Going by your trip meter, your average speed was 52.75 mph. 20 mpg is pretty respectable. It will only get better with time.

I'm jealous of your 36 gal tank. It really makes a difference, especially for towing.

 

So how many gal. did you refill with? you came pretty close to running empty. I try not to go that low on refills. did it take 35 gals? I find it takes alittle more than the computer says. My last fill up was 31.5 gals but the computer said 31
