O/T. Old gas in truck

Steve A W · May 28, 2022

Im going to fix my 03 suburban and get it back on the road.
The truck has been sitting for fifteen months.
It has e10 gas in it.
Will it give me trouble or should I drain it.
How best to drain it? I already tried one of those shaker siphon
hoses , no luck with it.
And will the old gas give me trouble getting the emission test.
Thanks for any help.

add some fuel stabilizer to it and burn that gas out. no use to drain it. or top it off also. i just started my W9 today that was sitting for 2 years and 2 turns it was running.

It should be fine.

Try cycling the ignition 3-4 times to pressurize the fuel system before trying to crank it.

My mom's old Tarus sat for probably 5 years and the gas was about 7-8 year old E10. A new battery and it fired like it had been run the day before! No check engine light, ran perfect!

There are new cars that sit in the lot much longer than that. (Well, used to be) Run it as is. Or completely fill the tank with fresh gas and run it. You should have no problems.

I have a similar vehicle that sat for about a year. Ran fine when I started it. Maybe a little rough at first.

I had a car that sat for about that long. It needed a fuel pump so I had to take the tank out and was able to clean it however I didn't do anything with the fuel lines. After I got it on the road I had to change the in-line fuel filter about every 500 miles for more than a year. It kept getting plugged up and cut off the gas. I had to carry a new fuel filter and wrenches everywhere I went.

From personal experience, if it doesn't smell like varnish, add a can of Seafoam to it and run it. If it smells like varnish, anything you add to it will be that much more bad gas you have to remove.
