Thread: 2.25 engine rpm

While I do not often drive my 2a on the highway, when I do, I routinely drive at 100kph, without issues. While I have an overdrive, I do not use it on the highway (too noisy), only using it as a gear splitter in offroad low range. I too have 7.50x16 tyres.

I too used to do 100 km/h runs daily when my IIA was a 2.25P and I used it as a daily driver.

Fuel consumption was 17-18 l/100.

Only a bit.

FWIW, I did the nullarbor in a 2.25 D on 90-100 without an OD (but with ear plugs). Averaged about 9.5 L/100.

Bit hard to say. Most of the time it is used offroad on the property or across neighbour's places to the village, and when on the road it is a long way to anywhere, so I must admit I have not really tried driving moderately on road far enough to measure the consumption. Both on long trips and offroad consumption remains around 18l/100km.

John

i hadn't thought about fuel consumption, but i was trained early, my first car was a 49 vanguard, 18 mpg, so anything better than that is great.
you gotta burn it to go, so lets go.

thanks for your comments,
just had a good weekend drive around, absolutely no idea of consumption or mileage as the speedo reads in mph about half of the gps kph readout,
but about half a days drive means add 35 litres, which is meaningless...

not quite, it means you had about 5 usable ones left...

which I could have used to take me 20 odd miles from the nearest petrol supply...

but like all sensible series owners, I carry spare fuel in a jerry can.

and have an overhauled second tank in the garage to fit one day.

They do about the same as a V8 Disco, a 49 Vanguard,with the rear wheel spats and the one with the right hand column gear change,dad had one,and if you rushed 1st to 2nd it would jam,and my job was to lift the bonnet and unlock the levers,it was traded for a 54 Spacemaster sedan.

cheers

With a right hand column change, you wouldn't have been able to signal a right turn and change gear at the same time, would you?

I have a vague recollection of some other vehicle I travelled in as a passenger have a similar problem of the gear change mechanisms getting confused. I think something used to go over centre when the parts were a bit worn. It might have been a side valve Hillman.

I remember a similar problem with my b-i-l's 49 Ford Custom.
