Coleman fuel works in small engines, a lot more expensive that pump gas though.
If youve got to run it, try to run it out, or if it has a fuel cut off, turn that off so it will consume the rest in the float bowl/carb reservoir. The primary short term problem is the hydrophilic nature of the alcohol, it attracts water and when it gets enough that some will settle out it usually goes right to the pickup/low spot.

My casual byond-the-edge-of-left friend Slim Coleman is heir to the Coleman fortune. That fortune finances Slim’s unique brand of leftist action.
