S Type Diesel Fuel Consumption
Discussion
I have not posted on here before, I am more used to the Lotus Elise page.
However, my 2005 S Type Sport Diesel Auto has now covered 22000 miles, and its average MPG for the last 8000 is only 28.1 mpg. Even on long motorway runs I struggle to exceed 30 mpg. My dealer can find nothing wrong! I wonder what other users are finding with their cars, since my wifes petrol BMW is proving far more economical!!
Any comments will be appreciated!!

I have had my S Type Diesel Sport now for 2 1/2 years .Great CarFuel consumption has averaged 32.3 over 72000 miles including my daily commute to London and sitting in traffic that goes with it. If I spend all day in traffic consumption drops alarmingly but on good run 35-36 achievable.Driving style and conditions seem to affect consumption a lot .Even so 30 + from quick luxury car is not bad
Yes, I have 3 friends getting around 32 mpg average. Even allowing for quite a lot of local driving, I remain disappointed with my consumption. In the past I have generally equalled or bettered road test results for the cars I have run, but this time I can get nowhere near. Back to the dealer (yet again) I think!!
Doesn't sound too bad to me. In stop start traffic the twin turbo's eat the old juice.
My father-in-law, over 60 and NOT a fast driver, has averaged 26mpg since new almost 3 years ago. He can get nearly 40mpg on a long cruise though so that illustrates the huge difference of the driving conditions.

The economy on mine is mid 30's. To clarify most of my journeys are quite long, around town the diesel can be very poor because the CR engine takes forever to warm up! Eg driven gently on a cold morning, even with no idling it can take 15 miles for the temp gauge to hit its normal position. Some warm air takes around 8-10 miles. I have found that on a run say on the A1M, if I fil up & reset the trip, it'll show 42-43MPG, it's deffo low speed short journies that kill the MPG.
I've heard of Petrol owners getting low 30's on a run, especially later models.

Interesting. I had the thermostat replaced soon after I got the car and it cured the slow warm up for about 6 months. It has now reverted to taking 10 to 12 miles to get up to full temperature. I have had all the gearbox reprogramming done along with the new transmission fluid, and again, this improved things for a few months, but the consumption has deteriorated again, accompanied by the gearbox groans on kickdown and the reluctance to move into 6th gear until it is really hot. Definitely back to the dealer!
Thanks.
Thanks.
Crikey....that's not good news, I was expecting a little better than this!
A Jag S-Type diesel was top of my list of a replacement for my Saab 9-5 Aero auto in a year or so's time, on future economy reasons as well as I just like them, but, the Aero averages 25-27mpg on my within the M25 daily commute's and I easily get low-mid 30's on a run and that's giving it some stick as well........
Might have to think about whether to keep the Saab for a lot longer now and just mod it....300hp/400+Nm and 30+mpg....so do I need a diesel....

I think it is almost entirely dependant on motorway mileage linked to average speed! My previous diesel achieved consumption better than the various road tests, whilst the Jag is about 4 mpg down on average. Some owners claim very good consumption but probably spend most of their time on long distance motorway cruises.
I bought a 56 plate S type Diesel Auto with 10K on the clock for business use a couple of weeks before Christmas. My previos business wagon was an Audi A6 Avant 1.9 TDI manual which averaged 45.3 MPG over the last 35,000 miles of ownership so that is one of my benchmarks. My second benchmark is a colleague with an O4 plate S type diesel manual that he has owned since new.
I live in Warwickshire and the first two weeks of ownership included runs to Pymouth, Scotland and Hampshire including my 70 mile round trip daily commute to work. Over the first two weeks and with realtively conseravtive driving it averaged 41.5 mpg. My wife then had the car for 1 week of local driving and the average MPG immediately dropped to 36.5. I then reset the trip and have used it for normal business and commuting use for the last two and a half weeks. for the first of these weeks with conseravtive driving I squeezed just over 39 mpg. Last week I gave more normal wellie and the average consumption has just dropped below 37 mpg and is still falling. This means that for the last week and a half the consumption has been below 37 mpg. (My round trip commute is about 46 miles motorway and 24 miles suburban A roads).
My colleague with the manual version (done 45k miles)drives his quite hard and so far his avarage consumption certainly appears to be better than mine to the tune of about 3 to 4 mpg. He suggested he could get low 42/43 on a long run and about 36/37 on his daily commute (about 40 mies round trip but mainly out of town dual carriageway).
Clearly my colleague and I both live out of town and have longish motorway/dual carriageway commutes so our consumption figures are going to be to be better than average.
Hope this helps

Thanks, useful information. My previous car was a Passat TDi 130 Sport manual. I rarely dropped below 40 mpg and my motorway best was 57 mpg. When I first bought the S Type I saw 42 mpg on a steady motorway trip and generally 30 mpg overall, which I found acceptable. The car is booked into the garage yet again for 2 days to hopefully sort out the mpg, gearbox, air con, heated front screen, seat memory and radio interference! Then I will think about buying the exhorbitant extended warranty - £850 for one year, £1750 for 2 years, before the worst happens!!!!!

Mrs Hex's MB warrantee is up for renewal and they want over a grand for one year.gregp said:
BMW wanted £440 for 12 months extended warranty on my wife's Z4. I never paid more than £500 when I ran a BMW 540! The costs are ultimately a reflection of the expected cost of warranty claims. Say no more!
Last year MB felt her car had caused so many problems that they paid the bill for us. Still I guess the year before they'd had the car almost as often as we had
