Mikey_Boy said:I don't think I said any of that - I'm just trying to point out that oil technology marches on regardless of brand and actually is compatible with an S54 engine. I was also trying to give the forum some more detailed information to try and alleviate any fears that may be on here - however, if no one is interested, I'll exit stage left.
You have made up your own mind on this topic and you'll be pleased to know you are right, as no doubt you have always been.
I can't comment on who I work for, but I've been in engine design and development long enough to know what an oil does...
Still haven't answered my question Mikey :wink: what characteristics does the new oil have that is better than the old spec Castrol ?
Its a genuinely interesting topic & although ive switched my car onto Millers 10w 60 CFs im still curious as to the "benefits" of the Shell over Castrol
