Feel better putting this in vehicles gas we don't use as much, this plus ethanol-free gas should stay good for many months, maybe longer.

This is a must have especially if you own a boat. I bought a boat for my friend who said it stalled once in a while. I said STEVE dont worry about it. Ill have it fixed. I fixed it with the PRI. When you use it for the first time, it should run the motor for 45 minutes. Running about 4000 RPMs.

ok here is what I've read about this product- and my experience. PRI-G (and PRI-D) both are an additive that restores and fixes gas to keep it from going bad, and to also recover it if it has already gone bad. when I mean go bad I mean gas with corn (ethanol) turns to varnish...it becomes a sludge, that clogs carburetors, and eats rubber away -cheap gas is bad news for small engines, and storage of small machines. so I picked this up to keep my generator running while I store about 10 gallons of gas in it, and have propane for it also. I started using PRI-G in my other machines (zero turn/leaf vacuum, push mower, snow blower and my quad (that I use maybe once a month/or to plow snow over winter) -since some of these items don't get started every month, it might be two or three months before I'll fire them up and give them a pull. battery powered DP leaf vacuum starts on the first button press I've only ran it about 10 hrs, but it's been sitting over the winter (I start it monthly) the generator gets started every month, and usually in our area of NEPA...We have dead ash trees so just about every storm I do get a chance to use the generator. Outages are kind of common where I live and that was my main reason for buying this PRI-G additive. I know it's likely with in about 2.5 days I'd be out of 10 gallons of gas, my main concern was will the gas be good when I finally need it? Sadly I've seen lots of lawn mowers in my area be stored over winter with gas in the carb, and those machines don't run until the carb is cleaned or replaced. That being said PRI-G/PRI-D (for diesel BTW) have a place if you have a concern about storing gas and having your machine start and actually run when you need it. PRI-G really settles that concern and that is why I believe it's worth the money as an additive. Thanks for reading my review! Have a good one!

This treats much more fuel per container than some other gas treatment products out there. I use it for small engines and vehicles I dont dived often, so far it seems to do its job!

This gas stabilizer is fantastic! I always add it to the big fuel tank on my homestead and gas stays volatile. My pickup always runs great and all of the small engines fire right up.
