Tried running 93 octane. Over the last tank of gas I averaged 14.46mpg. That's odo mileage divided by gallons to fill up. That's almost a 2gallon MPG bump for right at 20 cents a gallon. I was getting 12-13mpg.
Doesn't make it worth it. Going to try out the 93oct while towing and see how it does.
Figuring the extra miles your driving with the better mpg it is going to be about a 2 dollar savings per tank. That is what I figured. I just filled up with 87 and will run a few tanks with it to see how it does and confirm the mpg increase with premium.

Cost per mile is almost 1/2 a cent more with 93 octane. cost per mile is a simple mile per gallon divided by cost.
Assuming a 32 gallon fill up you will go 80 miles further for an additional cost of around $6.50 for a tankful of premium. 80 miles is equal to 5.5 gallons of gas which costs ~$19 so you are ahead buying premium.

Really makes a difference. I'm not sure when I can get down to St. Louis but I suppose we can meet in between sometime at a campground and I'd even share that bottle with any and all who would like to partake.
Can't buy any ethanol free gas in St.Louis. It's actually illegal in St.Louis county.

I know a nice camp ground right in the middle of Iowa that we could all meet after Aug. 6 and share that bottle. I am going to try the higher octane in my 08 2500hd on the trip to Kansas in late July and see what happens. Heck I might even have an extra bottle and some ribs to throw on the smoker with some JD dipping sauce. Im getting 12-13 mpg now with ethanol Just solo. If what is being said is true,I might see 12-13 towing. Im not complaining, its a nice puller.

I owe you a bottle. I reversed my numbers in my post, damn dyslexia got me again.
I always use non-ethanol 87 octane. I took a 200 mile trip with the cruise control set at 65mph today. Once I got up to speed I reset the onboard computer and got 20.5 mpg. At 75mph I get about 17.5mpg. (2500hd/6.0/3.73/2011)
