Does high test gasoline contain ethanol?
Our small engine repair serviceman suggested to use only high test gasoline in mower engines as it is not blended with ethanol. Is his information trustworthy?
The 10% ethanol in pump gas won’t make any difference.
I’ve been running my mower on E85 for 2 years without any problems. It’s a myth that ethanol will hurt an engine, as long as it isn’t allowed to run too lean.
