what oil should I use for my 99 civic si?

[9civic7]

i use mobil one fully synthetic 5w30. but if you start to use synthetic you have to keep on using synthetic you can switch back once it gets too expensive. and i change my oil every 2000 miles so it is pretty expensive compared to regular oil.

It doesnt matter when you start using Synthetic...I would have started using it as soon as you bought the car but you didnt know so that okay...its never too late to start...If you are going to switch to synthetic, just make sure that you keep using synthetic and not just keep swithing from regular oil to synthetic
