One of the Few Fuel Additives I Keep Buying
Color: Pack of 2
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.

Mechanic Recommends Sea Foam -- Best Gas Treatment for All Engines
Color: Pack of 1
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 swear by Seafoam, especially for small engines
Color: 3 Pack
I swear by Seafoam. It has really helped out my small engines, especially the 2 strokes and ones that sit around for long periods of time like my leaf blower and roto tiller. After I started adding Seafoam every time I get fuel I have had zero starting issues. They can sit all year and they will still start right up. In my car/trucks with higher miles I've used it to clean out the crankcase with great results. I add a can to the oil right before doing an oil change. I add a can then take a short drive(10 miles) to make sure the oil is up to operating temperature and change the oil once I get home. It does a good job cleaning any sludge out of the pan and the new oil stays looking fresh/clean way longer.

It's Sea Foam (but not green)

What is there to say? If you're buying Sea Foam, you know what it is and what it does, and you're probably going to continue buying it. It's great stuff.
