Are you determining the MPG by the trip computer or the actual miles traveled with a full tank?DainBramaged wrote:I have always monitored my gas mileage and highway mpg has always been ~21. Over the past year, it has slowly and steadily gotten worse and now I get about 15.5 at 70 mph. I get bad in the city also. Around 12.5. Any idea why?
The only thing I've done aside from routine maintenance is replace the radiator fan clutch. And I replaced it out of the annoyance at the noise level and the (irrational?) fear that the additional drag would somehow affect MPG.volvite wrote:Any changes to the truck? New tires? Have you changed the air filter? Driving style?
At first, only by the MPG trip computer, but then I did actual miles just to double check it, out of paranoia...lol.twinblown wrote:Are you determining the MPG by the trip computer or the actual miles traveled with a full tank?
