i throw in 3.5 oz few hundred miles before an oil change and it does really help all the older junky oil get purged from my crankshaft. i can tell the difference visually looking onto the crankshaft and when i change my oil.i have 70k on my car and should of started doing this sooner.i do have a gdi (gasoline direct injection.) so putting into your tank doesn't do much (anything for valves) but putting it into the crankshaft as directed is amazing.

not a single product works as well as this does. I put it in a 2005 Polaris I bought used, after a tank of gas and seafoam the carb cleaned right up and the ATV runs like new, use this in all my vehicles even a tad in my chainsaw

great product and excellent price

Works good.

Had a small tap valve, dropped a can of this in the oil and just like that it smoothed out. I not only use this in the gas but now I put a can in the oil about 500 miles before I change it.

Good product

Seafoam is the best fuel treatment, hands down. Buy in bulk and save some cash.
