2000 ram 1500 using a lot of gas
 

my ram 1500 5.2 liter seems to be using a lot of gas. the motor has about 78000 miles on it. Seems to be running fine not missing or any problems. Just wanted to see if anyone had any ideas. Thanks

You could start with a compression test along checking the spark plug burn deposits.

And check the plenum. :)

Define "a lot of gas". History?

I don't know why anyone complains about gas, my truck gets at least 45mpg and gets from 0-60 in about 1 second.

All you can do is clean injectors, run seafoam, keep it well tuned with stock ignition parts, keep proper air pressure, and don't drive it like a racer.

If it's truly using too much gas, like below 9 mpg in daily driving, then you should have fouling plugs and smell gas in the exhaust plus other symptoms.

The PCM is very good at monitoring that everything is working properly to the point that it often is overly sensitive about generating fault codes. If the excessive fuel consumption is not your imagination you most likely have a problem with either the transmission or something else in the drivetrain that is making the engine work harder. Do you let anyone else drive the truck like maybe teenage kids? Someone stealing gas at night? If you drop it into neutral does the truck slow down more than it should -- faulty brakes dragging? Are your brake discs or drums excessively hot? Try to consider everything that would make your engine work harder. Maybe try a different gas station -- crappy gasoline --- to much ethanol? I got a tank of gas a few months ago that really messed up my truck but it generated codes.

no one else drives the truck but me or the wife. doesn't seem to have transmission issues. i do burn the cheaper gas. never has gotten more than about 12 or 13 mpg. thanks

i will check. thanks

i will check that. i had heard of that before. thanks

12 or 13 mpg. just thought it should get better. thanks
