Should I sell my diesel car to avoid any potential fall in value?

Apodemus

Coming back to the OP’s question...

For the costs of trading in a perfectly good car for another similar (but petrol) model, you could simply take it for a decent run down your nearest motorway a couple of times a month to keep the DPF happy. The extra fuel you use doing this will cost a lot less than you will lose on your trade-in and repurchase.

Have you been around a car doing a forced regen whilst parked? It stinks.

Where are the figures for whats coming out of the exhaust when its doing a regen? Not easy to find.

Well im sure it does stink, its like sitting on a furnace. but if it all came out the back then there would be no point in the dpf.

I don't understand why people keep posting this myth that diesels aren't for short trips.

Because modern diesels are fitted with a DPF filter that traps the soot and when it starts to get full then heats up to a high temperature turning the soot into harmless ash which it then ejects out of the exhaust. It can only perform that regeneration cycle on a long journey typically of 30 minutes or more and if it can't perform a regeneration cycle it eventually gets full and blocked up costing a lot of money to replace.

My diesel car is in its 20th year, on a mixture of 4 and 12 and 40 and 150 and 500 mile trips. Maintenance isn't a problem. It's had a few quid spent this year, but that includes a cambelt and big service, some suspension parts, ready for the next 100,000 miles.

Your 20 year old diesel doesn't have a DPF filter.

We don't know what car you have but I doubt if that is true, most modern petrol cars won't drop below 20mpg in anything except the most extreme circumstances, and certainly not on a regular basis (excepting perhaps super- and hypercars, but then it's unlikely your diesel is the equivalent of one of them).

Very similar for us with Mrs.G-J's current Mondeo 2ltr diesel over previous 2ltr Vectra...Mondy does double the mpg on the short runs she does, and I can get it up to 60mpg if I take it to work...as I posted on another thread on here:-

"Mrs. G-J does around 5000 miles a year, all short runs. The current Mondeo is way better than the 2ltr petrol Vectra we had before a really nice man wrote it off for us... vectra 19-20mpg, diesel Mondeo 43-ish mpg on the same driving (except the odd time I take t to work just to give it a longer run). We've had it almost 4 years now, 03-plate, 160-odd k on the clock, and been a great motor"

Depending on what you eat and the mileage and processes involved in getting it from source to your plate you may end up polluting more per mile cycled than his car.

Not sure how you think transporting a 13st person can take the same amount of energy as a 13st person and a 287st car.


A diesel engine will emit solids such as soot, I think all of jeepjunkies emissions will be gaseous.

In the next few years all diesel vehicles will be forbidden in Europe for using clean energy. Electric engined vehicles will be the future. Sell or not to sell / up to you

How are goods going to be transported?

The amount of energy expended as smugness.

And the food he eats that generates the energy he uses to cycle could have come from the other side of the world, will have been transported by truck from the point it entered the UK (import or grown out the ground) to the shelf with some foods such as veg being grown under powerful lighting in greenhouses. There is pollution involved in the production of the food he consumes and in disposing of the packaging waste/bodily waste (pee and poo) to provide the additional energy he needs to use to cycle.
