am i the only person in the world who thinks castrol magnatec actually destroys engines?
Yeah, more than likely.
its not unfounded:-
latest addition to the dub family mk2vr6 was advertised as a smoker, apparent stem seals, changed oil to aftermarket 10w40 3000 miles on no oil use..
when the oil was introduced years ago, brend new (recon actually) engine in my 205xs - 500 miles on magnatec and it was tapping like riverdance, changed back to a generic 10w40 and again silent engine...
saxo VTR first service 10K, used this stuff again, slight tapping again.. went to some comma 10w40 and a nice silent - but crap engine... (reasoning behind doing a DIY service was i imprted it from belgium personally and only has 12mth warranty)
just my personal preference i suppose but id put any premium motor factors brand in over that any day
