I will never use Stihl Ultra. Adding a second year to the warranty isn’t worth running that crap. I’ll stick with the same 40:1 mix I always use with either Amsoil Saber, Echo Red Armor, or Husqvarna XP+ always in 90 octane ethanol free gas.I know of a guy that purchased a 261 Mtronic and bought their oil to extend the warranty. The piston/cylinder were toast in 9 months. Used the correct oil and ethanol free premium. It passed the pressure/vacuum tests. No clue how it failed. He had to pay the labor costs. Only the piston and cylinder were under warranty.
