Will this product give me any benefit?** A: It will prolong the "Freshness of the gas either way " **Q: what is the difference between this product, Stable 22275 360 and Stable 22284 360? 22284 has less product and costs more.** A: Good question. If you go to the manufactures site, goldeagle dot com, you won't find the 22284 product, just the 22264 product. **Q: Can be this used in 2004 Lexus ES330, general gas not ethanol fuel.** A: Uh.. general gas for vehicle has ethanol. Only fuel you find without ethanol is on some boat gas station for boats and maybe some race track gas station. I doubt you are in either category. So yea, your fuel has ethanol and this will helps it if you don't drive it often. If you drive it and gas gets depleted in a week, then this doesnt do much. You maybe just want some fuel cleaner like the Chevron Bottle to keep your fuel injectors clean instead. **Q: Can this be used in the gas for a Mercury 90 outboard motor ?** A: Absolutely. It can be used on any gasoline engine. It works on non-ethanol and 2-cycle fuel as well. ## Customer Reviews ### ⭐⭐⭐⭐⭐ All good, long time user here *by N***C on May 20, 2026* 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.

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. ## Frequently Bought Together - STA-BIL In-Season Protection Fuel System Treatment | Full Protection Fuel System Cleaner, Injector Cleaner, Increases MPG, Prevents Corrosion, 4 Fl.
