Fixed a rough idle completely
My old Jeep was idling rough. Added Sea Foam to the gas tank and ran it through the oil. Idle is smooth again. This stuff is real.

Cleans carburetors like nothing else
Used on my lawn mower that sat all winter. Started on first pull after treating. Classic product that delivers every time.
