Do you use a fuel additive, which one?

The biggest problem that I find with E10 is that when it goes bad, it forms a very hard crust in your fuel system. The "old" gas used to form a softer "varnish" type of residue that was pretty easy to dissolve with carb cleaners. The newer hard crust from E10 is much more difficult to remove.
I thnk the only additive that is necessary is Stabil, or other fuel stabilizer, IF you are going to store the vehicle for more than two months. Remember, running the vehicle while it is in storage DOES NOTHING to prevent the fuel from degrading.

Stabil for gasoline that might sit awhile and Howe's Lubricator for the coach while its sitting.

what is Marine gas? AFAIK, all of the marinas just pump out the standard gasoline at an increased price.

Around the river in the Portland OR area many marinas sell non-ethanol gas. I just call it Marine gas.

I use Sea Foam in the diesel including the gennie

My Carb wizard said to use Marvel Mystery Oil. So far no problems for us.

There is a reason that planes DO NOT use anything but PURE GAS. I have been using avgas/2 stroke oil in all my lawn equipment and avgas in my lawn mower. I haven't had any problems in two years. I also use it in my Honda E2000i and it works great.

Am I missing something?

The reason I found this thread was due to a search about what kind of gas to put in my toy hauler gas tank. It will most likely sit for a very long time as I only use the trailer during the summers. I was thinking about avgas or marine gas (non ethanol).

Am I being to particular?

gas treatment post

2007 Safari Simba with a Onan 5500 generator.

Well before 2007, practically all small gas engines (carbs, jets, fuel lines, seals and gaskets) were built to run on E10 gas.

We've been running E10 since the mid-90's, exclusively. The issues in the mid-90's when E10 came out was engines running too lean (burning holes in pistons and overheating valves), not much more. The rest was hearsay and tails.

So while I'm against the grain here, I'm 100%, yes 100% sure E10 gas is not to blame. As with any rubber hose, from any time in history, they fail. It could be an age issue, temp, environment, or simply old gas that ate that fuel line. It happens!

E10 is here to stay, and if you don't like E10, well brace yourself for E15 and fewer stations who carry straight gas. Its only a matter of time.

Don't kid yourself about the damage ethanol can do to small engines. I have over 20 pieces of equipment including, lawnmowers, weed eaters, leaf blowers, chainsaws, rototillers and snowblowers. Most of them are less than 5 years old. I was replacing gas line every six months on multiple pieces of equipment because it either swelled and started leaking, or got brittle and broke into pieces. None of the lines on any piece of equipment lasted more than a year. It got so bad I was buying gas line by the 50 foot spool.

About 2 years ago I switched from regular gas with 10% ethanol to premium non-ethanol gasoline. I'm sure there's no benefit to using the premium grade, but it's the only thing I can buy in our area without ethanol. Since I switched I haven't had to replace a single fuel line.

After having problems with my Onan gen and a small tiller I started using Soltron. Solron is an enzym based additive. Both the Onan mech and the small engine mech advised I use an enzym based additive.

Shade tree mechanics like to blame it for stuff, but anyone with a history with gas engines remembers lots of fuel problems with old gas even when there was no ethanol involved.
