Customer Question

My 2009 3500 6.7 seems to have suddenly lost a few MPG. Is there a reason for this? Also a brand new air filter plugged up on 700 mile round trip. The only thing different on this trip thru the mountains was fog.

Good morning and welcome to JustAnswer!!

My name is ***** ***** I have worked for a Chrysler-Dodge-Jeep dealership for 18 years and I will do my best to help.

What was the filter plugged with? Is the check engine light on? Usually when a customer drives on flat land then goes to the mountains the air is lighter and you may encounter a loss of MPG. The air filter shouldn't get plugged though and I tell my customers not to run a K&N because yes it flows more but in order for it to flow more then it's got to have bigger holes and dirt particles will pass thu, so I always recommend a factory micron filter to ensure the air get's filtered properly..
