WeX Posted June 21, 2012 Share Posted June 21, 2012 I recently changed from Petrol to Diesel too and I get around 50mpg from mine compared to less than half from my old petrol car. I drive 75% of the time on motorways and surprisingly when I once accidently slipped over the 70mph speed limit , I noticed my MPG went up. So with the proposed speed limit change to 80MPH on our motorways, I certainly think this would help peoples fuel consumption. Link to comment Share on other sites More sharing options...
Bonjon Posted June 21, 2012 Share Posted June 21, 2012 I usually get 52mpg on a 1.6hdi, and I have a rather heavy right foot. If I do motorway driving and stick to 70 I get 68-70mpg. Above 70 in mine and the MPG drops, most economical speed seems to be around 65. Link to comment Share on other sites More sharing options...
Riche Posted June 21, 2012 Share Posted June 21, 2012 Anyone who's into diesels and have been for some time like to offer advice on whether I might ever enjoy what I was expecting - perhaps when the engine 'loosens up'? - say 15k+? Any comments would be welcomed - Thanks Got a Fiat Fiorino 1.2 Diesel. I get 45 - 55 Mpg. I expected more but sheffield is a hilly place and very congested. My average speed in town is 15mph during working hours. I suspect the stop start of urban driving is worse that what the manufacturers consider urban driving.

It's not the manufacturers..it's the EU that have proscribed the test parameters that the engines must go through to get the consumption figures...

alchresearch Posted June 21, 2012 Share Posted June 21, 2012 I've never had any issue with supermarket fuel...without additive..although I probably get 1mpg extra if I use Shell or BP.. I guess it all depends on the car. Like Lab-rat says some cars with DPFs don't like it. But again, this could all depend on how the car has been driven and it's current mileage. I've seen cars with blocked DPFs at 40,000 which have only done local drives, and then cars with 100,000 motorway miles that have never had a problem or warning light.

My current car is 6 months old and I do around 40k miles a year,quite a bit of it on the motorway..maybe that helps.. Link to comment Share on other sites More sharing options...
danny128 Posted June 21, 2012 Share Posted June 21, 2012 Thanks everyone for your comments - it's been a pleasant surprise how many have been kind enough to offer advice in such a short time! It's certainly given me 'food for thought'. The motor is manual - 6 gears - cruise controllable - engine stops when stood - marks you for style of driving - talks to you - beautiful to drive but what I really was looking forward to enjoying (good mpg) - it's sadly lacking! The points made about cruise control, short journeys, servicing, hill work from cold etc are all probably relevant in my case but am particularly interested in the type of fuel I fill up with. I've noticed a slight difference now thinking about it in different brands but always thought if they're to set 'standards' of quality there shouldn't be much difference between them? Does anyone have any particular preference in different brands? Thanks once again to everyone:) Dont use cruise control on motorways as it will accelerate uphill and slow on down hill. on motorways you should accelerate downhill and increase speed just before you meet hill but dont try to increase speed during uphill as it is a waste of fuel Link to comment Share on other sites More sharing options...
old tup Posted June 21, 2012 Share Posted June 21, 2012 I run a 2001 mercedes E class 220 cdi around town 40-45 mpg,on the motorway 51-54 mpg.My car has done 84,000 miles I use supermarket fuel boosted every couple of months with Millers additive,it has an automatic gearbox plus cruise control.If you cruise instead of doing a Stirling Moss impression you will obtain maximum mpg,my motor is a large car and I,m more than happy with my fuel consumption and don,t forget to service yours regularly most important!.

ANGELFIRE1 Posted June 21, 2012 Share Posted June 21, 2012 Landrover Freelander diesel 2.2 SD auto 190 hp, close to 40mpg on a run, closer to 25mpg local. Nissan Qashqai diesel 1.4 105 hp 60 on a run, closer to 40+ local. One of the best motors we have had. Angel. Link to comment Share on other sites More sharing options...

My car had 89,000 when I bought it all motorway mileage. I drive on Sheff parkway & dual carriageway to work, so not exactly city driving but still DPF light came on with supermarket fuel. Stayed clear of it & (touches wood) never had a problem since. I think years ago petrol was petrol & oil was oil......but anyone who confuses this now-days is asking for trouble.
