I heard about this on the Bronco boards and tried it. About 1/3 can through the brake booster hose into the intake, not booster, she'll smoke like a banshee for a few minutes, then clear up. I now run a can through the fuel tanks every 10,000 miles or so. I've gained about 1.6 mpg which shows it was dirty in the first place.
Where can i get a can of that Sea-Foam. Also can i run it threw a 1988 F350 460??
Thanks
