I Googled the heck out of it and haven't found any literature saying it isn't safe, but i figured I'd check here. I have a 2nd gen 3.5. I have a few 5 gallon cans of ethanol free with the recommended amount of Sta-bil in the garage from the last hurricane. Any issue disposing of them in the F150 tank?

 

If it was me I'd fill the tank at the gas station leaving room for 5 gallons and then add a can each time.

AFAIK it will not have any adverse effects even if adding them all at once. There have been a few times years ago I have done this same thing.

 

I don't see why it would be a problem. I have a few cans of gas around, with sta-bil, for small engines (lawnmower, leaf blower, camping generator, etc) that I periodically rotate through the cars if it doesn't get burned in time...never even considered it would be a problem to run through the EcoBoost...though I haven't needed to put any through a car this summer.



Also this. I have been rotating gas with sta-bil through vehicles for a long time, but I never do more than 10 gallons of treated gas at a time (preferably 5) and only when the result is a full tank to dilute the old sta-bil gas.

 

Sounds good. It would be a negligible amount of Stabil in a 36 gallon tank.

 

Not for me. If it were my vehicle I would have no concern. I would just put it in the tank and go. Have been using it for long term storage of gasoline since the 1970s (the Honda product is re-branded Sta Bil). Two ounces in 5 gallons would be dilute enough for me and Sta Bil claims it is fine for injectors. Of course emailing them and asking is the way to get it from the horses mouth.

I've probably put a dozen cans of stabil treated gas in my truck. Both red and green. If it doesn't get used at the lake I just dump it into the truck for the drive home. No problems what so ever.

 

I owned a lawn care service for 15 years at the end of every season my vehicles took all my fuel. The titan never minded 5 gallons of two cycle mixed in at the end of the season.

 

Same as most of the above posts.

I keep 15 gallons of non ethanol premium gas in cans for my generator. Most years I'm lucky if I use 2-3 gallons of it. Once a year I dump the cans - one at a time - into my truck then refill. I use Sta-bil in the cans.

Never an issue - in fact just the opposite. I was amazed at how well my truck ran after I dumped the second can in. I dumped each can in when I had 1/2 tank in my 23 gallon tank. I ended up now using premium gas all the time as the performance on our mountain roads was so much better.
