What I am trying to find out is what is the most protective oil.What will make the engine last longer in hot stop start and very hard driven cars?
Try Torco oil you cant go wrong, just watch any form of drag racing or cicuit racing in the USA and most of the front cars will be running Torco. As for the people that say the race teams dont run whats being advertised well just imagine you are the manager of mobil 1 and you are giving HRT empty bottles to put Castrol in it mean while you are handing over millions of dollars in sponsorship come on people wake up these companies would never risk something like this it would be the end of them and on top of that the teams cant even fart now a days with out another team nowing about it.
