this is from the makers of royal purple. they make synthetic oils for high performance machines. this product here will make your engine run 25 to 44 degrees cooler then normal oil.

also for you car freaks as myself, they have a synthetic oil that will give you on average 8hp gain from just swapping all fluids.
