As explained earlier, the higher the letter, the more recent and a higher specification would supersede the lower ones. API SN to SJ are for the most recent cars, API SH to SA for the older cars. In this case, you need API SL, so an API SJ, lower, cannot be good. SM and SN supersedes SL so both oils can be used.

Besides, what does API service SJ mean?

The first letter, S, indicates the oil is for gasoline engines. The codes are as follows: • SN: For vehicles manufactured after 2010. • SM: Vehicles manufactured between 2002-2009. • SJ: Vehicles manufactured before 2001.

Subsequently, question is, what is the difference between API SM and API SN? In 2010 the American Petroleum Institute introduced a new engine oil category under the name API SN and a new supplemental category called Resource Conserving. The API SN category is an improvement over the API SM category in the following areas: High temperature deposit protection for pistons.

Keeping this in consideration, is API SN oil synthetic?

Yes! The following Quaker State products are all licensed by the American Petroleum Institute as complying with the specifications of the new API SN PLUS category: Quaker State Ultimate Durability Full Synthetic Motor Oils - SAE 0W-20, SAE 5W-20, SAE 5W-30 and SAE 10W-30.

What is API SN in engine oil?

API SN PLUS is a new motor oil specification developed for turbocharged engines that is being developed in response to automakers request for motor oils that protect against Low-Speed Pre-Ignition (LSPI).

What is 5w30 SN?

In a 5W-30 for example, the number before the W describes the viscosity of the oil at low temperatures. The lower the number, the thinner the oil and the better the oil's cold temperature/ cold start performance. The number after the W describes how thick the oil is at the engine's normal operating temperature.

Can I use SN oil instead of SF?

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. However, you have to pay attention to the year of construction of the engine.

What is SN oil rating?

SN Rated Motor Oils
The latest service category rating for gasoline engines starting in 2011 model year cars and light trucks is "SN." The API SN rating is equivalent to the new GF-5 oil rating by the International Lubricant Standardization and Approval Committee (ILSAC).

Is Mobil One Dexos approved?

Everything else is Dexos equivalent. Mobil 1 is Dexos qualified, however, that doesn't mean the Dexos Specification is up to the level of Mobil 1.

Can I use SN oil instead of SG?

The current specification is API "SN", introduced in October 2010 for 2011 and newer vehicles (although they can be used in older vehicles as well). Furthermore, although the API does not issue the same cautions for SF, SG, and SH, they make it clear these motor oils are also "obsolete."

What does the W mean in oil?

The "w" in motor oil stands for winter. The first number in the oil classification refers to a cold weather viscosity. The lower this number is, the less viscous your oil will be at low temperatures. For example, a 5W- motor oil will flow better at lower temperatures than a 15W- motor oil.

What is the highest API rating for oil?

These identify that the oil meets the API's service standards, and will help keep you away from the lower quality oils. The API's current highest rating for motor oil is SM. This oil is intended for all gasoline engines currently in use and has been the standard since 2004.

What is API service rating?

The service rating of passenger car and commercial automotive motor oils is classified by the American Petroleum Institute (API). The program certifies that an oil meets certain Original Equipment Manufacturer (OEM) quality and performance standards. It specifies the viscosity grade required for your car's engine.

Is SAE 5w 20 synthetic or conventional?

Most carmakers are now suggesting 5W-20 or 5W-30. Conventional motor oil works very well and with regular changes there is no reason that an engine won't achieve 200,000 miles. Many carmakers are now calling for full synthetic oil in their high-tech engines.

Does it matter what 5w30 oil I use?

If your car takes 5w30 oil and you put 5w30 oil in it, it'll be fine. Totally wrong, these days the spec compliance of an oil is often more important than the viscosity. Don't put any 5w30 in, put the correct 5w30 in.

Can you use regular oil after synthetic?

When changing from synthetic to regular oil, there is not anything special that you need to do because synthetic oil will mix directly with regular oil of the same weight (no engine flush is needed). Synthetic and conventional oils are compatible, so it is not harmful if you decide to switch."

Can you mix synthetic oil with regular oil?

The simple answer: Yes. There is no danger mixing synthetic and conventional motor oil; however, conventional oil will detract from the superior performance of synthetic oil and reduce its benefits. So, yes, you can safely mix synthetic and conventional oil.

Is SAE 5w30 synthetic oil?

The petroleum base oil alone may have the properties of an SAE 5 grade oil. This means at extremely low temperatures, it may be thick, and at high temperatures, it's fairly thin. When it's brand new, a 5W-30 conventional motor oil acts exactly like a 5W-30 synthetic motor oil.

Is synthetic blend oil better?

Because synthetic oil is better on your engine and has fewer impurities, it can go longer than conventional oils or synthetic blends. Turbo engines and older cars may still require oil changes every 3,000 to 5,000 miles. Synthetic oil change intervals range 10,000-15,000 miles or once a year (whatever comes first).

What is 5w30 oil used for?

Uses of 5w30
5w30 is used in light-duty diesel engines, light-duty petrol engines, and automotive gasoline engines. 5w30 engine oil is preferred for engines working in cold climates, as it gives good flow at lower temperatures.

What is Dexos oil?

Dexos engine oil specification is designed by GM Powertrain engineers and is intended specifically for GM engines. Dexos is designed to increase fuel efficiency, extend the life of the vehicles emissions system, reduce oil changes and extend the life of the vehicle.

Can I use gasoline oil in my diesel engine?

It's common for today's diesel engine oils to carry both the API CK-4 and API SN specifications. If the diesel oil carries both specs, the oil is safe to use in diesel and gasoline applications. If the diesel oil does not carry the “S” category, AMSOIL strongly recommends against using it in gasoline applications.
