Works well. How well. Well let me tell ya. This stuff brought back to life a twenty year old edger trimmer and made run like new. No shed.

This product is very good. A friend of mine who knows a lot about aviation told me about the issues they were having with ethanol in their fuels and that the same is true with today's E10 in autos. Since I have an older vehicle, the ECU is not programmed for running ethanol blended fuels, 360 performance helps combat this by doing two things. 1, it helps counter the corrosive properties of the alcohol in the fuel lines and injector o rings. 2, it alters the ethanol chemically to behave more like 100% gasoline. (I wish I knew how it does this.) My car runs smoother and starts better when hot, it use to not do this. I keep my car in top nick, and tuned up on a regular basis, so there is no neglect outside of regular issues you might have with a daily driver.. These properties are essential for lawn equipment, dirt bikes, motorcycles, two stroke engines and earlier obd I & II vehicles. The E10 blends tend to spoil quickly and this will help that as well. I wish I had this stuff 10 years ago. In CA, they started a 3% blend in 2003, then went to a 5% in 2005, then a 7% blend in 2007 to a 10% E10 in 2010. Newer cars can handle a 15% but none earlier than 2007, so the E10 mandate is a compromise. The only way to buy ethanol free fuel is to buy race gas at a very high price point, the Stabil 360 Performance is an economical additive to combat the ethanol properties. I don't know if this affects the octane rating after adding. I really started to think about this topic: Out of every 10 gallons of fuel i put into my car, 1 gallon is ethanol. No wonder my car was running like doo doo!

My mower runs better than it has in years with this in the gas. I wasn't expecting that, so it's a nice surprise. I was just expecting a fuel stabilizer.

I used this in my riding mower before I stored it for winter. The mower sat for about 5 months with the same gas(PLUS this stuff) and it started right up and ran just as good as ever.

Fuel Stabilizer, works good as far as I know, only time will tell, use it in two of my stored vehicles.
