E-10 Protection


I use this to stabilize and protect my E-10 gasoline during winter storage.I have done this for years and also use another version (EZorb) during the season at each fillip and it seems to work as planned.

Store-N-Start is the most trusted stabilizer product I've ever used. For decades I've used it in our I.O. boats.I once had to layup our 25' V8 Mercruiser powered boat with a 90 gallon tank full of fuel for three years. When at last I was able to use it again I was so skeptical that I had a tank full of "bad gas" that I left it on the trailer and backed it into the water to see if it would run. Fired right up like it'd just been shut down and ran just fine as I used that tank full up, to my delight. I was totally convinced this product works after a three year test like that. Store-N-Start always works great in our snowmobiles to prevent "bad gas" carb. issues over Summer storage too. I realize Marine or RV gas as well as Premium pump gasoline is ethanol free but I use Store-N-Start in my 6 gal. storage can of E-10 pump regular used in my lawn tractor too. It stops the faze separation that so commonly happens with stored ethanol fuel. Any seasonally used engine that you've put ethanol gasoline into, outboard motors, mowers, leaf blowers and the like deserve Store-N-Start. My only complaint is finding a local retailer, so I buy it by the gallon to make sure I don't run out. In my book the security in knowing you've protected your expensive equipment is worth buying the best there is in fuel stabilizers. . .

I use it and it works


I always store a few gallons of gas over the winter and have had good results with the MDR stabilizer. With the high cost of gas I can't afford to not preserve every drop. Plus putting stale gas into your equipment (lawnmowers, motorcycles, etc.) can be a costly mistake.
