    • Dependability
Style: Truck & SUV Motor Treatment
Was recommended by my mechanic for my 1999 Motorhome with almost 100,000 miles on it, The idle was a little ruff and slow, I put four cans in my 75-gallon tank after driving about 200 miles it's running much better.

    • Gets the crud out
Style: Truck & SUV Motor Treatment
I've been using seafoam for years and it always gets the crud out. My wife's SUV was throwing a code for bad O2 sensor and I had replaced it about a year before. One can of Seafoam and the light went off. I put a can in every 6 months or so and the sensor stays clean and truck runs fine.

    • Worked for me
Style: Truck & SUV Motor Treatment
I have a 2017 Armada, with exactly 100,00 miles on it. It had developed a stutter , or misses in the engine, during initial excelleration. I installed new spark plugs which did not help. Next I began using the high mileage Seafoam. That did not clear up the missing immediately, but it slowly cleared it up after each additional application of high mileage Seafoam. It took numerous applications and approximately $100 of Seafoam, but it did clear up the problem completely. I'm happy, believing a mechanic would have cost me a lot more. My Armada is now running perfectly. ... show more

    • I would fill up my whole gas tank with Seafoam if I could!
Style: Truck & SUV Motor Treatment
Excellent product when added to your fuel after filling up. I can always tell a difference in how my vehicle drives after I use this product. It's like a magic elixir for your car similar to how occasional and moderate consumption of alcohol helps to lubricate the human soul.

    • 2mpg gain
Style: Truck & SUV Motor Treatment
Added 4oz to my engine and the rest into my 23gallon fuel tank. I calculated my mpg manually before and after each refuel. Measured 4 fill ups prior to Seafoam, average 13mpg on my Audi Q7. Measured 4 fill ups after treatment, average 15mpg. Not bad.

Amazon seems to be the cheapest place around for Sea Foam. Not sure how well it works, I've never torn an engine apart that I've been running it in.

Style: Truck & SUV Motor Treatment
Great fuel and crankcase conditioner. My 2004 Tundra runs smoother and gets better mileage. I added 6 ounces to the crankcase (6.5 court capacity) ahead of my next oil change to help clean the internals. Already noticing a difference...
