"We have found the products to be superb in every aspect. The latest synthetic oils give a rise in horsepower and the protection against wear is unparalleled. They are without doubt the best oils I have used since I started racing in the 60's. And the brilliant product range is backed up by a fantastic team of people, who are always ready to help. I am very proud that we are supported by Rock Oil.”

"Rock Oil every time for me. We use 'Synthesis 4 Racing' and run our engines to 16,100rpm...1,600rpm above their designed engine speed. No mechanical problems whatsoever last season. We used the Guardian prior to raising the rev limit with great success, but were advised by the technical department to up it to the higher spec fully synthetic with the extra rpm we were using. Not a problem with clutch slip as some other brands cause and on inspecting the engine ready for the 2010 season found no wear at all...just as a matter of course i fitted a new cam chain and on setting the valve clearances on the rebuild found only 3 that needed slight adjustment. What more can i say...no dnf's...only off the top step of the podium twice (due to grid allocation) two outright F400 lap records, three club lap records, and a £75 parts bill for the rebuild...Cheap racing I call that and that suggests to me that good oil is worth the money and my money goes with Rock Oil."
