Mixed 2 Cycle gas in a new vehicle?

[SupremePossum]

I have 5 gallons of gasoline that is mixed with 2 Cycle oil, specifically this stuff

Trouble is, I don't have any 2 stroke engines anymore! Can I mix the 5 gallons of gas in with a full tank in my 2019 F150 (36 gallons) and not have any issues?

Is there any injector or cat problems I will run into?

Run a gallon each time you fill the tank, it'll be fine.

If you add the 5 gallons of mix to 30 gallons of fuel in your tank, I can't imagine there being any issues. If anything, the oil will add lubricity which can only be good for things like your fuel injectors.

It will be fine. Just do it on a fillup to dilute the mix.
Have done it for years with my pickup when I want to change out my 2 cycle can.

This is why i come to the forum.

Yesterday one of my kids in the kitchen said "Can you drink that??" and I said in perfect dad fashion: "You can technically drink anything."

(dead silence)

Mixing a small amount like 5 gallons of 2-cycle mixed gas into a 36-gallon tank shouldn’t cause major problems in your F150. The oil concentration will be really low once diluted. Just don’t make a habit of it, since 2-cycle oil isn’t meant for fuel-injected engines and could potentially cause buildup over time. For one-time use, you’re probably okay, but keep an eye on how the truck runs and maybe do a fuel system cleaner later just in case.

Should have told them 1 gallon at a time is fine

I've always dumped my leftover mixed 2 cycle gas into one of the vehicles. It will be fine, the concentration will be very weak once mixed with whats in your vehicles tank.

Just think of it as a fuel pump lube.

Never any problems when I have done it but never put 5 gallons in. My tanks are all 20 gallons or smaller. That is a huge gas tank.

Just an FYI, 5 gal of 50 to 1 is about 13 ounces. Or about 1/3 an ounce per gal in a full 36 gal tank. That's enough to sneak through the combustion process unburned, through cold catalytic converters and possibly into the exhaust system and show up as drips at the tailpipe. Ask me how I know...

Anyway, while the vehicle might tolerate it just fine, it is not ideal. In this case, I'd suggest a much more extreme dilution or not at all. One gal of your mix (2.3 ounces of oil) is much more tolerable in a 36 gal tank.

Even running your truck on straight 50:1 mix (2 quarts of oil for 25 gal of gas) would not be too terribly different from what millions of late 2000's GM AFM engines do every day.

I would pour it in a full tank. If you want to be super careful, just put 1/2 in now and the other half the next time you fill up.

I have been running a mix of 4 oz. marine 2 stroke oil in 26 gallons of gas in my truck for years. So, you can use up the rest of that oil too.

Would a cheap generator be a better use for it?

Trouble is, I dont know if we will have any big outages this year...

Some say good some say no good, hmmmm.

I had a '96 Corolla that my dad bought brand new and starting around 80,000 miles it was burning oil. When he gave it to me at a little over 300,000 miles, it was burning 1 qt of oil every tank of gas. I cleaned the car up, put on a new timing belt, pulleys, water pump, and tires on it and my teen son and daughter put another 100,000 miles on it, burning this much oil, before I took it to the junkyard due to rust issues where the suspension components attach.

One qt of oil every tank (12 or so gallons of gas) works out to around 48:1 on regular motor oil, not clean burning two-cycle oil. It ran fine, got great gas mileage, and there was virtually no smoke except under hard acceleration.

A few ounces of two cycle oil short term in any newer car isnt going to hurt a thing. I'd do it with a smile on my face.

I dumped 2 gallons of last years 40:1 red armor gas plus the last little bit of redarmor oil into my dodge Dakota right after I did the 2nd oil change. It made the oil harsh dark yellow varnish color, not the normal "oil turning black from soot" color.
Didn't seem to hurt anything.

knock it top 100:1 and into any 4 stroke ODPE. I used to top-oil my briggs 3.5hp push Still running well I think 30 years later.
IDK haven't mowed in two years(!)

Usually I dispose of old 2 stroke mix into the engines without cats, pretty much straight or mixed slightly, but if you don't have those, then I like Cujet's plan of 1 gal per tank in the f150. Then the chance for an issue is zero IMO.

Just keep it around and use it as a fuel stabilizer. 1oz/5gal. You could also mix it with some tranny fluid and put it in a squirt bottle and make a nice homemade penetrant oil/lube.
