I've been using Castrol oils for my cars and bikes for over 40 years and I'vs never found a reason to consider changing. My engines have worked well without problems for years and since I've been using Magnatec on the households two cars, everything has been just as good. It's an old line but,' 'if it ain't broke, don't fix it'. It's true!

I'm no mechanic, and can't give you any genuine reason why I should know (because I don't), but I'd trust any Castrol product to be as good as it gets.

great oil. I am using it since 2010 in all my cars and it is very good with start-stop systems.
