I DD my '97 D1 with 300Tdi. I've been riding my bike more and more, however.
I had a '93 RRC LWB I sold to Craig Spaeth. It got around 25 in town. My D1 started out pretty decent at about 22, but I'm down to around 18mpg.
Kinda disappointing for a Tdi. However, some of the guys I've talked to who have owned Tdi's say some just seem to run better and get better mileage than others. Oh well.
tune your pump. I'm getting better power and using less pedal and getting better mileage with the pump richer.
right 04 DII on 255/85s. soon to have a refreshed engine and....parked. will be on the bike all summer as much as possible. try to keep driving down to just weekends.
Timing is critical on a Tdi, more so than the fuelling settings on the pump itself. A 3/8" (9.5mm) drill bit works well as a timing pump locking tool, and you can then visually inspect the flywheel locking slot through the tapping in the bottom of the flywheel casing.Tried turning it up a bit, but the EGT's went pretty high very fast. I was at 1250 very quickly. I turned it back down a little. Now it runs great, good power, but mileage still sucks. I'm sure it needs tuned properly.
I have had a Land Rover in some form as a daily driver since 1991. The current one is a 1969 Ser IIA 300 tdi hybrid I built from parts. 9 years and 110K on this one and still going strong. :safari-rig:
