Just bought a Craftsman 21” push mower with a MTD 159cc motor. I won’t be using it until spring. My previous mower, with about 20 years of use, was rusted out, had wobbly wheels, and always seemed to make slanted cuts, no matter how I adjusted the height. I was planning to buy a new one next spring, but, while wandering around Sears (which is closing in Canada) I noticed their last mower at half price and I bought it.
The salesperson advised me to use 92 octane gas because “the carburetor in the new motors is smaller and they clog easier.” The manual recommends 87 octane gas with up to 10% ethanol. This prompted a search on the web and I came across this site, LawnWorld.
It seems that the real issue about gas is the ethanol content, which is common in 87 octane gas, but might not be in 91 octane. So I did a search and found gas stations in my area which sell non-ethanol gas. Any suggestions about which gas to use?
