Phan 52 #1 Posted 10 hours ago Hey! I want to share the YouTube - testing: Ethanol shiel, Mechinic in, and Sea Foam. For a few years, I have used Sea Foam for WH 312, C160, Auto 12 - it seems to improve a bit on the engine. I've also used Sea Form for 2003 Highlander (it does help a lot!) and 2016 F160. Here the tests show - Any comments for debats? 1 Share this post Link to post Share on other sites
8ntruck 8,682 #2 Posted 9 hours ago Interesting tests. Not sure how relevant they are to how the product acts when run through an engine. I treat my rec fuel with Seafoam at 8oz per 5 gallons of gas. Seems to work OK. Some balky engines it seems to help, others, not so much. After seeing this, I think I'll get some Ethanol Shield or Mechanic in a Bottle to run in Pack Rat, the Allis Chalmers B-110. It has a backfiring issue on throttle down - particularly when it is cold. I'm kind of wondering how much carbon build up it has. Yes, I know I should pull the head and take a look. Maybe I'll get to that this summer. Share this post Link to post Share on other sites
