I've used Castrol Magnatec in my car and I don't think it makes a lot of difference. The car seems to idle smoother on a cold start but the main reason I bought it is coz it takes heaps longer to 'go black' with contaminants
so it should improve engine durability etc.
Since it's only 10w-40 you'll notice ur oil pressure go through the f*cking roof on hot days but I don't think that matters, just a bit scary
