to use something equivalent to Motul 15w40 (or even 15w50) that has been specially formulated for bikes.
What is the meaning of SN CF?
abbreviation for. Société Nationale des Chemins de Fer: the French national railway system.
What is SA and SB oil?
An "SB" rating means the oil affords only minimal protection, and "SA" is pure mineral oil that should be avoided. Today's new cars, obviously, require engine oils with an "SF" designation, either alone or with a lower rating such as an "SE." Any oil without an "SF" could cause engine damage and void the warranty.
What is CC grade oil?
CC — Diesel Engine Service Oils designed for this service provide protection from high-temperature deposits and bearing corrosion in these diesel engines and also from rust, corrosion and low-temperature deposits in gasoline engines. These oils were introduced in 1961.
What does SB mean in motor oil?
SB. Obsolete. CAUTION: Not suitable for use in most gasoline-powered automotive engines built after 1951. Use in more modern engines may cause unsatisfactory performance or equipment harm. SA.
What is SE and SF?
SE and SF are old standards that have been replaced. http://www.pqiamerica.com/apiserviceclass.htm You probably won't have much luck finding them in the US anymore. The newer standards are designed for better gas mileage (which also makes them less desirable for use in a shared-sump motorcycle engine). They're currently on SN.
What does "cold" mean in oil?
Cold is not inclusive to mean cold outside. It means a cold engine start. It could be 70F outside but to the engine, it is a COLD start. Those friction modifiers may make that oil behave "thinner" at colder abient temps (32F and below) and it will flow better under those demands but what happenes when the oil reaches full temp?
What is SAE in automotive?
SAE is the Society of Automotive Engineers. They're the group who sets the viscosity standard, not an actual standard. The API service level is in the top half of the "donut" seal.
How long can you run oil on a bike?
No offense..... but you can run the oil of your choosing, whatever it may be, in your bike for 7,000 miles. ... and then change it, and before you even start it back up... the fresh oil will be black in the window...
Why is multi weight oil important?
The rate of engine wear is highest at start up. Oil must be thin enough to flow freely and provide lubrication when the engine is cold but not get too thin when the engine gets hot. This is why multi-weight oil exists. It is important not to use too high a weight oil in cold temperatures.
Which has less modifiers, 10W-40 or 5W-40?
Very correct in that a 10W-40 uses less modifiers than a 5W-40....
Is GTX oil synthetic?
This is why I think synthetic is better in a motorcycle. GTX is not synthetic. Synthetic does not use viscosity modifiers to the same extent as regular oil. From what I have read the viscosity modifiers break down causing the loss in viscosity at operating temperatures, not the base oil.
What does the W suffix mean in oil?
A number without a W suffix indicates the oil thickness was measured when the oil was hot (210 degrees F). Two numbers separated by a hyphen indicate a multiviscosity oil.
When did oil become SJ?
For the time period of October 15, 1996 to August 1, 1997, oils can be labeled SJ OR SH, but not both. After August 1, 1997 only the SJ designation will be allowed. The major differences between SJ and SH are: - Reduced phosphorus levels are required to meet SJ criteria.
What does the C stand for in a gas engine?
The "C" stands for compression ignition - oil fueled (diesel) engines. The second letter of the pair denotes the quality rating. At this time a high quality rating for an oil is designated by the letter F or G.
What is the SAE number for oil?
SAE numbers include, for example, 10W-30, 5W-40 and sometimes just a single number such as 5W, 10W, 20, 30, 40 or 50.
What does a hyphen mean in a multiviscosity oil?
Two numbers separated by a hyphen indicate a multiviscosity oil. Multiviscosity oils are tested at both hot and cold temperatures and are recommended for all-season use. Multiviscosity oils are able to lubricate moving parts over a wide range of temperatures.
Can you make SAE 40 oil with 10W-40?
A multiviscosity oil such as a 10W-40 will function like an SAE 10W oil at cold temperatures and like an SAE 40 oil when the temperatures are warm or hot. Note that a multiviscosity oil can not be made by combining individual SAE oil viscosities together.
What does SA to SH mean?
Diesel. Specifications from SA to SH are considered obsolete, meaning that you cannot get any official license from the API. It is meant for 1995 and older engines. As explained earlier, the higher the letter, the more recent and a higher specification would supersede the lower ones.
What is API oil?
The American Petroleum Institute, API, is a U.S.A trade association for the oil and natural gas industry. It reunites different actors in the production, refinement, distribution and many other activities around ptroleum. Amongst their activities, they set up diverse technical standards, such as measurement methods, standards for the design of pressure vessels, etc., but also industry standard for the energy conservation of the motor oil.There are two categories: gasoline and diesel. Category S is for “Spark Ignition”, for Gasoline and category C is for “Compression Ignition’, for Diesel. For both, the letter S or C is followed by another letter. For example, SM or CF. The higher the letter, the more recent the technology of the oil. For recent oil, the higher specification will supersede the lower letter grade. For example, if we have an oil with specification SN, it can also be used for vehicles which request API SM, SL and SJ; it is backward compatible.
What is the suffix for oil grades?
The Society of Automotive Engineers (SAE) defines a numerical system for grading motor oils according to viscosity. The suffixes (0, 5, 10, 15 and 25) followed by the letter W designate the engine oil's "winter" grade.
What is service rating in oil?
The program certifies that engine oil meets certain Original Equipment Manufacturer (OEM) quality and performance standards. The service rating is shown in the API "Service Symbol Donut" on the product label. As shown in the illustration below, engine oils with an API SA Service Classification were formulated for use in cars built prior to 1930, and are now obsolete. Yet, there are still not hard to find in retail outlets. Read on about what you need to read on the labels.
What is OEM specific performance?
Although the majority of vehicles currently on the road in the US specific the use of motor oils meeting a specific API Service Category, some vehicle manufacturers require use of lubricants that meet the original equipment manufacturer's (OEM) specifications.
What is the viscosity grade of oil?
Look to your owner's manual. It specifies the viscosity grade required for your car's engine. Today, the most common grades are 5W-30. Whereas the labeling on the bottle of engine oil may suggest the product is a 5W-30, note, if there is no "W" between the 5 and the 30 it may not be a 5W-30.
