Comment How about small engines? (Score 1) 432
I have a number of small engines ( 2 and 4 cycle). The local small-engine shop will cancel the warranty if you use anything but 100% gas. My Husqvarna chainsaw states, in the manual and in bold letters, to ONLY use 100% gas in the 2-cycle mix. It's out of warranty and for a while I tried e10. Ended up replacing all the lines and rebuilding the carburetor last summer.
Luckily, there a several stations here that still still it.
