Sea Foam High Mileage Motor Treatment HM16, 16 oz, Pack of 1, Silver

Adding into an almost empty diesel tank and then filling up seems to make a real difference to engine performance - in my opinion

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

Seems to do what it says on the tin as it cleaned the gunk off the rockers and the cover

Appears to be strong suff. Will not disappoint.

Nothing work

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

Excellent results

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.

The seafoam product worked very quickly huge performance increase ...Worth the money
