well if you want cheap oil.

In the Carpe TDM site someone found 5 L motorcycle oil at a very good price, no marketing budget keeps the prices down eh?

I've seen that round before, I've always been tempted to try it but I never trusted the price, then again, with that price I could change it twice as often and not spend anymore XD I might give it a go one day, after all I've heard good reviews
