Can anyone suggest a decent sensibly priced engine oil for a second road car mildly tuned to 350HP which mainly gets track use with occasional Sunday blasts. Millers 10 40 has previously been used is this still the popular choice?

 

What year is the car?

Cheers

Tim

 

Hi Tim early classic with Newage WRX bottom end.

 

Hi

Thanks for that, I'd say a good 10w-40 is the best option.

The best ones are the Gulf Competition, Motul 300V, Redline and Millers CFS.

if its tracked then personally a 10w50 CFS or the fruitier CFS NT................

0191-4103770

 

Is 10w50 thicker? I never understand oils!

 

Yes, but only when hot. The SAE50 is slightly thicker then SAE40 at 100degc.

Would slightly thicker be better to use I'm using a 5w/40 at the moment. Millers CFS

 

Depends, what year is your impreza? Is it modified? And what kind of use does it get.

2003 WRX 108.000 on the clock. FSH
VF34 Turbo

When Mapped will be around 330-350bhp with supporting Mods. Fast Road car with one or two track days a year!

 

I would probably go for a top quality 5w-40 rather than anything thicker, I can't see the oil getting massively hot. Something like Fuchs Pro S, Millers CFS, Gulf Competition, Motul 300V or Red Line would be ideal.
