Re: extra gas
i run opti2 oil at 100:1 and started worrying that if i ever ran out of gas i'd have to dump cheap oil in at the gas station, and i don't know (or want to know) how that would affect my engine.
so i started carrying around a 1oz. hotel shampoo bottle full of opti2. that'll give me two tankfulls, and it's about the size of a tube of chapstick.
i was gonna use an eyedrops bottle, but it still had eyedrops in it.
