iv allwaysed used castoral but at £55 for 4L then post its expensive. but i no it is good and was fine on track also.
but as u lot are 15 miles down the road from me it would be cheeper for me 2 change and go with what u use. just wondering thow why u use it or is it just cost?
Mainly because of the high breakdown point, i used mobil 1 and castrol rs in my saff and both dumped oil out the breathers under real hard use, where as pro s did not, it just does a better job of dealing with high temps.
On track using Mobil 1, after a good session out the car would rattle like it had dry lifters, again pro s stopped this issue.
