Sea Foam SF-16 (SF1612EA) Motor Treatment 16 oz

GREAT product! I own a "mature" car with lower milage. However the low idle was off and slow, additionally learned that a Gas station provider (occasionally use) had been found to have water in their gas. After reading the reviews and learning many auto mechanics swear by Sea Foam, decided to give it a try. As a woman have experienced hype, un-necessary work etc through the years. I used a funnel to add Sea Foam to my gas tank. Wow! even on shorter trip, noticed a smoother performance. With longer driving seems to have helped the idle and running even smoother! Believe that with more use will see even better performance and hopefully better milage! Do Not Hesitate, you and your vehicle are worth it! Thank you!

I have an 07 Toyota Tacoma and it was very easy to use. Brought my truck back up to speed and seem to work pretty well. I hear nothing but great things about seafoam and I am pretty pleased with the quality of it. For the price I think it is well worth it. My truck runs like a dream.

Good stuff Works well

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.

Works good.

This stuff is amazing. Did not know I could buy this at Walmart. Probably will not buy online again just because I can go pick it up near by,

I put a can into each of our cars that both have between 135-145,000 miles based on the advice of a friend. Both vehicles showed noticeable engine improvement and better gas mileage. We will be adding to a tank of gas every 3-6 months. Great product!

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!!
