I can’t thank Brad enough for recommending the Opti Mizer MAX fuel stabilizer. I bought a Cub Cadet XT1 and I thought in ran well the first season I had it. When I took it out for the next one it ran so poorly I was ready to take it back. Brad said to try Opti Mizer Max and about half way through the fuel tank I swear it was running with more power and smoother. I could actually throttle back a bit and cut the same at a lower power setting. I can’t wait to change the oil next and use the Opti engine oil product next. Thanks for a great product.
