Horrible Mileage.....Please Help

[jtanguay]

I got new nozzles but not injectors.. is that good enough?

if you set the breaking pressure, yes.  and if you don't, at least you won't have to worry about burning a hole through your piston(s)  :lol:

I also forgot that when I replaced my injectors things got tremendously better in the MPG department. If it has been 50-100 thousand miles you might try that too if the diesel, oil, and filters change doesn't help. Injectors do wear out over time and I think that the bentley says replace them in the range above.

running a lubricity additive and using a 1 micron filter will greatly increase the nozzle life  :wink:

lubricity additive (WVO, VO, ATF,)
anything thicker then diesel (oil) should be fine due to the season changing but don't add to much. just to drown out the (Winter fuel)Kerosene. it will change the internal pressure of the IP... keep it clean

winter fuel gives horrible mileage around here.
