STA-BIL Fast Fix Small Engine Treatment, 4 oz
Fast Fix in the 4 oz bottle — the one-tank rescue shot for a small engine that runs rough or barely runs.
STA-BIL — ready for the first pull of spring





Two-stroke equipment lives and dies by its premix, so we built ours full-synthetic and smoke-shy, with our own stabilizer blended in — because mixed fuel sits in trimmer tanks far longer than anyone plans.
One bottle covers the two-stroke shelf: trimmers, blowers, saws, and the premix can itself, which stays fresh instead of souring between weekends.
Prices and availability are read from each product’s live retail listing — the red button opens it in a new tab.
The premix that forgives a forgotten fuel can.
Modern ester protection for pistons that rev high and run hot.
The premix keeps through the pauses — no more dumping sour mix.
Burns clean enough to keep plugs, ports and neighbours happy.
Marked bottle, clear ratios, no guesswork at the fuel can.

5.0It's nearly impossible to give a quantitative review of oil, but assuming the oil component is as good as other brands the feature that really drew me to STA-BIL is that the stabilizer is mixed right in. I often forget to put it in the fuel and measuring the amount for 1 gallon of fuel is not easy with the clever stabilizer bottle. This is a respectable brand and I expect the oil is as good as any other brand. The 12 pack pricing is also about the best I have seen, so not only do I get the combined additive I save a few pennies in the process. I do wonder how they can say this makes 1 gallon at 50:1 OR 40:1 - that should depend on the amount of gas used in the mix - though I have seen other brands list the mix like this - how does it know? I take the simple approach and use 1 bottle per gallon, end of story.
