Alright...I've gone through four tankfuls so far. I've got a high of 25.86mpg and a low of 25.07mpg. My overall average so far is 25.43mpg.
These are the particulars...
75% city, 25% hwy, (I'm on summer vacation, so my driving is basically beer runs to the store).
PSI kept at 36lbs.
No weight in back if not needed
Driving like a freakin' grandma
So far I'm very pleased. I'll be taking the Taco on a road trip to Houston next month to catch a few Cubs games with my son, so I'll be able to get a good solid highway reading then.
