Engine oil

[nick crisp]

For me , there's never been any argument that car and motorcycle oils are, and need to be, different. I'm not so cynical that I disbelieve everything the oil companies say. I also wouldn't discount claims of improved fuel consumption and increased power output totally. But as Slaninar says, those benefits may be minimal. The oil companies make vast profits as we all know, but they also stand to lose a great deal if found to be making false claims. Your way of approaching the problem is a much more practical solution from our point of view. But I never thought I'd find the subject so fascinating - must be getting old!
