fuel
hello
I have a 99 cummins, 162,000 km
I have notice in the last 3 fuel fill ups, that I am using a little more fuel than usual. I am not blowing any white smoke or black. truck is running the same as it was before I noticed this..
anyone have any ideas ???
thanks

If you are in an area that changes to "winterized" diesel, it will do it every time.

How long have you had it?
It's getting colder, It runs richer until the engine warms up and that will kill your milage more than running the A/C. So if you are warming up a cold engine AND running the defroster which cycles the A/C compressor your milage will drop.
Also like Cougar said. Winterized diesel sacrifices energy density for cold pour properties. You don't get as many mpgs, but you don't get jello in your fuel filter.
