Ethanol strips oil in 2-stroke engines, I have been told. So they tend to run dry and get a lot of wear. But are most 4-stroke these days? |
They are, but come the end of the season you can be left with fuel sitting in the tank and lines for 4 months. Also it’s unlikely petrol mower manufacturers have been as diligent as car manufacturers at ensuring their various hoses and seals aren’t attacked by the ethanol.
Plus, if you use a petrol mower chances are you have other petrol tools, and these invariably use 2-stroke engines. So unless you want to keep two cans sitting around you might as well put premium in everything.
