300tdi Performance / MPG
« on: December 07, 2009, 12:09:37 »
Hiya

Ive got a 1996 300tdi 90 with 83000 on the clock. It has got a standard size Allisport intercooler, Straight though exhaust, and an ITG filter.

I did exactly the same 150 mile journey on Sunday with another 1997 defender with standard intercooler, exhaust and filter.

We sat at 65mph pretty much the entire way - I used 3/4 tank of diesel, and the other one used 1/2, but the other one has better performance, quicker and a better top speed. Neither 90's smoke.

Im thinking that mine needs to be tinkered with by someone who actually knows what they are doing - Fuel pump has been tweaked by many previous owners by hte look it, but i can get it flat as anything, or drinking fuel

Do you know of anyone that would be able to undertake such a task?

any diesel specialist should do it. or a local performance car tuner/rolling road or try allisport?? or even a local land rover specialist.
there are plenty of places about also if funds will allow get a re-map that should improve performance and fuel consumption

Definately using too much fuel. I did about 200 or so miles this weekend ( about 150 on motorway/fast A roads and 50 on green lanes/minor roads) on 3/4 tank. I am using 2 stroke in the fuel which does seem to help MPG!

How much do you add and in what sort of ratio,  1/2 ltr of two stroke to 50ltr of diesel?

Just been out this morning and results are not good  :'(

Filled it up to one click on the pump, drove 30 miles, filled it up again at same pump.

30miles, 6.88 litres (1.5 gallon) = 20mpg

1 part 2 stroke to 200 parts diesel (about 1/4 litre per tank). See the post in the alternative fuels section.
