None. Mineral spirits. PRI-G if I felt the need to use an officially licensed product.
EXPY will be along shortly to insult you, fear not. |

The fact that some generator manufacturers recommend using a fuel stabilizer - or include a small bottle of it in the generator shipping box - should tell you something.
There aren't a lot of fuel additives on the market that claim to be stabilizers. IMO, the few that do are worthwhile. |

Regular Stabil worked fine until we couldn't get anything but ethanol fuel here.
Marine Stabil has been working fine in the ethanol stuff, using an ounce per 5 gallon can, the gas has stayed good for over 12 months, haven't tested longer. The ethanol fuel, if left untreated, seems to suck moisture out of the air. I'm in Maine, different climates may find other treatments work better. YMMV!! Regards, Eric |

Quote HistoryQuoted: ... The ethanol fuel, if left untreated, seems to suck moisture out of the air. ... Ethanol and other alchohols are hygroscopic, and will absorb moisture from the air. E.g., HEET gas line deicer is composed primarily of isopropanol or methanol, depending on which version you get. They work by absorbing moisture that's made its way into your fuel system. |

I marked other, my favorite fuel stabilizer for long term storage is proper storage (sealed, pressure containing vessel that won't leak and doesn't have to be opened frequently).

Sta Bil is all I have used, so that's how I voted. I can actually find it on the store shelves, so that helps.
I've used it for a few years to store gasoline, usually for a year, and have had no problems. Doesn't prove anything, but that's my experience. I use the common five gallon plastic cans, which are kept in my barn. |

I did a bit of research on this....
I do not put anything in the gas but I do have a bottle of Pri-G to use as a gas 'Restorer' if a long term situation occurs where the fuel sits for years. BTW- I called Pri-G and was told the shelf life of an unopened bottle of Pri-G is indefinite. Opened - worsted case 1 yr. |

How can a few capfuls of mineral spirits 'restore' important volatile fuel fractions lost from fuel that has sat in a leaky fuel can for years? Also, how does the 'mineral spirits' ---that are what the bulk of Pri-G is... go bad, even if the bottle were opened and reclosed???? Would you post a link to your research? ETA, I've had opened 1 gallon cans of mineral spirits sitting on the shelf for 10+ years and it's just fine!

Can anyone post a link to or a copy of the current MSDS for Pri-G? The only one I could find was form 1998 and looked like a bad photocopy. You would think the manufacturer would have this linked on their product website.

I really don't get too worked up about this (frequent) topic.
My stored gas is for my generator, which is for my water well. I don't plan to maintain a typical American road warrior life style on stored fuel. If the supply is disrupted long term, I'll use what I have as wisely as I can, and when it's gone, it's gone. Premium gas is the best bet for the small engines IMO, regardless of what you add, if anything. |

I will say that I have far fewer problems cranking up generators when I use Stabil Marine than when I didn't. Some of the gennys I have don't have a good fuel shutoff so they surge, start to die, pull enough vacuum to suck fuel thru the valve, then surge some more, start to die, repeat. So, on those cheapo gennys, I can't really drain the carb effectively unless I yank the fuel line or run the tank dry. I'm a little lazy in that I'd rather use a stabilizer and keep gas in the genny so that all I have to do is start it than have to go find gas, fill it up, pull a few times until gas starts flowing again, etc., especially if I'm outside freezing my a$$ off in the dark because the power went out at 2am.
Just my $0.02. |

I can tell you what I did with my diesel, but I do not store much gas at all, only diesel.
Back in 1996 or 97, I can't remember, I bought 3,500 gallons of off road diesel for my gen set. It was around $0.63 or $0.68 a gallon then, again I can't remember. I had several large tanks, but I also had eight 55 gallon drums that I filled up as well. In four of them I treated with PRI-D and four I did nothing with. All the tanks were filled to where very very little air space was left in them at all, and all bungs and plugs were removed and cleaned, and sealed. The main bung I sealed with a urethane caulk as I didn't trust that cheesy rubber gasket to hold any serious length of time. Long story short, in 2013 I opened up the drums that were 100% diesel and NO additives at all, and all four drums, the fuel was in perfect shape and the pink was the exact same color as fuel a bought earlier that day to compare it to. It ran in the gen set for several hours with no trouble at all, before I shut it down. Again, this is diesel and not gasoline. |

PRI links
FAQs PRI G fuel stability info PRI G MSDS Other reading on amines More light reading on fuel additives More reading While I am NOT a chemist, from the links above, there does seem to be something to PRI's claims. From their MSDS, it does appear that something similar to mineral spirits is a fairly large percentage of the content. However, there are also other chemicals in PRI G as well that do appear to be commonly known to be effective at slowing fuel oxidization. So, if you are using PRI G, you are clearly not JUST putting mineral spirits in your fuel as some here love to claim. It seems quite possible, from the above links, that some of the chemicals in PRI G could well be effective at slowing the deterioration rate of gasoline. Fuel makers already add a number of chemicals to our fuels such as various detergents and such. And, fuel manufacturers have to find a balance of the right blend of additives to run our vehicles properly and at the same time, minimize cost to the fuel producer. So, adding additional chemicals COULD enhance the chemicals already in our fuel. Sounds like PRI has done research. I doubt that they just dump mineral spirits in a bottle and sell it unsuspecting idiots. From the links above, there does appear to be something to their claims but it would probably take a chemist to make sense of it all....and then us normal people probably still would not understand it! Regardless, the number 1 way to keep your fuel fresh is to keep it well sealed. |

From endless DRY reading in some of the links I posted above, it does appear to me that some of the components in PRI G are useful as fuel preservatives. Now, I have no clue what ratio you would need to use of the various chemicals in order for them to be effective so I have no idea if PRI G, when used as directed, contains enough chemicals to actually do what it claims. But, it does appear that PRI has researched their formulation aside from just selling mineral spirits to idiots as some here have postulated. |

Stopped using stabilizer 5 years ago.. No issues since. Motorcycles sit all winter with straight gasoline , and start right up. Chainsaws all start right up after sitting several months with mixed gas. Generators usually get test run 3 or 4 times per year, and always start right up.
