I am very pleased....I went from a 2005 f-350 diesel that had a BEST mpg of 16.5 to my Tundra. I just filled up today and the 3.65 gallon gas sure beats the 4.14 diesel! BTW my last tank I had 201.2 miles and put in 9.96 gallons. You do the math
Also the lie-o-meter on the dash read 18.1 mpg......don't trust the guages!!
