High Mileage Fuel & Oil Treatment, 16 oz, Pack of 1

This is by far the best product to keep your engine in shape and lasting a long time.

My truck runs much smoother with this in! I put it in every second full tank!

I have been using this product for years.It has never disappointed and has always given me better gas mileage than e.P.A estimates

Seafoam is seafoam. Cleans out my truck and stores well. Always easy to use and less expensive than replacing the catalytic converter haha. Functions well, doesn’t leak that I can tell and looks good.

Great for older high mileage engines.

Started using Seafoam about a year ago when my 2016 Toyota Camry was burning oil. I was using about a quart of oil every 1200 miles. I started putting 5 oz in the crankcase and the remainder of the bottle in the gas tank 200 miles before every 5000 mile oil change. After two treatments, the oil consumption rate is about a quart every 6000 plus miles. Reduced engine noise and improved performance. The Camry is going on 340,000 miles with all original parts. It works for me.

I utilized this additive in my engine oil 200 miles before my scheduled oil change. This is on a Toyota tundra with a 5.7 L V8. I added the correct amount to the engine oil and drove 200 highway miles and then scheduled my oil change with a proper supplies. When I pulled out the Oil filter and took a closer look I saw an awful lot of black specs. It may be hard to tell in the pictures that I have attached but upon closer expections, you will see little black dots. When I would grab those and rub them between my fingers they would smear , like carbon deposits that had been removed. There were no metallic flakes or hard bits that I felt. After using this product, I noticed that the vehicle idles smoother, accelerates and runs smoother, and I do believe that it helped clean out some carbon buildup on my high mileage truck. I’ve been a believer of seafoam products in the gas and I am now a believer of seafoam products in the oil. If you follow the manufacturers directions, I would assume that you would be happy with the results as well.

I use this on all my vehicles because it works. I also put a little in the gas for my 2-stroke tools, and they keep on running. My truck has 235,000 miles on it and runs like a champ.

Nothing work

I heard it was the product to use to clean the inners of my car. It seems like it does the job.

Buy it!

I poured half in my oil tank and half into my fuel tank and it made my engine run smoother

Appears to be strong suff. Will not disappoint.
