2 stroke vs 4 stroke Ethanol ?

XMAN · Post by **XMAN** » Fri Apr 20, 2012 9:37 am

..Saw a video on ethanol in gas yesterday..not good as we all know..is a 4 stroke less apt to have problems than a 2 stroke...the mechanics in the video said that ethanol in gas is 80% of the problem when people bring in their motors..guys are having to change their gas filters 4-5 times a year..carbs are being ate up also..and now i hear we may be going to a 12% mix...if so i'm going back to my tube..a new big-man will only cost me a 100 bucks a year....X

I converted both of my small 4-strokes to propane

2 and 4 stroke are equally affected.

Kevin,
I understood that the newer motors were okay with 10% ethanol, but are they okay with the 15%?

I put Sta-bil in my gas tank to help with the ethanol and keep my injectors clean. Truthfully, I don't REALLY know if it helps or not.

Mark, anything above 10% will definitely cause issues.

not just the motors, better change your fuel lines to the gray/blue fuel lines made to be more ethoanol resistant before breaking down and screwing up motor filters.

Mercury has addressed this issue many years ago . Anyone can call mercury and ask for the consumer affairs department. From there you can ask the question about alcohol or ethanol.
