e10 kills small engines. The stuff is terrible.
No it doesn't... Here is what happens...
- It has a tendency to absorb moisture more so than non-ethanol gas. This happens partly in the 1 gallon or 2.5 gallon can that people use to store their mower gas. This also means it gums things up faster over time then non-ethanol gas.
- In combination with the above, it tends to wreak havoc on the fuel delivery system of the small engine. In my case, a small B&S 3.5 mower fuel pump. That membrane is adversely affected by ethanol infused gas.
So... How do we deal with this?
- Treat your gas with a gas treatment formulated for ethanol fuels. It does help with what the fuel does to various gaskets and such, but at least you reduce part of the gumming issue.
- With the above, only buy enough gas for one month of mowing.... Not the whole freakin season's worth.
- Properly winterize your lawn equipment as you should be doing anyway.
- Perhaps Briggs and Stratton can sell some carb parts that aren't bothered by ethanol? Is that too freaking much to ask of them? Ethanol has only been around for eons now.
What I do?
I just buy my mower gas from a station that has a non-ethanol pump/supply. Haven't had carb issues in a few years now. With ethanol I was pulling the carb on my small mower once a year.
