For all those who don't understand the nanny state, can you tell me have you been filling your own and getting it to the same level when you do fill up? I never trust the attendant to actually top off.......

As always, thanks for all the feedback! In PA, we fill our own. Most of the time with gas, I fill to nozzle shuts off. Filled the diesel yesterday with the big truck nozzle. Took maybe 3 seconds to pump 16 gallons?

Truck nozzles aren't great for topping off, they shoot the fuel way too fast.

Winter mix diesel and summer air in my tires has me at 20mpg.

when I fill the 90, I continue topping off until I see fuel pooling in the filler neck.

I have recorded every tank of fuel I've ever put in the car and keep all that information along with maintenance and repair information in a google doc spreadsheet.

I usually get between 18 and 21 mpg based on indicated miles on the original speedometer.

I'm running a 300tdi/r380/1.4 transfer/3.54 diffs and 255/85/16 mud tires. 2" lift + roof rack, usually cruise around 70 on long trips.

Trevor - how accurate is your trip/odometer? Did you swap the speedo gears with the t-case swap? Mine gets mid to upper 20's. Same mileage before/after adjusting the pump and same mileage before/after lowering the diff gears.


Originally I was 235/85 with 1.2 case and 3.54 diffs now I'm 235/85 with 1.2 and 3.9 diffs.

Changed the gear, within 2 mph with a speedo app. Currently 265 75, 1.2, 3.54. These tires are temporary- bought a set of 7.50 xzl's due any day now. Rebuilding a spare 77 and will likely fit the 1.4 to the tcase then....just drove a 50 mile errand and noticed an ability to use 5th gear more......

LOL, when you're at the only fuel pump in a one horse town that's 40 miles of steep dirt roads from the nearest pavement, you get what you get.

This has been my experience with almost the same setup, if I lay off the throttle I do a little better at 65MPH but the 300TDI R380 likes to be at 55MPH ideally it would seem.

Also 5th gear really does feel like overdrive and unless I am almost at 60MPH I usually stay in 4th for throttle response

Just happened to check my 300tdi 90 the other day. First time I've bothered.
City driving, in a bit of a hurry. Lots of lights, hill starts, and long grades in third.
Thought it might be worse:
18 USG; 21 ImpG; 13 lt/100km.
Maybe now I will do a highway check.
265x75; VNT; 2.8 injectors; standard fueling; roof rack.
About to install a full width intercooler so may also compensate the fueling a bit.
Eric.

...pattern forming? I think I see a pattern, but will have to review thread to see for sure.

110 200tdi, lt77, lt230 1.4 and 235/85r16 all terrain. Getting 25mpg on kerosen and diesel. Winter gets it diwn to 20mpg (webasto preheater and cab heater). Once It had a 1.2 t-case and on a trip in Ontario It returns 30-32mpg but for where I live the 1.2 was too tall for the hills around..

My three door 110 has a 200, 1.2, LT77, 3.54, 235/85/16 KO2's, steel wheels, ARB, 9.5ti, light platform in rear. Best was 27mpg worst has been 23-ish. That was trip to Ouray.
Switching to 1.4 t-case as the "hills" around here leave the 1.2 wanting.
