Silkoline Pro 10w-50 or Silkoline Pro 5w- 40

Which one would you choose out of the two ? and why ?

 

what car?
standard/modified?
engine temps?
track or day to day use?
age?

 

Sorry, its on mine 99 RB5 WR Sport, standard at the moment other than an air panel filter.
I usualy use the pro s 10w-50, just wondering if its worth me changing grades as my next oil change is due.

It wont be standard for long though its soon to be mapped (by sept @ latest) and a vf34 going on.

 

10-50 for me Matt / Olly at RCM said put the stuff in my car..... and that's good enough for me

PS It's now called Titan Fuchs (or Fuchs Titan )

 

yea the last bottle i had was the fuchs titan the renamed one, looks like i'll stick with that then.

 

I use the 10-50 but on a forged 2.5

 

Rb5 Is a UK car? If so...

Stick with what the people who designed the engine recommend in the Subaru handbook... 10w/40 A nice fully synthetic Millers oil is what I used in my UK turbo and ran beautiful.

 

UK car was never meant to run on a VF turbo

Hasn't fitted it yet though so might as well stick with manufacture recommendations oil wise until then.

Lots of mods + as suggested by Oilman
