If convenience were the only factor, we'd recommend everyone pick up TruFuel—the advantages and features are spot-on and very important for the life and health of your outdoor power equipment. Justifying the cost, however, is another issue entirely.  

Overall Score 8.2 (out of 10)

Have you heard of TruFuel Premixed Gas and Oil? Let’s start at the basics. What if you didn’t have to mix gas anymore? And I’m not talking about battery-powered outdoor lawn equipment. I mean—what if your fuel came already premixed and ready to go? And what if it never went bad? Mixing gas into that 1-gallon plastic container has been a necessary task in maintaining my personal lawn equipment. And while you get used to it, the fact is—you must be precise in your oil-to-gas mixing. It’s a hassle.

Then there’s the issue of dealing with Ethanol fuel vs. ethanol-free solutions.. Gas tends to go bad over time.. You have the mess you make when mixing it up.. You get the idea.

That’s where TruFuel premixed gas came about. For small engine equipment owners, TruFuel provides a pre-packaged, ready-to-use, fuel system. They have solutions for both two and four-stroke small-displacement engines—like those used in lawnmowers, trimmers, and chainsaws.

What is TruFuel?

TruFuel premixed gas is engineered with premium, high-octane, ethanol-free fuel, and it’s mixed with high-quality synthetic oil. Because of this, TruFuel prevents corrosion and build-up. Over time, Ethanol (E-15) separates the gasoline from the oil in a two-stroke mix. It even introduces water to the fuel.

The Outdoor Power Equipment Institute (OPEI) backs up these claims and recommends against the use of E-15 fuel. A related benefit of TruFuel is that it stays stable over longer periods of time and doesn’t break down quickly like traditional oil-gas fuel mixes. In fact, TruFuel claims a life span of 2-years after opening, and the fuel is guaranteed to never separate. That means you have fewer issues with winterizing your equipment. You also don’t have to worry if your mower or trimmer sits for a month or two unused.

TruFuel 2-cycle and 4-cycle gas

TruFuel premixed gas made a splash as the first pre-mixed product for two-stroke engines in this country. It comes in 50:1 and 40:1 mix ratios (gas to oil) as well as in a 4-cycle formula without oil. You can find it at The Home Depot, Walmart, and other retailers. It may seem an odd product for home and pro users if you focus on the small bottles, but TruFuel is also available in more than just the 32 and 110-ounce containers.

Commercial or fleet users can purchase 4.375-gallon containers and even 48-gallon drums. Those come at a significant discount over the bottled versions. For the reduction in maintenance, this may prove to save some companies money—even over traditional ethanol-free fuel. For the homeowner, you pay for the features and convenience TruFuel provides. It is VERY convenient. It simply gives you the choice of wanting to pay the additional cost or not.

Doing the TruFuel Premixed Gas Cost per Gallon Math

TruFuel comes at a premium price. You can pick up a case of six cans (192 ounces, or 1.5 gallons) for around $35. That works out to about $23.33/gallon. If we estimate (high) that Ethanol-free currently runs around $4.25/gallon and an oil mix would add another $1 to that (also generous). You can quickly see that the consumer level of TruFuel might dissuade some from jumping right in.

We were told by the salesperson at home depot that we had to run 50:1 Trufuel in our new blower It is ridiculous in price for sure. He also told us that we could buy this directly from a place near our home, but I have yet to find any retailer or wholesaler who will sell me a gallon of this stuff so we are stuck with paying this horrible price to run our equipment ;-(


My belief is anyone giving a good review must know someone and gets its free. I’ve had two weed eater blow up using this product, when I took them in for repairs , was asked what product I was using, when I told him trufuel , I was told he’s had more weed eaters come in for repairs using this product , he believes that’s what happened to mine. This product needs to be researched in depth. Will not use this product on my new weed eater. On a scale of 10 , it’s gets a negative zero. Wake up… Read more »


While TruFuel is far too expensive to use regularly, it works extremely well as fuel to add to the tank at the very end of the season when you will be storing your engine. Run the tank almost to empty then add a pint or two of TruFuel Running an engine “dry” doesn’t always clear the carb and what is left over will turn to varnish over time. Adding TruFuel and running for a while before winterizing is easier than draining the carb and leaves you with some fuel in case you do want to run the motor before the… Read more »
