Ethanol Shield Fuel Stabilizer, 24 oz (2 Pack)

This is one of the best products on the market today. Keeps gas fresh, and maintains o rings and seals. Keeps them soft.

Works as described

I recently switched to this brand of fuel stabilizer, so I can NOT provide a long term assessment of its effectiveness, yet. But, I HAVE used this same company's other product, "Mechanic in a Bottle", & I know for sure that it does a great job of softening Rubber parts. So -- maybe this company can be trusted? The main reason I bought this particular brand of Stabilizer, is that it seems to do a good job of mixing with water in the gas. The YouTube channel "Chicanic" made some compelling arguments for using this product to mix with & burn out water in gas. With today's Ethanol gasoline, that can be a very important quality. I have an old hunting truck that does not get much use -- the gas sits in the tank for2-3 months, and the Ethanol WILL soak up water from the air -- East Texas is very humid. So, I'm adding this brand of Stabilizer to the tank to mix with the water at the bottom of the tank, so it can get burned up. I shoulda done this years ago -- I've already had to replace the metal gas tank once, because it rusted out at the bottom, where the water collects.

Seems to be a good product

I had two mowers with old fuel that would not run. I used as directed, drain the fuel system, added Ethanol Shield Fuel Stabilizer for 24 hours then drained and added new fuel. All in all it worked pretty good, I all take 50/50 odds of not have to tear a carburetor apart any day. Results were 50/50 aswell one ran great and one got a new carb. I Ordered after seeing (Chickanic) YouTube review.
