My Eco's MPG just too a serious hit. I usually get upward of 25MPG but just this week its dropped to an abysmal 12.5MPG. That's half!!!! The only thing that happened was the weather got cold all of a sudden with a recent snow storm, I am now using remote start to warm up the truck for 10 minutes every morning, and the crappy 87 fuel that I put in has now been switched over to the winter blend.

I have no idea what is going on. Please help!











(Hopefully this thread takes care of this nonsense for this season, but I doubt it. Also, hopefully people realize I over embellished a bit.)

I'd recommend you manually calculate your MPG and ignore the computer's calculation, because as noted on other threads your remote starting messes those up.

I'd recommend you also do a reset of the MPG calculation tonight when you park for the evening. And write down the gallons used. Tomorrow, after you get in, see what your average is as well as gallons used. Then do another reset and do your normal drive. When you're done, see how many gallons used, miles driven AND what the truck says. Now pull out your calculator and do the math.

I think you'll discover that the warming up is killing mpg, that winter gas and cold weather are having an impact, but that in reality you've dropped maybe 10% as compared to pre-winter.

If not, then you've got something mechanical going on.

In addition to Ricktwuhk comments, consider the following .....

• more rolling resistance (especially at 1st take-off).
  • tires less flexible.
  • differential lub'.
  • transmission fluid.
    etc..
• consider (re)checking your tires' pressure.
• any seasonal ballast?
• the engine warm-up mode is longer. *fuel enrichment.
  etc., etc., etc..

And last, but not least ... Winter - It happens every year.

for every 10 degrees of temp you lose a pound of tire pressure. Check your tires. Colder aircharge temps will also have your ECU adjusting in more fuel. Warming your truck for 10 minutes (wow...thats a long time) is probably burning 1/2 a gallon just sitting there, as on a cold motor the ECU is going to dump more fuel in until the coolant warms up. Try warming the truck for a minute or two...any longer is simply wasting gas...your oil is already up to enough temp after a few minutes unless you're in Antarctica.

I'd blame the remote start, do the math yourself. You can subtract the fuel burned during your warm up from the fuel used during driving and come to a better number.

Well, it is obviously 10 minutes of run time with zero miles to show for it . .

Try going without the remote starter for a tank or two and see what your results are . . .

I think the OP was just being sarcastic anyway. I also think he's a LEGO.

I don't care how low my mpg gets I will remote start mine every time I leave if it's cold out. You also won't see any threads started about my bad gas mileage either. I traded a lifted crewcab long box 5.4 in that was getting 10 mpg so I'm happy as can be with my 15 mpg and remote starts. It's all about choices.

Yep I just edited my post after I realized what happened
