Great product and great price!

I use it in fuel system every few months to help keep my vehicle engine running smoothly. I add a little to my gas cans for my lawn mowers and my side by side too. Planning on adding to my oil before my next oil change to help boost performance. Couple of cans dented from shipping, but no leaks! Its not food so im not going to return a dented can.

Stopped the shaking

Works way better than Lucas. Our car was shaking while idling because it's not driven enough. We tried Lucas for awhile, but hardly any improvement. Seafoam high mileage cleaned it out so it doesn't shake anymore. It's more expensive since it doesn't come in a gallon like Lucas, but well worth it.

100k plus miles?....you need this.

If your car has over 100k miles on it, you need to put this in your gas tank prior each fillup. Need proof. Go to youtube and watch Farm Projects review of fuel additives. See for yourself.
