At the current price of $3.12/ gallon of 87 octane vs. $2.87/gallon for 93 octane and 5 gph vs 4 gph, the fuel cost per hour at 75% cruise power is 35% higher (over $4/hour) for about 8-9 mph extra speed. Not worth it in my book, especially since we spend most of our flying hours at 55-65% power, sight seeing.

Some 80 and others 100 hp. The 80 hp performs very well. I would consider the 100 hp if towing or putting floats on it. Bob Griffin upstate NY
