I bought a new 2013 Tacoma 2.7L PreRunner, 4-door, automatic, because my research indicated these trucks averaged about 22mpg in the real world. I have about 3000 miles on it now and it averages about 17mpg, and has never gone over 17.8, even on the highway. The dealer is telling me it needs to have a relatively long break-in period (at least 15k miles) before I will see the real gas mileage improve. He said they will do a consumption test on it when I bring it in for the 5k mile checkup.
If what the dealer said is true then great, but I'm afraid I may have a lemon here and I need some ammunition. Could you guys give me some feedback on what your newer model 4-cylinder Tacomas are getting on gas mileage, particularly when they were new?
