I haven't touched anything with a two stroke motor since I was a kid. Because I currently have a project where I'm planting over 100 trees in rocky ground, I decided to save my back, support the CCP, and buy a Harbor Freight power auger.
Upon reading the instructions, they were adamant about besides the 50:1 gas/oil mix that I also add fuel stabilizer OR THE WORLD WILL EXPLODE IN A BALL OF FLAME!!! Anyway, the seemed very serious about using the fuel stabilizer or voiding the warranty. Is that an ethanol thing or something? If I buy non-ethanol gas does that mean I don't need the stabil?
Though I know I overpaid because I was in a hurry, right now the fuel tank has the STP premix that HF sells for their two stroke stuff. 91 octane + oil + stabilizer. The manual didn't say anything about 91 vs 87 octane.
