Hi...thanks for everyone's reply
I really appreciate it
another question is I learned that on the market is 5w30, 10w30 and 15w50. but the 15w50 don't have the "AMERICAN PETROLEUM INSTITUTE for gasoline engines certified" stamp and also missing the "energy conserving" 5w30 lable like the others...has any one use 15w50 and what does that means if missing those lables,stamps? but I didn't find out about this until after the oil change

and for my first oil change, I use the 15W-50 one....the reason was that before the change, my car quite often runs up to 90-100 degrees I figure since my engine is hot running, I should go for 15W-50 one.......did I do the right choice?
