Sea Foam Motor Treatment Fuel & Oil Additive, SF16, 16 oz, Pack of 4

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.

Just what I ordered shipping was quick

As listed

We use this in our vehicle gas tanks every few months to keep the injectors clean and also in some small engines to keep the carburetors clean. The bulk package is a much better price than anything in the local stores.

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.

I use this for preventative mtc, I'm not sure it does anything, but my car has 70,000 miles on it, with no major engine troubles yet. Once or twice a year, I'll put a couple cans in the gas tank before a long road trip to help keep the fuel system clean, and about a week before every oil change I pour half a can into my engine oil. I believe it helps keep my fuel system, and internal moving parts clean, but I don't have x-ray vision, so I can't really tell.

Restoring old machines,I often find engines that have not been treated well, and at some point they all usually need some of this SeaFoam to "get the gunk out".Would I pour it into every engine all the time? No, I buy quality fuel, but occasionally an engine will show signs of fading and SeaFoam usually brings it back to its normal condition.
