Poor Fuel Economy

[2.slowjetta]

I have a 94 Jetta TD and I'm fairly new to the diesel world so i'm not sure where to start looking for problems.
my car is only getting about 550 kms per 50 ltrs. The car seems to run fairly well and has a half decent about of power IMO, it never had a problem starting all winter and was never plugged in.
let me know some things to check out, I don't have any access to an IP pump timing dial guage(is there anyone in the Kingston Ontario area that could check the IP timing for me?)

Ideas?

Brakes dragging? Poor injector spray pattern, timing like you said, bad wheel bearings? Clogged exhaust or intake? Poor compression maybe on one cylinder since it starts ok.

check your tire presure , if the roads are in decent shape ( meaning no snow / ice )  , fill your tires 1 or 2 pounds below the max rated presure on the sidewall .

your economy will go up .

check the front end of your car , worn suspension parts , balljoints / tierod ends , will kill your economy .

75 wieght synthetic oil in my tranny also seemed to help .

also try to run the engine at as low of a rpm as possible when cruising .  for my car 2000 rpm seems to be the magic number from incredible economy to ,  average .

also going from a stock exhaust to a 2.5 inch exhuast make a huge postive difference  .

Check your boost, my '98 1.9l wastegate is seized open so it is dumping most of the boost. economy went fron 950km to about 700km from one week to the next.
