is Castrol GTX Magnatec 10W-40 any good ? thats what ive allways used in my starlets . tho was going to use Motul v300 10/40 but it had a pix of a motorbike on the bottle is it the seams stuff for cars too ? cheers
The GTX is pretty basic stuff, cheap mineral oil. The Motul 300v is as good as it gets, the bike stuff is the same as the car stuff.
