Filled up my sisters E85 Yukon ...now runs like crap.

[bondservant2]

it s a non flex-fuel engine. When I put fuel in I’m certain I used the E85 pump. It was a blue handle pump. I have called the gas station TWICE to verify that it was E85. But now after about 30-miles, the truck runs terrible and is throwing codes. Dealer said up to $1200 to remove the tank and flush everything out. Any other solution....?
I guess no good deed goes unpunished.....

ETA: it had about 5-gallons in the tank and I added about 10-gallons and burned through about 3-gallons. Should I just go fill it up from another station and see if it rectifies.....?

Let's start with basics.

What year is the truck?
Go look in the glove box at the sticker with the RPO codes and tell us the "L" code.

Do not run it in the meantime.

If you decide to do it, put more fuel in, make sure it is the correct fuel and fill it to help dilute what is in there and give it a chance to work out. I am not suggesting you do that but if you do, fill it. Maybe even premium. Were you filling the tank at the same station your sister does?

Plus, what are the codes? Maybe the running problem has nothing to do with the fuel.

If it only had 5 gallons in the tank and then you put in 10 gallons, that is a 2 to 1 mix and if the fuel is the culprit I would expect that the problem would show up quicker than 30 miles down the road.

curious, why put e85 in a nonFFV?

from what i have read & heard, you dont want it to sit in the tank & fuel system for more than a few days.
as o-rings & rubber lines could have issues.



as mentioned above... dilution may be a possible solution to taking it to dealer.
premium & maybe consider an octane booster too.

probably better to siphon out as much as you can & then add the premium to dilute the remainder.

Yea, you can get the cheap hand pump or electric siphon's with the long skinny hoses and get out as much as you can and then have a 5 gallon can of premium and then drive to known good fuel source and fill it up.

The industry standard is for FlexFuel to come from yellow pump handles and yellow lines. Shell of course, uses yellow handles on all of their pumps. Then of course, there is labeling to help avoid confusion.

It's been 3 hours since you posted, I reckon you've solved the problem in the meantime. If not, I would fill it up with 93 for this and the next couple of tanks.

Yeah. E85 is yellow. E15 is blue. Hmmmm

I'm confused. Title says it's an "E85 Yukon", first post says it's a non-FlexFuel engine and he put in fuel from the blue handle pump which, as has been stated, SHOULD be E15.

What are the codes?

Hence me asking for the L code.

Pump handle color standards are not always adhered to. We have a Murphys in my area that has E0 (pure midgrade gas) with blue pump handles. Some of the other stations have diesel with yellow pump handles, not your typical green handles. Gotta be careful these days.
