ive read in places that people are getting low 40s to 60s from a tank on these diesels... im only getting 36mpg to a tank. ive cleaned the egr and inlet , service and drive it gently.. what else could be wrong and worth checking ? I always fill it up with shell diesel aswell

Hi Adam,

 

I have the 2.7 Diesel in my S Type and get about 30 mpg round the city and up to 53 mpg [once] must mostly about 45 mpg on longish drive with mixed road conditions,

 

I was a getting about 5 mpg less till I had a Terraclean service, which cost me £120.  Just check it out on their website.  It cleans out your fuel system and I thought it well worth the money.

 

Regards,

 

Peter.

forgot to add .. it had new injectors and a fuel pump 6 months before I got the car.. along with a fuel system clean

could this be a symptom of injectors not being coded ?

Injecters will need coding to the car/ecu and thats most likely why you get poor mpg.

You will need specialist equipment for the injecter coding.

I have emailed the company who carried out the work to see if they were coded

Ok
