Review: All good, long time user here - I have been using STA-BiL for almost 2 decades, I always put a little bit more to treat the gas, no issue with gas that I got in the fall, and using now in late spring. I usually don't use gas longer than 6 months — old gas go into my car. No issue with clogged carburetor in my snowblower, lawnmower, hedger and string trimer. i empty the tank as much as i can for the snowblower and don't fire it up till a year later. No rust in the gas tank either. Good insurance to have against needless repairs and tinkering.

Good product. Allows for easier and quicker starts

### ⭐⭐⭐⭐⭐ More get up and go!! Better mpg to boot.
*by N***K on November 17, 2011*

I bought this, the first time, by accident for my lawnmower. Once I realized what it was I decided not to use it in the lawnmower, but dump it in my car. I really didn't expect anything. Boy was I wrong!! At first, obviously, there was little change, but after 30 minutes or so I pulled out from a side street onto a main road and was caught completely by surprise when my car took off like greased lightening!! Much stronger than I was normally accustomed to. My car has a 6.1L Hemi, so it's a big engine with lots of power to begin with (425hp). The difference in power and responsiveness from the engine after adding this stuff was simply incredible. That's not the best part though. The biggest surprise (to me) was the increase in gas mileage. I normally run between 13.5 and 14.0 mpg around town and 20.0 to 22.0 on the highway. I"ve not had a chance to check my highway mileage, but around town I'm now getting between 14.8 and 16.5!! Not a big deal you say? Think about it. The smallest increase is almost 10%, the largest is nearly 22%. Okay, in different terms. I have to run premium fuel, which is real close to $4/gal. Let's say the increase is only 1 mpg. Over the course of one tank of fuel (16 gals), that is nearly a gallon of gas saved. Total savings. $4. It nearly pays for itself, reduces the amount of fuel I burn, thus less emissions, and it gives me more power. Can't argue that logic! Better yet, using the best case scenario of 3 mpg increase, the savings really adds up. 3 mpg * 16 gals = 48 miles. 48 miles / 16 mpg = 3 gals. 3 gals * $4 = $12. This stuff is now saving me money. On average, I find the savings I receive from using this stuff far exceeds its cost. Yes I have ran a tank of gas through the car w/o using this product since, and yes I noticed a difference, both mileage and power. My next experiment is to put it in the minivan. Maybe I'll report back again then. If you would have told me this stuff would make a difference I would have called it snake oil. All I can say is, go buy one bottle and you WILL notice a difference. You'll pay about $8/bottle at your local parts store though.
