Diesel or Petrol

Rite Chaps,

 

I am thinking or changing my wheels but have a bit of a conundrum, I only do very short trips and offended, I work only a mile away from where I live the local shops are less I do the odd fishing trip and the odd trip to the forest with the mountain bikes.

 

My problem is I could do with a van but have been told short trips will would not suit a Diesel and will end up with problems ? Has anyone had problems with diesels on short runs or am I over thinking it.

 

Thanks

Depends on the age of the van, as much as anything. Anything 3 years old or less will have a DPF, and that sort of short runs all the time will choke it within a few thousand miles.

Some vans and cars had DPFs from 2005 or so, it varies when they came in.

My inclination, with your day-to-day use, is to say petrol. It might be a pain in the aris, and you'll hate the fuel cost on your occasional long trips, but it'll be a lot less grief in the long run

Diesel, because once started the Diesel engine does not required extra fuel to burn in a cold engine, whereas a petrol requires more fuel until up to running temp. Your journey is short and therefore a petrol engine would be running on "choke", as it used to be, for the entire journey massively reducing mpg

 

The wife is in the same predicament working a mile away, I could not believe how much fuel a 1lt corsa would go through!

It will be an older car/van, not that fussed about MPG, its more will a diesel cope will such short trips . I have a 2.4 type s Honda so I only get 20 mpg anyway from what I am reading would a petrol van say a 1.4 might be the answer.

Regardless of age trip distance will not affect a diesel, diesels fitted with a dpf will need a run to clean out, but then so does a petrol cat!

 

An older diesel is unlikely to be fitted with a dpf

 

Petrols are hideous mpg wise for very short journeys

Some years ago I had a Pug 205 it was only an 1100cc and as with you my work was only about 2 miles away shops about the same I was amazed at how frugal it was to run it would be weeks before it needed filling up if it is only a small car type van that you are thinking about I would go for a petrol.

 

Having said that I changed my big 4x4 for a suzuki vitara 1.6 thinking that I would save on petrol bills only to find it was rubbish on petrol so I went back to a big one I do like my comfort.

 

There is one other option you could get a push bike to go to work on and for light shopping then with the money that you are saving buy a nice big 4x4 :good:

Could you explain why please?

 

It was mentioned on R4 not long back, there was some RAC/AA adviser bloke who said people who only are likely to do short journeys and low mileage would be better with a petrol.

 

I have no idea why, as, as far I'm concerned engines are witchcraft.

Iirc that is based on the price of NEW comparable cars, their usage of fuel (manufactures urban figures) service costs and resale value, with of course the derv car being considerably more to purchase, having higher resale value (why is that?), coming out on top by a couple hundred quid per year over 3 years if your doing 10k or more, any less millage and it might not be worth the initial higher outlay

 

We're talking a used small van that won't be getting anything like urban figures!

I believe the issue with diesels on short trips is to do with the turbo rather than the DPF. It will knacker the bearings & seals apparently. found this out after buying a low mileage diesel & having to call out the AA when it went 2 months later. Can't recall the exact reason but he said it always happens to low mileage diesels.

I can see where Paul 223 is coming from, and if you want a Transit sized van I doubt you can get anything but a diesel. If you want a smaller van I'd go with a petrol, purely based on service and repair costs, plus diesel is always a few pence a litre more.

Variable vanes tend to coke up and jam, nowt to do with seals or bearings, more to do with not enough right foot

Hi,

 

Stick with petrol if you only do low miles, modern diesels (2004 onwards) have Exhaust Gas Recirculation (EGR ) valves to reuse the exhaust gas and tends to carbon up pretty quickly if you only do short trips, the carbon build up eventually hits the turbo (if it has one) so the repairs get expensive, some of the newer cars also have the Diesel Particle Filters (DPF) as mentioned and those don't like short trips either.

 

If you do get one it's possible to bypass both the EGR and the DPF but it'll cost money (especially the DPF) so take that into consideration too.

 

Regards

 

Deker

Have a look at Honest John online (Telegraph), lots of threads and lots of comments. Problems for a modern diesel likely to be DPF and DMF depending on use. Some makes and models or year of manufacture better than others, repairs such as injectors can get very expensive on modern diesels. Check out specific issues on what you might consider, by model and year, e.g. early Volvo V70; injector problems (denied by Volvo but they changed the design), early years Subaru diesels; DPF problems (later moved nearer engine for increased temperatures and burn off), Nissan X Trail (2.2DCi); turbo problems (from engine being turned off before turbo cool down - still spins but no oil). Sometimes not every model is affected though. Modern petrol engines are much better than they used to be, but it depends on your budget. I don't know a great deal about van models or their problems if they have any.

I agree with most of the above. Modern diesels do give good mpg with low emissions but they don't like continual short journeys because the built in DPF maintenance cycle needs a monthly 20 miles or so run at motorway speed to regenerate itself. My local servicing shop charges £45 to regenerate a DPF and they do a nice trade from the local pensioners and young mums who've been conned by the fuel consumption stats into buying a modern diesel.

 

A mate has an 'X' reg diesel Astra van with 162K on the clock which I borrow occasionally. It only ever does really short local runs and not only gives no trouble but it's brilliant on fuel too.
