260 GT Sunoco (100 Octane)

shadows · 06-01-2022, 05:50 PM

Has anyone used this Sunoco 260 GT Unleaded Gas? I had to look it up online to see what the Octane rating was as it was not listed on the pump.

I live at altitude and our standard offerings are 85, 87, and 91 Octane. My m35i manual says it is best with 93, minimum 91. Would 100 be damaging to the engine? or not even worth it at altitude 6,000+ ft Denver Area.

No, a higher octane won't damage your engine.

Thanks! Might try a 1/4 tank 100 and 3/4 91 as a start and see how the engine behaves. slowly increase to some type of 30/70 ratio to achieve 93 octane.
