Fuel life
Submitted by 7739ian on Tue, 2009-01-06 11:30
Having bored the pants off people moaning about how long it has taken to get my boat into the water - it looks like i will launch the weekend after Australia Day. My query is i have a nearly full tank of 50-1 fuel that has sat in the shed for nearly 6 months. Is it useable or too risky? Any advice welcome.

pour it into your car and
pour it into your car and make a fresh batch .... its a little hard to swim home somedays :)
pouring 20lt into a 60 car tank aint going to hurt the car even with the oil in it

How many litres?
If its only 20 litres or so just shake shit out of it to re mix the oil in it and it should still be ok.The oil separates out after a while.I've used fuel that was 12months old without any problems

Keep it - Good investment?
You must have paid $1.40 a litre for it then - keep it until the price goes up again...LOL
Na seriously, just split it half half with your spare tank and freshen it up with new fuel and oil...should be fine then....

buy high octane fuel (ultimate 98 etc)
as it last longer than standard ULP.
but in your case, tip some into a jerry and put some fresh petrol and oil in the tank. Wouldn't hurt to spike it with some octane additive also.

Get rid of it and start with fresh stuff. I was told at tafe that higher octane fuel has a shorter shelf life than standard unleaded.

Not what I've been told
when I put my car on gas, since you try and use the least amount of fuel possible and it can sit in your tank for quite a while, the guy there said use high octane fuel as it doesn't go stale as quick, last 6 months compared to normal ULP which lasts around 4 - 12 weeks.

Pretty sure what they mean
Pretty sure what they mean is you still have enough high octanes to kick the motor. The reality is that if your motor demands high octane mix, it doesn't sit any better than lower octane fuels.

no
the ULP will drop octane rating as it degrades, while PULP will remain the same for a lot longer period.
It has nothing to do with my bog stock commodore V6 ute on dual fuel needing high octane fuel.

I think we might have to
I think we might have to disagree on this, my pal's skyline is really picky on fuel and he only buys from places that turn over their tank fast for that sole reason.

And the high octane is
good for your injectors, we've been told. We've got stale fuel in spare tank, Bob's putting it in the Ford and about half in the 80litre tank, filling up tank and spare when we go (bloody hell when grrrrr) to Leeman.

Dunno that I would believe
Dunno that I would believe anything the fuel companies told me. all geared to push their products onto us poor public that have no real viable alternative. Anyone running their boat on biofuels? Could save your own fish and chip oils..... Just kiddin

Give it to the kids
Our daughters ask if they can borrow $20 for fuel till they get paid... I say better still "come around and I can give you 40 litres". Drain the boat tanks and put it in their cars and away they go... No probs yet and the boat gets fresh fuel when needed.

For cars, Fuel has a life of
For cars, Fuel has a life of about 6months. As evapouration takes its toll, the leftovers is actually stickier and thicker. Using old fuel can cause injectors to stick as they open and close. It will also leave sticky residue throughout the fuel lines, system and pump which in turn can make engines to run leaner from injectors malfunctioning. It will also cause it to smoke grey/black constantly.
If it was me, I'd chuck it and get new fuel along with a flushing additive. Taking chances when unsure might only cost you more in damages.

Thanks everyone
As i don't want to look like a plonker drifting out of sight - i will pour it down the nearest street drain or some other ecologically responsible disposal method.

Put it in the mower, mix it
Put it in the mower, mix it 50/50 with unleaded. will only be a little bit smokey but wont harm the motor.
