Cheap valvoline 10-30. Gotta change mine out pretty often at 1k miles though.

Might give rotella a try.

 

Castrol Edge 10w60 !

 

Fuchs Titan Pro S (used to be known as Silkolene) 5w-30.

One of the best esther synthetic oils you can buy.

 

I'm with these guys.

 

using Castrol edge titanium
available @ walmart

 

Amsoil 10W-40 or Rotella T6 5W-40

Haven't had any problems with either. I ran Royal Purple for 600 miles when I was turbo and had problems with it breaking down so I changed it.

Also I would recommend changing oil atleast every 3000 miles. I changed mine every 2000 even while running synthetic.

 

Yeah last year when I was running mobile 1 I was changing my oil every 2000 miles or so.

 

I plan on giving Rotella T6 5W-40 a try on my next oil change. Always used it in my WRX and it was great stuff, I hope the S2000 likes it just as much.

 

Im gonna switch to brad penn on my next oil change, what do you guys recommend 10w30?

 

This guy likes his blend of oil(50% AFE 0w-20 and 50% M1R 0W50)in a C6 Z06, Lotus 260 and a 911 Turbo S.
