What it does

One bottle guards, the other repairs. Ethanol Shield Marine keeps fresh fuel fresh through the layup, while Mechanic In A Bottle goes after what old fuel left behind — varnish, carbon, gummed carburetors and injectors — in gas or diesel engines. Together they cover both ends of the season: the machine you stored right, and the one you didn't.

  • Ethanol Shield Marine 24 oz — stabilizer and preservative for the layup
  • Mechanic In A Bottle 24 oz — synthetic cleaner for gas and diesel engines
  • Cleans injectors, removes varnish and carbon, revitalizes old fuel
  • Reconditions rubber gaskets and seals, restores lost lubrication
  • Covers 2-cycle, 4-cycle and diesel — boats, mowers, tractors, trucks

Crew notes on this bottle

★★★★★THis stuff is the BEST
THis stuff is just magic!! Watched a review on Chickanic you tube channel where she tested both items, and the results were conclusive... the mechanic in a bottle started engines which previously didnt start. If you have doubts, go to her youtube channel...
