I use this for my oil and gas and it does wonders for my vehicle.

I purchased a used Dodge Wheelchair van in NJ for my sister that lives in Virginia. The van had sat and not used for 6 months with half a gallon of gas in the tank. I thought the gas was probably bad and the ethonal had probably absorbed water but I just filled it up with premium gas and took it to Va. I made it to just southe of Washington DC, the worst traffic on the east cost at rush hour and the Van started stalling and cutting off in 5 lanes of stop and go traffic. I had to keep one foot on the brake and the other on the gas to keep it running. I pulled off at the first exit I came to, went over to Rt. 1 and found an autoparts store. I told the older man at the store what was happening and out of the couple dozen cans of fuel treatment on the shelf, he told me to get a couple cans of SeaFoam. I put one can in at the auto shop, drove a mile or so down Rt. 1 to fill up the gas tank to full and before I got to the gas station it started running without me having to keep my foot on the gas when I stopped or slowed down. I added enough gas to fill it up to full, added the second can and before I could get back out on interstate 95 it was running normal. I made it to my destination without any more problems but told my sisters husband that he may have to get some work done if it starts cutting out on him but he never had another fuel problem again with the van years later. Great stuff, would not believe it if I had not lived it! Now I use it in ALL of my 4 stroke and 2 stroke motors. Still running a 1990 Johnson 225 and still running strong, I'm sure it helps keep two stroke oil carbon down. Highly recommend!

Works as advertised.

Works amazingly great for routine maintenance

Wonderful stuff highly recommend

Great product

I use it in anything that takes gas. I also put the required amount in my 1990 buick during a oil change and cylinder walls look great. I recommend it

Using this on a four barrel carburetor 390 ford engine. Seems to improve engine idling and overall performance.

This is the best on the market.

i use this for fuel injuction clean and gas treatment every 3000 miles

Use this frequently. Cars, tractor and boat.

it works great in getting engines started and running

Great product been using for years

I believe that it works, so it works.

This cleans your engine really good.Don't need to use very often. Maybe once per year. You will notice the difference after running Sea foam through your car.

My mower was stalling at half tank of gas I add some of the seafoam to the gas tank and it runs till I run out of gas now.

Great product cheapest ive found it. Was about 4.00 cheaper than the auto parts store. Made my car a lot peppier in acceleration.

Great for reviving winterized lawn mowers. seriously this stuff works miracles.

I have used Seafoam on small engines for gas treatment and winter storage. Never really thought about using it to clean an auto engine. My 2002 car with almost 200,000 miles had LOUD motor noises that would last until engine warmed up. 5 minutes or more is polite. I knew it said for ALL engines so I looked it up. 1 bottle in gas tank and 6 ounces direct in oil. (Note: I did not use spray for intake) Wiped my hands off and started car. 15 seconds the knocks and rattles were all but GONE! I let it run at idle for 5 minutes then would rev engine off and on to 2000 - 2500 RPMs next 5 minutes. Motor now has more power, no motor knocks or tics, no exhaust smoke like prior. Now I had changed oil less than 300 miles prior to this and oil was still nice and tan. I have drove just under 300 miles since. Oil was so dirty it looked like it had never been changed! I did notice a rough idle after so I used the intake spray. Smoked bad, smelled bad but now the oil motor is purring! I was not sure what to expect but from now on, I am adding 1oz per quart of oil (to oil) after each oil change. I have tried other cleaners but compared to Seafoam, I wasted my money on those.Seafoam - I am beyond impressed!!!!!!!

I purchased this fuel additive on recommendation from a friend. He swears by this product.I have not noticed and differences in mileage or performance.
