Lets get one thing straight, it's you car at the end of the day so you put in it what you like.
The reason why I post here (apart from selling 6 brands of quality oils) is to give people an informed choice as I always believe it's better to know the facts than believe Oil Companies Marketing Hype.
If you don't like my posts don't read them!
And yes, ALL the 6 brands of oil I sell are used by race teams, that's why I sell them, they are quality!
I have over 300 different products on the shelf and I know them all intimately, that's better than any salesman you'll find across a counter!
Cheers
