Would RecommendI had a weedeater stored for 2 years and added new gas (with oil) to old gas. The weedeater would start but would cut off. I found Seafoam recommended online, I purchased Seafoam, used it as directed and it worked the first time. This is a go to product. Thank you!!!

Best fuel treatment, use it on automobiles, etc. !
Would RecommendBest fuel treatment, use it on automobiles, in the lawn mower, weedwhacker, leaf air pusher [I am not a moron, IT does not allow me to put in the actual word because IT says it is a "profanity"),, portable- and not so portable- gas powered generator. Basically, if it runs on liquid fuels, add Sea Foam!

Excellent product
Amazing stuff. I have been using on a 6 hp outboard on our tender/dinghy. I’m recommending this product to everyone who will listen… Especially if they have finicky engines/fuel systems. I only discovered it 3 to 4 years ago and I’m about to buy my fifth or sixth can of it. I’ve given some to my neighbours at the marina, as well as some friends. Used it to treat my lawnmower and backup generator too. This is one of those rare products where you feel great about the purchase. It’s that good.
