Old Fuel Question ????????
 

Old Fuel Question ????????
Had 1000 gallons of 93 octane delv to shop in may /o8 used about 900 gallons in the SKATER over a few weekend .. The kidz decided to use some of the last 100 gallons in there dirt bikes yesterday with 2 cycle of course and the YZ 85 & KX 250 lasted only 5 mins .... Can it be the old fuel ??? the YZ piston shattered & 250 will tear open today but can crank it over by hand and compression is gone ... these bikes ran thru winter & spring flawless till this tank of fuel... will drain the 125,450,& 500 this morning before any one starts them .. Same gas ,different cans due to mix ratios ... did put stabil in the 93 tank before winter ... any idears ??? :drink:

Usually on 2 strokes, a failure like that is due to lack of oil. I would be really surprised if that was caused by the fuel, but what do I know?:drink:
It is easy enough to just get rid of the fuel and not take a chance. Sorry dude, that sucks.

When I first looked at your post I thought, well that fuel is only a month old. Then I looked at the year:eek:. Dude, dump that fuel. I ruined the tops of my rod berrings in my boat a few years back. Most likley due to bad fuel. I was using E10 about 6 months old with stabilizer. Sorry about your bad luck, at least it was not in the boat. I have been told only to purchace the amount of fuel you will use in less than a month. Do some searches and you will find a lot of information posted hear. Give them a update when you find them and bring them back to the top. Maybe it will help someone else getting ready to make the same mistake.

You really hink that fuel would be that flat from that amount of time??

The problem is getting rid of that much fuel is going to take a permit of some kind. You can't just pull the plug.

Why didn't you run it through the cars all winter??

The fuel is 13 months old.

good quality fuel in a sealed barrel will last a year easy. if the barrel is open to atmosphere it will get stale in about 6 mos... but having said that, i think eddie is correct... it sounds like lack of oil. when the fuel gets stale it just doesn't want to burn... nothing that i know or understand would suggest that it would cause detonation or lack of lube in a 2 cycle...

the evidence SEEMS overwhelming that it was the fuel but if that's true, i can't think of any factual based reasoning to explain it...

Hi! I tried to run 7 or 8 month old gas in my lawn mower this year and had to drain it out and put fresh in. It was 93 and had stabil in it, no oil mix. Was running pretty rough and rpm wasn't right then it died out. I knew it was the fuel right away and drained it before it screwed it up. Put fresh premium in it fired up and was good right away! It seems like the premium stays a little better then the regular so I run it even in the lawnmower. lol Good luck Charlie

Thanks Eddie they've burnt up plenty of motors on the wrong mix ratio but this one is wierd 2 motors in 5 mins and there thinkin if they went to the gas station for fresh 93 they'd be runnin today ... Im just glad they never pulled the SKATER up to the tank the last 2 weeks and helped me out and topped it off :eek: they should be able to burn thru it in the pick up and the lawnmower :drink:

Same fuel in 3 different cans mixed 32-1 ,42-1 , 50-1 the 250 there gonna take it apart after lunch and see what it looks like . no compression for kick start but they say they can pull start with a pick up :coolcowboy: sounds like they should dump it all and use it for weed killer on the driveway :eek: NO SMOKING !!!!!!!!!

A PERMIT ???????????? mmmmmmmmmmmmmm dont need no stinkin permit :coolcowboy::lolhit:

Old fuel will drop in octane and hi-perf 2-strokes are more prone to detonate. A shattered piston is probably from the piston getting hammered on from deto. Crack the other engine open and I'm betting there is a hole in the top of the piston from deto.

Get rid of the fuel or run it in your lawn mower. :D

That fuel is so old I would not run it in my mower. Don't know what you could do with it at this point. Is that pure gas or E10?

thanks will see what we find :drink:

was pure 93 octane and put some stabil in for winter :drink:

I had 50 gallons of super sit in my old boat without stabilizer for 3+ years. As soon as the carbs got fuel it fired right up. Before I put it in the water I sucked the old fuel out and put fresh in though. The old gas went into a 70's RV and ran fine mixed with another 30 gallons. The new boats fuel sits for 6 months without stabilizer and half tanks (50G a side). Filler up and take it easy for the first tank. The lawn mower and weed eater fire up every year, with a few extra pulls, with 6-7 month old gas. My CR250 is a pain to start if I leave fuel in the bowl for a week so I drain the bowl after each ride. Turn the gas on, one maybe 2 kicks and it starts. I think volume plays a large part in fuel going bad and climate as well. These fuel tanks are all in heated storage in the Seattle area.

I just pulled out about 50 gallons of 10 year old gas out of my boat that I just got. The boat actually ran on it but I did not want to take the chance of running a motor on load with fuel that was that old. I use it in my golf cart and lawn mower and it has been fine. Now this is PRE E10 gas so maybe that has something to do with it? You can use what you have left to start a few bon fires!! :D
