Hey guys, what kind of oil should I use in a 93 del sol (S) with 130,000 miles. I use mobile one synthetic 5W30 in my 99 prelude, but I am not sure if I should use the same oil? Heavier weight...what not.

What do you people use in a stock engine or what would you recommend.

 

it would depend on where you live. Is it hot or cold there? Would you need a heavier oil or not?

 

I live in indiana, so its both, hot and cold. the summers it can be up to 90's or 100's (on rare days), and winters can get as cold as 20's or lower (again on rare days). So what should I use? Synthetic or not? Weight?

 

on a d15, don't waste your money on synthetic. Even when my d15 started to burn oil, I slapped some 10W40 in it, and it help up fine for a year, and I was BEATING it hoping it would blow. 5w30 should do ya just fine.
