But I found 2 old engine oil "tong" in my store..
1 of it says: "Exceeds API SL" . The other 1 says: "API SM".
Both are same SAE 5w-30 grade.
Are they the same grade/type of engine oil?
Because I plan to mix them together and use for next time engine oil change.. Save some money.
Please let me know if I'm making a big mistake mixing them together.
