Everyone’s dealt with ethanol at this point, and Teleflex marine has just come out with a new way to fight the problems this stuff creates: Sierra eGuard. If you haven’t been using an ethanol additive (like Startron or Biobor) chances are you’ve had issues with phase separation, gum, and poor performance - and these are the things eGuard is supposed to take care of.

Teleflex claims that eGuard removes existing gum and carbon build-ups, as well as preventing their formation. It also disburses water particles in the fuel, preventing phase separation and allowing it to be vaporized in the combustion chamber. It’s supposed to keep your fuel in good shape for up to a full year, as well as boosting the octane of old fuel you treat.

One ounce of eGuard takes care of 10 gallons of fuel, and it comes in 32 and eight ounce bottles. Sierra also makes fuel stabilizer, so this type of product isn’t 100-percent new to these guys, and they ought to know what they’re doing. But, will eGuard really do the trick when it comes to combating ethanol? I’m going to find out for sure. My cantankerous lawn mower is super-sensitive to ethanol, and never runs right unless I treat my fuel with one of the ethanol-specific products. So I’ve set a gas can aside to age, with eGuard in it. After three months I’ll fuel the mower with it, see what happens, and report back to you here. Stay tuned!
