Won't touch Castrol, used to use it when we stocked it in bulk and it almost cost me several motors. Typically the oil pressure would drop off noticeably with heat / load....like from 60 running to in some cases below 20 after about 500 miles. Happend to me with a 2130 142E, a 1275 Cooper S, a number of customer Jaguars...switched to valvoline / Quaker State and pressure returns with no drop over time. Mobil 1 is fantastic if a little pricy. Have had very good results with the Penrite oils on vintage cars.

Why so light?

That's the consensus of the guys on Swedespeed, i can't dig up the exact link but they say it is some of the best oil out there for the R. It's supposedly a very thick 30 weight when warm and acts more like a 40, yet doesn't deteriorate nearly as badly as mobil 1

Man those guys struggle.

I use only "German" Castrol 0-30 in my R, in oil analysists it comes out better than mobile 1.

Post up the assays. I have not assayed castrol in years. Would be interesting to see a newer run

when I bought my platinum 850 used castrol. car had 15k miles or so, sold it with 212k still with castrol now the car has 265k miles.. still with castrol 10w 30w, still the engine strong as hell.. why is castrol bad?

At 3k in the fleet vehicles we tested castrol had the lowest flash point of any oil tested. Screw wear. I'm more worried about ping. Also 10w30 is insanly light oil.

+1, German Castrol 0-30 is all my Volvo and Saab see. I haven’t used the gold yet, but the green is some of the best stuff I've ever used, and it is thicker almost a 40 weight oil.

Here's a bunch of info on it, Click me

Mobil 1 has a problem with shearing........ so I've been told by some saaber friends.
