What does SG SH mean in oil?
The current standard is backservicable to these standards. SG = Service typical of gasoline engines in passenger cars, vans, and light trucks beginning with the 1989 model year. SH = 1994 provides improved control of engine deposits, oxidation and engine wear relative to oils developed for previous categories.
What does API SJ mean on oil?
API Service Category SJ was first introduced in 1996 for use in gasoline engines and is not suitable for use in engines introduced after 2001. API SJ oils are typically high HTHS (≥ 3.5cP) SAE 10W-40, 15W-40 and 20W-50 based on API Group I or Group II base oils.
Is API sp better than API SJ?
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.
What is API oil 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 an oil higher than SJ?
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.
Can I use SN oil instead of SJ?
What oil is higher than SJ?
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.

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.
When should API service category SJ oil be used?
They may be used where API Service Category SJ and earlier categories are recommended. Category SJ was adopted in 1996 to describe engine oil first mandated in 1997. It is for use in service typical of gasoline engines in present and earlier passenger cars, vans, and light trucks operating under manufacturers recommended maintenance procedures.
What is the difference between API Service classifications SH and SJ?
Oils meeting API Service Classification SH may be used to replace SG, SG/CC, SF, SF/CC and SE are recommended. (obsolete) S J = 1997 SJ may be used where API Service Classifications SH and earlier have been recommended. S L = 2001 Service typical of gasoline engines in passenger cars, sport utility vehicles,
What does SG mean in motor oil?
The letter combinations are performance ratings from the American Petroleum Institute, or API. When your van was manufactured, the top-of-the-line motor oil was rated SG, so that’s what Ford called for. TOM: Well, since then, oils have continued to improve.
What does SH 1994 mean in engine oil?
