OK, let me give you some background info on my car... I have a 95 Civic EX with a Drag turbo kit (installing now). I have nearly 99k miles on the car and I have used Mobil 1 Tri-Syn 5W-30 since I got the car at 87k. Should I continue using the same oil or should I upgrade to some thicker oil? I really need some suggestions because I am kinda new at this. Thanks in advance.

 

i use 10-30 i tried 10-40 but felt really thick. i recomend thicker oil

 

How many miles did you have on your car?
