Fuel Stabilizers?

Love my 2021 TRD.

After 6 months of ownership, I’m still on the 2nd tank of gas.

The 38 gallon tank seems to have more than one compartment and I’m not sure how long fuel may remain in a compartment, especially for this truck that will see little use.

Is it recommended to use a fuel stabilizer for recreational Tundra’s that see little use?

I hope to take it on two road trips per year and I try to drive it at least once per month for a short freeway trip.

I used Lucas fuel treatment in my 97 taco for over 20 years, in every tank of gas. That thing still runs like new.

 

My opinion - couldn’t hurt, but more importantly is keeping the tank topped off before long periods of inactivity.

Space in a tank is room for humidity to build - water in fuel.

Pure gas in small engines is important as they use a carb and are highly sensitive to that moisture draw. In a V8 - those additives in ethanol gas actually do good - but again this is with frequent use.

Running pure gas might be an idea too in place of a stabilizer. Potentially adding some sort of injector cleaner occasionally before use (but really if it’s not being run regularly and with quality gas - injector cleaning shouldn’t be needed too frequently)

 

Star Tron is cheap may as well add it at each fill up.

 

I would use stabilizer. It is cheap insurance. If you can run non-ethanol gas that would be better too. I have gotten to where I put stabilizer in anything that is going to have gas sitting in it for a few months. I always use it in gas I put in a portable can. I figure, why not.

Startron or marine Stabil is usually what I use.

 

If you are burning through a tank of gas in just three or four months, I wouldn’t worry about it. Stabilizer won’t hurt but I don’t think it is needed.

I don’t know what you mean by compartments inside the tank. I think there are baffles, but everything has to be open so gravity can draw the most gas to the pump. Just don’t fill your tank until your down at 1/4 and that should be fine

 

This is the best I have used for autos, motorcycles, yard machines.

 

I have not had good luck with anything from Sta-Bil unfortunately. Especially chainsaws. Switched over to Star Tron years ago and no issues since.

 

I didnt like the regular stabil either. Startron is good stuff and we use it in the boat motor shop.

The marine 360 however has been great in motorcycles and things with steel tanks. Addresses the ethanol and as it sits in the tank releases fumes that coat the inside of the tank to keep it protected and clean. The inside tank of my 2006 motorcycle was so clean it looked like it had never been used.

 

Just for kicks if your into youtube watch the fortnine video about motorcycle stabilizer. Also project farm covered some good ethanol issues.

Seems most agree that 45-60 days is the self life of ethanol gas and the plastic gas tank in the truck doesn't help.

I agree with posts about volume and air space listed here (the more air space consumed by gas the less the moisture can get in the tank?

Take it for what's it worth.
(note project farm tested the stablizers listed in this thread, no very promising results, but again its the internet).

 

Thanks, guys. Lots of informative replies.

45-60 days is shorter than I thought. Really good to know.

I think I’ll keep it full and just drive it more often. I doesn’t take much to guzzle gas in these trucks.

And probably use Lucas fuel additive in this truck too.

 

Seafoam has worked wonders as a stabilizer for me.

 

Make sure your fuel stabilizer is one that will prevent Ethanol from breaking down or there’s no point. +1 for ethanol free in your case.
