Seafoam SF16 review
Brilliant stuff, my outboard was groggy carb needed cleaning, engine needed a strip down, but decided to try seafoam to see it did what it said it did,
After an hour using the product as directed the engine was purring like a kitten, just wow, truly unreal, forget about redex or alternatives stick with this you can't go wrongRead full review...

The best..
Not sure this will improve a new motor, but anything with a few miles on it will be greatly enhanced.. Lost count of the number of lawnmowers I have 'rescued' with seafoam.. With a can I put half in the fuel tank, a quarter into the oil (a week before an oil change) and the remainder goes straight into the breater pipe into the engine.. Lots of white smoke and 5 mins later the engine breathes easier and seems to recover power and smooth running
Wonderfull stuff..!Read full review...

Good pre oil change
Engine seems to run quieter having used it in the oil before an oil change.Not sure if any difference to the fuel system

Excellent product
Great product, use it in petrol tank and oil tank, cleans jets etc, used it to clean lambda sensor as well, I also use it for my 3 outboard engines, works a treat.

It works. Excellent.
My chainsaw had a blocked carb and had not run for 15 years. I put some of this neat in fuel tank and down air intake and left for 24 hours with spark plug removed. Then shook it all out, filled with fresh fuel and it fired up first time. Excellent product that really works.Read full review...

Sea Foam great product.
Sea Foam does just what it says on the can, can't fault it.

Obvious difference afterwards
I'm really pleased with this. My 1987 VW T3, 1.9 litre water-cooled is much smoother and quieter and feels noticeably more peppy. I used it all as a petrol additive, adding almost the whole can to half a tank. Highly recommended. Read full review...

Saved bearings in Yamaha R1
Coolant got into oil on a Yamaha R1 which can destroy bearings - flushed it through with new oil and filter a few times - milky oil still showed up - so researched and bought this Sea Foam adding this product to a couple of more flushes - this done the job - no more milky oil :)
Bike has since done 1500 miles with no issues
Top-tip: whilst doing these oil flushes let bike warm up on idle - then run engine for 20mins each time gently revving to a maximum of 2000 rpm (do not exceed this limit while carrying out this procedure no matter how tempting it is ). This should be done whilst bike is static. Good luck !Read full review...

Magic in a can....
I have a 2000 Peugeot Boxer that was particularly smoky on start up, had a rough idle and smoked on full throttle. A can of Seafoam in the tank and a couple of spirited drives later and all of these ailments had gone. I have bought another can so that I can continue to dose the tank..Read full review...
