What is the difference between Ilsac and API?

ILSAC GF-6 applies to the fuel efficient viscosity grades, while API SP applies to those heavier viscosity grades like 10W40 and 20W50. API SP will be fully backward-compatible with previous API service categories, including API SN PLUS, SN, SM, SL or SJ.

What kind of oil is Ilsac GF 5?

Oils meeting ILSAC GF-5 are typically low HTHS (≤ 3.5cP) SAE 10W-30, 5W-30, 0W-30, 5W-20, 0W-20 and 0W-16 based on API Group II, Group III or Group IV base oils and coupled with API SN PLUS, API SN and resource conserving claim. For more information on ILSAC GF-5, contact your Lubrizol representative.

Is 5W or 10W better?

A 10W oil thickens more than a 5W. The other number indicates the oil’s resistance to thinning at high temperatures. Amsoil claims that it withstands the stress and high-running temperatures while lubricating the performance parts to avoid sludge buildup.

What does API SN mean?

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. Better sludge control.

Is Ilsac GF-5 oil synthetic?

Eneos (3230300) API SN/ILSAC GF-5 Certified 0W-20 Fully Synthetic Motor Oil – 1 Quart Bottle.

Can I use API SN instead of SM?

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.

Is Ilsac GF-5 synthetic oil?

What does Ilsac GF-5 mean?

ILSAC GF-5 defines the performance requirements for engine oils for use in 2011 model-year vehicles. Development of ILSAC GF-5 targeted three key performance improvements relative to ILSAC GF-4: (1) improved fuel economy; (2) improved engine oil robustness, in particular piston cleanliness and engine sludge protection; …

Does 10w30 hurt 5W-30 engine?

Most oils will mix perfectly, provided they have a similar synthetic. Therefore, there is no problem in mixing 10w30 and 5w30 since one will be topping up. Mixing the viscosity of oils will not have any effect on the engine. 5w30 and 10w30 engine oils have close viscosity, and thus there is no harm in mixing them.

Which oil is heavier 5W or 10W?

A 10w-40 motor oil is a thicker oil at startup than a 5w-30 motor oil. Therefore, 10w-40 oil clings to the engine’s moving parts more than the lower viscosity 5w-30 oil.

Does SN on oil mean synthetic?

sn= synthetic oil. Most likely ‘sn’ stands for synthetic oil… which this oil IS & meets synthetic oil requirements and standards.

What does sn mean for engine oil?

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.

What are the requirements for the ILSAC GF-5?

ILSAC GF-5 REQUIREMENTS. 1. FRESH OIL VISCOSITY REQUIREMENTS. 1.a SAE J300 Oils shall meet all of the requirements of SAE J300. Viscosity grades are limited to SAE 0W, 5W, and 10W SAE 0W-20, 5W-20, 0W-30, 5W-30 and 10W-30 multigrade oils.

What is the ILSAC standard for engine oil?

ILSAC STANDARD FOR PASSENGER CAR ENGINE OILS NAME STATUS SERVICE GF-5 CURRENTIntroduced in October 2010 for 2011 and older vehicles, designed to provide improved high temperature deposit protection for pistons and turbochargers, more stringent sludge control, improved fuel economy,

What makes an API SN a supplemental category?

The former supplemental category, which was called Energy Conserving required only fuel saving properties from the oil. Resource Conserving requires further properties like: The requirements of API SN with the Resource Conserving supplemental category are identical to the requirements of the ILSAC GF-5 standard.

Which is better API SM or API SN oil?

The API SN category is an improvement over the API SM category in the following areas: 1 High temperature deposit protection for pistons 2 Better sludge control 3 Better seal compatibility 4 Aftertreatment compatibility
