Castrol oil has always been No.1 for performance. During my many years of motorcycle racing both road and enduro I've always depended on Castrol for both four stroke and two stroke machines. It goes without saying that I use it for my diesel 4 wheel drive and petrol cars without a problem. Sure its a bit more expensive than other brands but its a price I gladly pay for superior performance and peace of mind.
