Unbelievably, I attained 40.05 MPG on this last tank of winter blend gasoline! I didn't do anything different than I usually do...

Pump error? I dunno, I think I'm gonna get wicked mileage on my next tank, did 150 miles of highway and got double the number of miles I usually get on the first quarter tank. Makes me want to take it out for an all highway tank to baseline it. The other time I made this trip I got 45 mpg and the rest of the tank was city.

After some aerodynamic adjustments (taped off part of grill, removed passenger side mirror, turned in driver side (so i can flip it out if cops have issues)) and drove as granny like as possible and just last week attained best ever economy on my truck (24.5 mpg's). I also have decreased my Acetone additive to 2 ounces for that tank (average 15-17 gallons per fill) current tank has 3 ounces, as well as my normal additives of 10 ounces MMO and a tiny can of the Outlaw octane booster (required because of my chip, along with CA premium 91)

I know my weather here in SD is better than most of y'all but my best ever is my best ever

I want to do an all out highway run but it's really difficult. There is always someone who cuts you off or doesn't know where they are going.

I hope by spring to be in the high 40's.

I think this would be great fun to do. I may attempt it in the Summer. Atlanta has a perimeter highway [I-285] that is about 63 miles around. If I stay in the slow lane and drive the speed limit [55 mph], I may be able to get some great numbers.

My sweet spot is around 55mph. But on the freeway I always drive 65mph.
