Of Mice & Men

G'day all,

Just back from a great holiday in Surfers Paradise & then Fraser. I own a 92 model diesel Landcruiser, & my vehicle does not have a tacho. I am hoping that somebody with similar vehicle, that has a tacho, is able to tell me at what speed I would be travelling at in 5th gear, when the revs are starting to go into the red zone, or perhaps the orange zone if there is one, & what speed do you guys sit on for those long free-way trips.

Thanks in advance,
OM&M

The governor will come in between 160-170 kph.

At 2500rpm I would be going at 100kph.
It works out to be for every 1000rpm the vehicle will do 40 kph. this should give you some idea of revs you will be doing at any speed in 5th gear.
Anything over 100kph and the fuel gauge will drop like a brick, so at 100kph and 2500rpm the vehicle is not working hard at all.

Same here. I have a turbo diesel and I sit on a 100 kph @ 2500 rpm. I get approx 14L per 100 km.

Hi OM&M

I've had my vehicle up to 140 km/h at which it was doing 3500 rpm, but it drank fuel like a Boeing 747. Most of my driving on decent roads is at 100 km/h partly to conserve fuel and partly because it's too expensive to go faster in most of the country :)

I doubt you will get in anywhere near yellow line in 5th, as said, Governor will stop you overrevving, but it wont if you shift back to 4th or 3rd. This is where you can damage a diesel. Rule of thumb is dont do it at any speed over what the motor can pull you at in that gear flatout.

Thanks for all the help guys,

What you are all saying makes sense, on the way up, towig the fully loaded camper, I was sitting on about 95k's. On the way back with no food & water on board I was sitting on the speed limit, i.e 100 to 110k's. on the way back the cruiser was getting about 100k's less between refills.

Thanks again, OM&M.
