Perhaps this is a silly question, and not even exclusively a bike one, but I'll ask it all the same... Whats the best way to get oil stains off a concrete driveway?? The reason I ask is I topped up my 2-stroke oil resevoir to ~2/3 full yesterday, which is higher than normal for me - I usually only top it to half full, after every ride to get myself into the habit of checking it regularly (still a new rider). Anyway, I came out about 15 min later to gaze lovingly at her just-washed curves (the bike, not the g/f) and found a nice pool of Motul 600 leaking out onto the driveway. Bugger... After taking the rear fairing off I discovered something interesting. The oil resevoir has a seperate plug for the oil level indicator, and it turns out not only is it very loose, but it is a coupla inches lower than the top of the tank, so if it is filled much over half full, the plug floats out and the oil leaks everywhere. Double bugger. Easy fixed with a bit of electric tape around the ill-fitting plug, before putting it back in, but now I have a dirty great big oil stain in the middle of my driveway. A rental too. (Groan) Mates have suggested just about everything under the sun to get it out, one even advocated coke. I can't even work out if that suggestion was serious! As I'm prone to tinkering, even when things aint broke I'm sure this won't be the last spill, so does anyone have any 100% gold remedies?
