Arnold 6527238 Trufuel Trufuel 4-Cycle Fuel 32 Ounce (Case of 6)

Color me skeptical at first, but now I'm a believer. There is a performance difference between this and service station fuel with the added benefit of reducing wear and tear on my machines. Highly recommend. On a personal note, I gave my nephew a new gas can and $20, then asked him to put 2 gallons of high test in the can -- he looked at me like I was talking gibberish because the term high test was unfamiliar -- FWIW: premium is the modern descriptor. IDC what it's called, this product surpasses it. I only have one 2-cycle machine and I used the designated Trufuel in that, as well.
