New here, just curious what, and if there are any, the differences between Castrol 0W-30 and 5W-30 European Formula oils. Obviously the 0 and 5 weight, but i mean as far as whats in them? In a car i recently purchased I would like to run the 5W-30 however it's quite difficult to get it. The 0W-30 is very easy to get, and benefits/problems with running the 0W-30? Car called for 5W-20 from factory but makes good power and will be driven hard so i'm choosing to run a xW-30 weight.
Thank You all.
