Sea Foaming my mazda pickup 1994 with 137,000 miles on it. 1/3 in vaccume line, 1/3 in oil, 1/3 in gas tank.
Took it for a 20 mile drive afterward....really made a difference. Oil change right after the long drive.
PS...ANYONE ELSE NOTICE THE SMOKE RINGS??? LOL
So it does work? I own a classic that I want to try it in but I heard it can screw up your engine too
