got 10/40 magnatec in mine,
but i agree its poo, the tappets sound like engine is sh*gged when its cold, it sounds like a 1.1 fiesta u no the bloody horrible tappet noise, 
i leave it a few minutes before driving it any where until its sorts its self out, 
but i will never put it in there again,
gonna get some mobil i think next time.
