How long does petrol last?

I sincerely hope not! Nobody's mentioned it over here, so I hope they haven't slipped it in without telling anybody.

Yeah thats a good idea Easy - i'll hardly be walking back to where i ran out of fuel the next day anyway and i don't have something that i can put the GZ in the back of to bring to a petrol station

Old gas will smell like varnish.

VERY old gas......
It is of questionable value LONG before it gets that bad.

There was a guy on another forum that was so cheap, every time he did an oil change he'd save the oil and put it in his gas tank a little at a time with each fill up, and burn it till it was gone. And no, we're not talking about a 2 cycle engine here. Guy claimed he never had a problem. The oil probably didn't have much energy, but it must have had some.

I'm not suggesting this, and have never done it myself.

Ha that sounds like FAR more trouble than it's worth

That's what I do with any left-over 2-cycle mix I have in the spring; mix it with my lawn mower gas......but that is 50:1 before the second mix. It's good upper cylinder lube.

I would like to know how often he had a plugged fuel filter. Dirty contaminated oil has got to be a really bad idea.

A good upper cylinder lubricant? I've got an unopened tube (around toothpaste tube size) of 2 stroke oil that I used to carry on my two stroke bike a few years back, for emergencies. Do you reckon it'll do the gz engine some good? If so, what quantity to a tankful. In England, mamy, many, years ago they used to have dispensers of upper cylinder lubricant at the pumps, & you put in one "shot" per gallon. As I understood it, you were just putting back what the petrol refining took out. But, if 2 stroke oil does the job, & is in any way useful, I'll give it a try. :2tup:

You'd be surprised how many bikes don't even have fuel filters. Anyway, as I said, the guy claimed he didn't have any trouble from the practice. Thinking about it, any bike I've had with a multi plate wet clutch has had some small metal particles from normal clutch wear in the used oil. Probably wouldn't do much for carburetor jets or injector nozzles. I don't plan on taking this practice up myself.
