Engine oil

[nick crisp]

I think it comes from the supermarkets f****ng up other things they've tried to get into in the past. You'd think they couldn't go far wrong with motor oil. As an example of why I don't use them, if you're going to buy an expensive camera and get serious about photography, you go to a camera specialist rather than a general store. And lets face it, your bike is not cheap -especially when things go wrong. I dunno, is that a good analogy? There again, with online shopping being so prevalent these days, maybe I'm just behind the times, but I'll still stick with what I know and trust at least until someone can completely convince me otherwise.
