No David is saying that 80% of the failed engines he sees are using 0w or 5w oil. Assuming that most people follow Subaru recommendations and use 5w oil - say 80% of people - then this does not mean that ow or 5w oil is any more likely to be the cause of an engine fail than other oils. You would expect to see more fails from cars using ow or 5w oils if more cars are using these oils and fewer fails from cars using thicker oils if less cars are using these oils - that's the point i'm making.

They might want to update their website then!

Unless the customer specifies otherwise, AFAIK They've used Silkolene Pro R (now called Fuchs Tiutan) 15/50

IMO Motul & Millers race products are the best quality oils in the market place and ultimately you are paying for their "multi-ester" synthetic technology..........
the only other race oil manufacturer i would entertain is the pukka Shell Racing (not the helix common or garden types you get in Halfrauds, etc.)
lots of other companies claim "ester technology" or synthetic formulated or other tosh, its basically verging on "snake-oil" type advertising for the uninitiated

I've run 15w50 and a 5w40 on classics and new age cars without issues, alot of it will be the engine and oil changes, no point running a good oil in a tired/worn engine where you need a thicker oil, I run a 5w40 fully synthetic on both my classic type R and STI Spec C now 
but I wouild never run a 0w oil, bit of a 
that.

SPOT ON, I AM DEFINITELY CONFUSED, I FEEL LIKE SLASHING MY WRISTS WITH ALL THIS INFO OVER VISCOSITY.
My car is due an oil change anytime soon, currently using Shell Helix Ultra 5w/40, but stuck on which oil to purchase. I have seen two which I like, and they are:

Are you an engine builder or motor engineer perhaps?

Good stuff if you're going to be tracking your car and using WOT a lot. However for road use it's too thick and causes unnecessary drag whilst getting up to temperature and thus sapping power. I would not use it on a road car, far better to stick with 10w 40 or 10w 50 if you're running more power than standard and like to use it.

Have been using Millers, motul, Fuchs and now tried Gulf Competition , 5/40 for winter....Engine seems smooth, oil consumption is same , had to top it up recently after 4 months of owning the car but there were many blasts, mapping session, dyno run involved so might not be the case .... Will try 15/50 on Cadwell later on 2013

thanks for that, I shall bear that in mind when choosing my next oil.
not familiar with WOT terminology ?

Basically you want a fully Synth Ester based oil. 10/50 seems like a commonly used grade, RCM (who know a thing or two about Scoobs) actually use 15/50 as do APi. I use this grade in my quite heavily modified Hawk
I would steer clear of 5w - I'll get flamed for that as Subaru UK recommend it, but several specialists (who build have rebuilt more of these engines than we've had hot dinners) say it's not optimal for Scoobs!

- Exceptional Level Of Protection
- Suitable For A Range OF Race And Rally Applications
- SAE 15w-50
- Available In 1 Ltr And 5 Ltr Bottles
The Competition 15w-50 oil from Gulf is an oil suitable for a wide range of race and rally applications, notably in longer events and in large ( such as American V8s and highly rated 1000bhp ) engines. Its exceptional level of protection against engine wear, especially in high temperature conditions, is ideal where frequent engine rebuilds must be avoided.
Available in 1 Litre and 5 Litre sizes
While these oils are excellent for motorsport / trackday use, they are not recommended for use in road cars, especially if the car or its engine is still under the manufacturers' warranty.
