I am assuming that your solely relying on the trucks computer to calculate your mileage? Try to do the hand calulation and you may find out that your about 1.2 - 1.8 mpg lower. Just saying that the computer is not accurate.
I was skeptical of mine at first too. Our Camry was consistently off by about 2 mpg. I've checked several tanks with this truck and it is generally within a couple of tenths, sometimes showing better, and sometimes worse than by hand calculation. I'll probably check again occasionally, but mostly I believe my truck anymore.
