A must have for smaller engines

Used this for years with great results. Yes the quality of powered equipment isn't what it used to be but one of the biggest culprits of small engine longevity is the ethanol in gasoline. Horrible for push mowers and weed eater parts. I put one ounce in every 5 gallon can of gas which I truly believe makes a big difference. Well worth the money.

Walmart has the overall best price on the market. Delivery is always quick and easy therefore making it more appropriate to purchase online in addition, the product itself is a must use in any gasoline engine . I wish that Walmart would let me know when they're having a sale on StarTron.

From what I've researched, this is among the best fuel treatments available. I've used it numerous times to stabilize gas for a year , and never a problem. ( that said, I've also stored non-ethanol gas with no treatment at all, for the same amount of time, and it also ran fine).
