Is SF oil the same as SAE?
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 SN oil instead of SF?
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 is SD and CF 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.
Is SJ oil better than SG?
In summary, API SJ represents an improved quality level of motor oil vs API 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.
Can I mix SAE 30 with 10W40?
You can mix straight weights like SAE 10and SAE 30 or multi-grades like 10W30 and 10W40.
Is 10W 30 oil the same as SAE 30?
Nope. SAE 10W30 is an oil that has SAE 10W viscosity(thickness) at low temperatures, and SAE 30 viscosity at high temperatures. The W stands for ‘Winter’. Note that these viscosities are relative, and standardised numbers and no absolutes, the oil doesn’t get thicker when it’s hot, it gets thinner.
Is there a difference between SAE 30 and SAE 10W 30?
Is SAE 30 The Same As 10w30? SAE 30 and 10W30 aren’t the same. SAE 30 is an oil that has a viscosity of 30 at overly high temperatures. The 10W30, on the other hand, has a grade 10 viscosity at low temperatures and grade 30 viscosity when the temperature is high.
Is it OK to use 0W20 instead of 5w30?
Pennzoil’s 0W synthetic motor oils offer the same protection as SAE 5W and gives the additional benefits of faster flow at start-up, enables faster engine warm up and delivers better fuel economy.
