I just bought 10w-40 fully synthetic for my rebuilt V5 STi. But seriously, you will get about 900,000 different answers, its just something to make up your own mind about lol.
Talk to the rebuilder etc.
Looking at replacing the original VF28 in my V5 next year as its getting rather noisy and has done some 230kms. Just want to replace with something similar. ie another VF28 or if I can't get one a VF23/TD05-16g. Any suggestions/tips etc?
It's a mix of group 4 and 5 synthetics while the HPR-10 is group 3, therefore not a true fully synthetic oil.
The full synthetic stuff less prone to shear apparently thus better for racing.

The research told me plenty, I didn't say I wasn't taking it into consideration I asked for the OPINION of clubsub members. Was told to use whatever I want by rebuilder lol
This question has been asked millions of times, and yes i have done LOADS of research but just want your opinions...
Rebuilt V5 STi motor - what oil viscosity should i be using? 5-30, 5-40 or 10-40?
Probably going to go with Penrite brand.
