We have a small-engine mechanic who turned us onto SeaFoam motor treatment -- and against most gasoline preservatives and treatments. He said he'd drained, or seen inside, thousands of gasoline tanks, and the stuff sold as gasoline storage additives was often still there, sitting as gel on the bottom of the tank. Just gunk. He also said most brands of engine treatment weren't worth the money. However, he swore by SeaFoam, which I'd never tried at the time, and my experience since has proved him out. I've had many rough-running engines find their power and performance again, with nothing different, but a shot of SeaFoam in the gas tank (and the crankcase). We own a number of vehicles and equipment with small engines, from a compact backhoe, to a ride'em Husqvarna mower, weedwacker, chainsaw -- and on the larger size, a Honda SUV and Ford F150 pickup. All of them have benefited greatly from the regular use of SeaFoam. However, when we're running the road vehicles a lot, especially in the summer, we go through gas and don't necessarily add SeaFoam with every fill. Recently, the Ford began to run rough. It stalled as I pulled up to corners and lights. In the past, that would have meant a mechanic and an expensive tune-up. All I did was go for a fill-up, and started by adding a full can of SeaFoam. Problem solved, just like that. The Terramite (made in the USA) backhoe is not used a lot -- and as with most motors, that is a problem. It's bad for an engine not to run it -- and especially, in most cases, for it to sit with gas in the tank. The backhoe has a Kohler Command 25-horse gasoline engine that powers the hydraulics that run the wheels, steering, front-loader, and backhoe. I change the spark plugs each season, but it, like my Stihl chainsaw, and 6500 watt backup (gasoline) generator, and for that matter, all the small engines, can be hard to start after a hiatus. And even when they get going, they'll run rough. I used to drain the tanks frequently, then run them dry, then fill again before use, and hope for the best. But SeaFoam has changed all that. Throughout the summer, I can leave treated gas in the tank, and have little problems with starts or rough running. In the smaller equipment, I dose the gasoline with each fill (1 oz per gallon), as SeaFoam cleans both carburetors and full injection systems. It is good for gasoline and diesel engines. Added to your crankcase (1.5 oz per quart of oil), it cleans deposits and quiets noisy lifters. These days, most gasoline is mixed with ethanol and that's a bad thing for small engines. Ethanol goes hand in hand with water -- and as we all know, water in the gas is anathema to motors. Again, my small engine mechanic told me, 90% of the no-start problems he had to deal with were caused by ethanol-caused water in the fuel system. SeaFoam actually controls moisture and prevents this problem. It also de-ices and is anti-gel. In my opinion, when it comes to gasoline and diesel engines, large and small, SeaFoam is THE Silver Bullet. My equipment is often running, while my neighbors are running with theirs to the shop. I've told many about SeaFoam, but some people seem to want to do it the hard way. By the way, I also swear by PRI-G fuel additive for long-term gasoline storage. I keep 100 gallons of gas in tanks for emergency use. We are in a rural, wilderness area. I was introduced to that by survival expert, Steve Harris. He said he's had gasoline that was 10 years old still run equipment, because he'd added PRI-G to it (you can buy here on Amazon). Of course, you have to remember to add more PRI-G each year -- that's the catch. So our rule of thumb is, PRI-G for long term fuel storage -- and SeaFoam for month to month. Also -- this price is right! Of course, when you compare the cost of equipment breakdown, and having to take anything to a mechanic, this is almost free. However, apples to apples, this price is cheaper than Walmart -- and up to $4 cheaper per can than many auto supply and hardware stores. Can't say enough good things about this product! Highly recommended.

I have used Seafoam for decades and this stuff just works,.. I simply can’t recommend it enough 👍🏻🇺🇸

Oh Glorious Seafoam, how shall I count the ways? I had my doubts as to whether this product would work, ruin my engine, or do nothing. I was happily contradicted on all counts! I did my research, like a smart woman, and realized that most newer engines (90's and up) don't benefit whatsoever from people putting Seafoam in the carburator with the engine running (until you kill the engine), but guys still do this because it's WAY MACHO (and let's face it, guys want to appear macho) to see all that white smoke billowing out of your car like it's about to explode. By the way, look it up, this can actually harm your car and it doesn't do what guys think it does (ie., clean anything much) because that's for old 80s cars, I mean REALLY OLD. It's not intended for using on 90s and newer car except in the gas tank. If your car was built when people were still wearing mullets, too much hairspray, or bell-bottoms aka, the 70s or 80s, then GO for it and put it everywhere! lol In reality, all you need to do is drive to the gas station, pour your whole can of Seafoam into the gas tank (use a funnel), then fill up the tank with gas and voila! Hint: it's dangerous not to then fill up the tank because that can end up costing you big bucks too and engine problems (as in hole in the wallet). Just fill up people. Anyway, then drive around like the dickens until you burn your whole gas tank up. Your car will feel weird, like it has pep, then no pep, etc., until the gas is all used up. Then fill up your tank after it empties and your car will feel way peppier than before, the engine will sound great, and you will pass that pesky (read:evil) California Smog Test with flying colors! I have a 99 Civic with over 150 k miles and passed at low to medium levels on all the smog check items. Before using Seafoam, my car was smoking out the exhaust pipe like crazy and smelled like burnt tires all the time. No way I would have passed that smog. Now I am so happy to have tried this; hardly a puff of smoke is noticeable from my exhaust pipe now! Thanks to all the nice mechanically-inclined people online who shared their useful knowledge (and thanks to those wanna-be "mechanical macho-men" who shared their follies on what NOT to do). My point is, the carburetor thing (i.e. brake line that has the vacuum suction), for most cars, will be unnecessary to pour sSeafoam in there (I say this out of the kindness of my heart; I hope it helps someone!). Do the research. It is potentially harmful! In all fairness, before the Smog, I also had my oil and air filter changed, my tires inflated, ran the car for about 25 minutes on the highway, and used-up the Seafoam and the gas tank a week earlier, but I am 100% sure it was the Seafoam that did the trick because in the past the oil changes didn't affect my car smoke; now there's no smoke. I should also add that the last smog test I did was 2 years ago and I passed by the skin of my teeth. How is it that I added 70k plus miles since then and passed with lower numbers? Ummm, you get the picture. I give Seafoam 5 stars, but I give the shipping of this item 1 star because it ships out one week after you purchase it, which sucks and should not be labeled as Prime because it arrives very late to your home, although the shipping is free. Regardless, I love Seafoam and if it were a person, I'd kiss it.

I've been using this product in my 2015 Ford F-150 for more than five years, and it's one of the few fuel additives that has earned a permanent spot in my maintenance routine. I originally started using it as preventive maintenance, but over time I noticed the engine seemed to run smoother after treatment. It's not the kind of product that suddenly turns your truck into a race car, but it has consistently done what I hoped it would do. I've purchased and used it multiple times over the years, which probably says more than anything else I could write. If a product doesn't work or isn't worth the money, I usually don't buy it again. This one keeps finding its way back into my shopping cart. I trust the product, I've had good results with it, and I think it's a reasonable value for the money. Based on my experience, I'll continue using it as part of my regular maintenance routine. If you believe in taking care of your vehicle before problems start, this has been a worthwhile purchase for me.

Love using this product. No issues and easy to use.

Awesome stuff. I do not typically leave a review. No negative reviews (just don’t buy again). This miracle in a can is amazing. So after AI doping out what may be my problem I sought this product out. Chat GBT determined that my Kia Soul may have sticky oil piston rings. My Soul was consuming 1 quart oil every 700 miles. I put 4 ounces into the oil, 12 ounces into the full fuel tank. Noticed IMMEDIATE improvement in acceleration and smooth idle. My Soul has 85,000 miles. I drove 200 miles and had a scheduled full synthetic oil change. Fast forward to 700 miles… no change on the dipstick!!! No oil loss. I have tried many “mechanic in can” products that only disappoint. This Sea Foam is the bomb!!! Saved me hundreds if not thousands in mechanics charges.

So I had a Polaris Outlaw 110 EFI, when started cold it kept shutting off and ran rough, mixed a can of this 50/50 with gas and ran it through and now it purrs like a kitten, definitely works

Excellent work

Wirkte Wunder bei meinem 42 Jahre altem Oldtimer Van. Nachdem die Jahre zuvor das Getriebe überholt , der Vergaser, Zündung, Kaltstart, AGR und vieles mehr für tausende Euro erneuert wurde und kaum Besserung brachten - wurde Anfang des Jahres 1,5 Flaschen Seafoam in den viertelvollen Tank gekippt und dann ca. 200 km gefahren. Das Seafoam scheint die Ventile des originalen ungeöffneten 42 Jahre alten 140.000 Meilen Motor so gut gereinigt und abgedichtet zu haben, dass der Van über die gewohnte Strecke über die Alpen nun 20-30km/h schneller ist (30km/h auf gerader Strecke, 20km/h Berg auf) und trotz der höheren Geschwindigkeit (nur) 19-21 Liter (Autogas) verbrauchte von zuvor 21 bis über 23 Liter. Also weniger Verbrauch und mehr Endgeschwindigkeit (ohne zwangsweise runterzuschalten und die Drehzahl ungesund hoch zu erhöhen). Hätte ich es nicht selbst probiert und genau mit App dokumentiert würde ich es nicht glauben. Ich hatte auch vor dem Ölwechsel ca. 200ml Seafoam in das Motoröl gegeben und bin 250km gefahren, konnte da jedoch keine besondere reinigende Wirkung feststellen. Das Motoröl war so sauber wie immer, vllt. weil es seit Jahren schon mit Ceratec Öl-Zusatz läuft (der auch fühlbar gut funktioniert verschiedenen Motoren) und der Motor deshalb sauber war. Bei neueren Autos konnte ich so eine gravierende Wirkung als Benzinzusatz nicht feststellen - aber vermute, dass es auch hier förderlich ist den Motor langfristig sauberer zu halten. Die Moral von der Geschichte: Wenn man ein schlecht laufendes Auto hat, lieber zuerst die 30€ inkl. Versand in Seafoam investieren, und erst wenn das nicht klappt mit dem Schrauben anfangen..... hätte in meinem Fall tausende Euro gespart. Als Ing. spät was dazu gelernt ;-)

I am from India, this product cost me 2.6k per bottle, which is a bit costly, but the performance of the product is very good, I used it on my Ashoka Leyland 12 wheel truck, I mixed this in engine oil, rough engine sound gone within 100km

discovered this stuff years ago for treating outboard motors...was hard to get hold of but now is easy through Amazon great for giving any engine a bit of a clean out without pulling it apart

Solo me llegò 1 bote, en la publicaciòn específica que es un paquete con 6 piezas!!
