Title: mpg 95 tdi auto
Post by: DCR on April 23, 2008, 22:36:50

 Has any one got any ideas how to up the mpg on my 95 tdi auto at the present prices I am getting about 70 miles for £20.00 about 18 litres do different air filters make a difference.I have tried to be gentle with accelerating but it doesnt make any difference. I do a varied amount of motorway and normal road driving.Maybe its just a real heavy motor .what sort of mpg is typical.
ALL the best. :lol: :lol:

that's even worse than mine!!

Since July of last year my recorded mpg has gone from 25 to a shade under 20 mpg. Mind you the air filter I took out last weekend might have something to do with that .. it was well manky  [-X

I did 600 miles on the motorway last weekend ,cost £90. I think thats over 30 mpg .   Â£60 @ 112p per litre , and £30 @ 115p litre.   can someone work it out ? !  That was the first time I've had a full tank ,and it feels heavy at the rear end !!
 Maybe if you only half fill the tank you would get more mpg?  :)  like F1 cars do , weight/fuel ratio etc. :)
 Thats with new air filter/oil change and some injector cleaner in the tank  .

RRR can get 30mpg outof her TDi, about 21 MPg with the 'van on, but that was a relaxed holiday in Wales.  27 MPG is a good average on a TDi.

Best improvement I've made was new injectors, clean the intercooler and pipes, turbo etc of all that s*** that gets in there.

£60 @ 112p per litre  =  53.57 litres.
£30 @ 115p per litre  =  26.08 litres.
53.57ltrs  + 26.08ltrs   =  79.65 litres.
79.65 litres...............  =  17.52gallons.
600miles / 17.52glns   =  34.25mpg.

that's pretty damn good mileage :clap: :clap: only wish mine was doing as well  :( :(

by the way regarding the original post, £20 @ say 110p per litre = 18.18litres = 4.0gallon, 70miles/4.0gallon = 17.5mpg :shock: :shock:

 Have you had the fuel pump timing checked as this dramatically effect how much fuel you are using, they have been known to move from time to time ?

 :shock:

Would this be picked up when the timing belt was done?

 It should be but depends who done it, I have known a garage or two that have done a cambelt and pump timing has been out.

 It can be adjusted without touching the belt though.

Thanks bejay :) That does seem too good ! but the fuel guage was reading just under 1/4 tank start and finish.  not forgetting plus the 0.9p 's  I forgot ! Is pretty bad on trips of only a couple of miles though :(
