TD42t economy

[Alitis007]

I was much lighter when I bought it

Yep last time I put mine on the weigh bridge with an empty tray, 2 occupants and half a tank of diesel it came back at 2.7t

Could it be coz the steel tray is thicker and heavier than the back end of a wagon ??

Thanks again for everyone's input and i hope i get more replies so i can get a more accurate average of fuel consumption of these motors not only for myself but to others thinking of converting to a TD42

Yeah, mats has a steel checker plate floor with 5th wheel attachment and mine is hard wood, much heavier than sheet metal

I can carry 220L of diesel too.

Hi Alitis007,

I am a new member. I have a 1993 Patrol GQ II ST TB42E
I have been told as you increase the diameter of your tires your fuel economy gets worse.
What size tires do you think I should get.

What is the difference between a td42t's and a TB42E, is the td42t's a turbo diesel. Mine is a 4.2 injected petrol.

Increasing your tyre size only increases fuel consumption if you try to accelerate at a faster rate than normal, if your using your trip meter / odometer to calculate fuel consumption larger tyres will show a lower distance travelled because a 33"(285/75) tyre has a larger rolling distance than a 30.5" (265/70), so one revolution of the 33 will take you further than the 30 thus making it calculate to a higher fuel consumption coz of the lover odometer reading. Tyre size is totally up to you coz you need to work out what terrain you drive on and what you use your car for. The main difference between the tb42 and the td42 is like you said, one is petrol and the other is diesel.

The td42's are much much better than the tb42's too. Thats the biggest difference

Just did the Simpson crossing east to west my td42 got 19.5 lt per 100. The tb42 got 26 lt per 100 on petrol, for the rest of the trip I got between 16 and 17 lt per 100, dirt and bitumen, these cars both were fully loaded and roof racks. Unloaded city/ hwy I'm in the 13/14 lt range
