Stale fuel

[2old2boogie]

 
I have an old tank (from a Diversion) that is full of petrol that has been in there for most of the year. It will I know, be trouble if I stick it in the Fazer. But I'm reluctant to waste it.   Is there an additive on the market that will make it useable?

If you're so convinced its a bit stale, bung it in the fazer tank a bit at a time, as you fill with fresh fuel. No problem.

is a tank of petrol worth the possibility of blowing yourself up?

What? If you'd said "worth the risk of transferring rust from the old tank" which is where I thought you were going (or similar) I'd have said fair comment, depending on the state of the old tank, but blowing yourself up? Why would you do that, if you're sensible about how you do the transfer? You might get hit by a bus tomorrow, does that stop you crossing the road? In fact, if you're that risk averse (or incapable/clumsy/incompetent) best you sell your motorcycle right now, they're dangerous you know.  Jeeez....

I'd burn it a couple of litres at a time with fresh fuel, shame to waste it

half a tank topped up with Super Unleaded or a few litres at a time for me. Either way it would be used.

My missus filled up our diesel car with petrol once, luckily there was only about 5-10 litres of the oily stuff in there, and 40 litres ofpetrol. My trusty old fazer 600 burnt the lot with no problems. It was just a bit smelly but ran well. You'd be amazed what these machines can put up with!

Yes that makes sense, dilute it with Super Unleaded. I'll do that. Thanks for the input.

And don't use the last liter or so, as it'll probably have a load of water in it, which will then result in you needing to strip down your fuel system to clean it out!

Maybe blow up was a bit dramatic but i dont know how sensible he is

I wonder how fuel goes "stale" when I sold my trike it was over 6 years since it was last filled up, yes it took a lot of starting, the valve in the carb was stuck so no fuel getting in, flattened a new battery winding it over, but once it got some fuel through is started firing then running and then it was fine, I wonder if it's the engine that gets "stale" i.e. valves not seating maybe rings sticking plugs and points (not many of those about now) dirty, of cause there's the chance of water in the fuel also rust and dirt.
after all oil is 150 million years old?
