I hear you, not sure how they do it up there. In my area we are at 4000ft and the blends are all different where we ship to and that is based on the specs that those cities require. There can be a different RVP spec as well as octane for each grade. In my city, the low octane is 86 and you can go 60 miles into New Mexico and their low grade is 87. Just sharing what I know about this market!Cant see it being a major difference, buy premium here at home, elevation of 2000', put it in my sled which is a much higher performance motor ( 170hp 2 stroke 800) and pack jerry cans full for the trip to the mountains over 500 miles away in a different privince, ride at 7-9000' while there, no issues. I know they have different fuel blends for seasons but ive never heard of different blends for elevation, worked at gas plants and refineries, also have oil and gas college education and we never once learned about elevation differences in blends of fuel. Only for different climates or season changes, essentially the same thing.
