Is diesel more economical any more?

Also petrol tend to be better and more economical on short urban runs compared to diesels which take longer to warm up so if your sticking to urban driving stick with petrol otherwise go with diesel.

Sorry you have it wrong petrol cars still have to richen the mixture on warm up (like the old choke but without the speed increase) Diesel cars require no such enrichment just a bit of heat from the glow plugs on a very cold day so they will always beat a petrol on short trips around town on fuel consumption.

Err, no. Diesels do not need to warm up. Petrols need to use a cold start valve and run on a rich mix until they've warmed up a bit. Petrol engines warm up quicker in order to turn off the cold start earlier.

Brand new diesel v brand new petrol, yes you'll save on the diesel (once you've saved the difference in purchase price).

Second hand diesel v second hand petrol, your into DPF (diesel particulate filter) and DMF (dual mass flywheel) failure territory and the diesel will start to cost a small fortune in repairs.

As has been said, the DPF shouldn't give any trouble if the car is used for regular 70 mile trips. Also, as far as I am aware, dual mass flywheels can be found on both petrol and diesel cars.

Given a budget of £1500 I doubt many cars new enough to have DPFs will be on the shortlist?

Personally I'd be looking at spending the money on a good condition old fashioned diesel, one from the 90s, rather than an average condition one from the 00s.

I still miss my old 94 Passat that cost me £700, yes it was slow and boring, sounded/drove like a tractor and a lot of the toys didn't work, but it still ran like a champ despite 250,000 miles on the clock.

If you can smell your fuel while sitting in the car you might want to get that checked out.;)

The very thought of having to use a diesel fuel pump to fill it is enough.

Vile stuff.;)

Exactly!!

I'm running a 196K 1.9D Berlingo van at the moment... Hits 55+mpg without fail worked out Fill to Fill....... Although its flat out at 75mph and noisy theres not a DPF or DMF in sight....

PSA HDI 90s tend not to have either... as do Xsara 110hdis...

Should get a decent Diesel for £1500 without DMFs and DPFs...
