You just have to ask yourself if the cost savings of ethanol gas is worth the risk of having a problem when you need it. Seems like it doesn’t take much for a carburetor to fail you. Also consider this… non-ethanol gas has more BTU energy than ethanol gas. So technically your generator engine (running non-ethanol gas) would produce maximum power with better fuel economy.
Honda EU7000is Rust Issue
As a matter of background, I had my previous EU7000 for about 3 1/2 years and decided to sell it to upgrade to the current version with Bluetooth, etc. My previous unit was in pristine shape and no rust whatsoever and always kept in garage. I've had my current unit for just over 7 months. My neighbor also has the newer version, same unit but purchased about 1 year ago. When my neighbor asked for help with her unit, I also helped fill the gas tank. When removing the gas cap, there was a lot of rust on the fuel tank's rim where the cap connects. I thought that was very unusual for a relatively new unit and one kept in her garage. Also disappointed as I recommended the Honda unit to her. Then due to the recent storm, I too added a few ounces of fuel to the top-off level recommended in manual and noted the beginning of pitting (the beginning of rust) in the identical location of my neighbor's unit - the pitting/rust is under where the gas cap gasket seats to the fuel tank. Cap appears to seat firmly and snug in place so I don't think it's a bad gasket. My unit is also stored in the garage and partially air conditioned from house. I am totally perplexed as my previous unit didn't have any rust at all, was stored in identical location and have always used the suggested E0 fuel. Are there others that have the new version Honda EU7000is for over 7 months that have the same rust problem beginning? I'll get a photo of my neighbor's unit that will show terrible rust while mine appears to just be starting. I did coat the area with motor oil to hopefully slow down the rust.

Taryl tested "everything", including "Mechanic in a Bottle", all produced varying levels of corrosion after months of storage and E87 vs E93 showed "regular E87" worked just fine. The key to E0 (VP Racing Fuel) was that although there was significant evaporation, the bowl and the main jet, emulsion tube had no corrosion, no impurities, remained clean.
Reason I use "Yamaha ACC-FSTAB-PL-32 Fuel Stabilizer & Conditioner" --- which BTW, is not quite same as "Yamalube Fuel Conditioner" --- is the direct exposure of marine engines to ocean water plus I buy it in bulk so not very expensive.
E0 fuel is used in our generators, chippers, lawn mowers, chain saws, concrete cutters, trimmers and also in 2 cycle engines which have a 40:1 or 50:1 fuel
il mix. Have had several warehoused Echo and Stihl arborist saws which started up fine after 2 years -- also stored in high humidity.
For Yamaha ACC-FSTAB-PL-32 -- 1 ounce treats 3 gallons for short storage or using right away, otherwise use 1 ounce per gal if storing fuel for 6-8 weeks or greater. So ratio of mix is either 1:3 or 1:1

Honda's part site shows a new tank at $65 if you decide to replace it. PartsPak lists it for $42. Not too bad for a new fuel tank, but I think you are approaching it the best way for now using Honda's warranty. It should not be rusting.

Was somewhat disappointed that the additives Taryl tested proved useless but good I don't need to purchase more of that snake oil.Taryl tested "everything", including "Mechanic in a Bottle", all produced varying levels of corrosion after months of storage and E87 vs E93 showed "regular E87" worked just fine.

Did Taryl test the Yamaha product mentioned above as I didn't see it? Because of Taryl's tests and all of them worthless, is there a test done somewhere that shows the effectiveness of the Yamaha item? And thanks for all that info, very informing and not wasting money on worthless products. I thought that Taryl's testing was quite thorough and not biased.The problem is that Honda is already referring me to the dealer. And the dealer doesn't seem inclined to believe something other than humidity is the problem; they just don't get it. My neighbor has to bring her unit in for repair as the first time we started it, the oil light was blinking to check oil, even though the oil level is fine. So the dealer will be able to see the rust first hand other than pictures. Based on the cost of the tank, I would prefer just replacing the tank if the rust problem gets worse - will be taking a wait and see approach before contacting Honda again.Honda's part site shows a new tank at $65 if you decide to replace it.

My takeaway there is that using fuel stabilizers with E10 is practically ineffective at controlling water intrusion, phase separation and the subsequent gelling and corrosion on fuel systems. Once you've poured in E10 gas, you'll need to either use it all up or drain it out before storage.Was somewhat disappointed that the additives Taryl tested proved useless but good I don't need to purchase more of that snake oil.
But adding stabilizers to E0 fuel, there's probably still something in like, Stabil to slow down the gas from going stale and really see it lasting the promised "up to 2 years". With E0, you're only worrying about preserving the gasoline and its combustibility. On its own, gasoline has built-in corrosion inhibitors so that should keep everything it coats from rusting.
Ive done the magnet test and it sticks to the tank, but I cannot see any rust on or in the tank after 3yrs of using E5/E10 fuel.. Heres some pics of the rim of the filler hole and the rim is not perfect but not in bad condition considering its outside 24/7. Also here's are pics of the fuel cap opener I made... Im quite impressed with my gen as its a fraction of the price of a honda and its holding up well so far,. Famous last words.. LOL
