i haven't, but hmm. i never know what to think of these comparisons - do the conditions used actually simulate those in the F20?
still, I wouldn't mind trying it.
a question i've had for ages but keep forgetting to ask - where do you guys find brands of oil like asmoil, motul and especially elf? the big commercial stores (supershit etc) only keep the castrols, valvolines and the mobils amongst others.
I ordered it online, from Harold at performancelub.com
he carry a few brands like Redline, Royal purple and Amsoil. I got my Redline gear oil and Amsoil engine oil from him.
