Equipment that sat through the off-season on last year's fuel — it doesn't start cleanly in the spring, runs rough, and the carburetor is gummed up. Two-stroke mix is for two-cycle engines, but a lot of your equipment runs four-cycle engines that need straight fuel at the right octane. 110-ounce (approximately 3.4-quart) container of ethanol-free 4-cycle fuel. Ethanol-free formulation prevents phase separation and moisture absorption that happens with ethanol-blended fuels sitting in equipment over the off-season. No mixing required — pour directly into the 4-cycle engine fuel tank. Compatible with all 4-cycle small engines: lawn mowers, tillers, generators, and other outdoor power equipment. Standard in the service trucks of outdoor power equipment operators and small engine mechanics acr Stocked at Crofton Lumber and Akron Lumber.
