in the summer months. i drove the piss out of it, so a heavier oil was a good thing. i think with a quality oil cooler like a mocal or something you wouldnt need such a heavy oil, but VR’s have pretty high oil temps as you know.
i think with a good cooler a 10-40 wouldnt be a problem at all. people that run this thin piss oil, ill never understand. maybe in a prius, but a car you will rev and keep the rpm’s kind of high, there is not reason to skimp out. 40w or better.
some one the new M’s spec 5w-60 :ohnoes
- if the castrol 5w-50 was available back in 2003 i would have used it for a better cold start, but it used no oil when i used 50w, when i got it it wss on some 10-30 junk and would use oil.
