Is it safe to buy a diesel now and make it last?

[cliffords]

We are retired and changing to two cars from having many in our family .
One good one and one medium one, but they need to last us a long time , buying now and not again for many years .

There are lots of diesels in our range and age preference , as an example a 2019 Tiguan 2.0 D Auto , but if we buy this we will keep it for typically 15 years all being well . Its Euro 6 now .

Should we buy diesels or is petrol going to last longer in terms of availability .

I searched threads this is not the petrol / diesel suitability debate we have that sorted , Its the will we be able to buy diesel in 2035 as an example and will the vehicle then only be give away or scrap due to the fuel situation?

Thanks

Do you think all the diesel powered vehicles are going to disappear tomorrow?

We've got 7 diesel powered vehicles/machines currently, and only 1 has an electric powered alternative now, all the vans, trucks, tractors,etc will still need diesel for many years.

a 2019 car in 2035 is going to be 16 years old, the oldest Tiguan's on sale are only worth £2-3000. You'll be fine, you just may have to pay to enter city centres, but who knows?

do you do enough miles and more importantly occasional long journeys for a diesel to work?

You will still be able to buy diesel in 2035, and I’m sure people will want them on the used market, even if it is towards the bottom end.

I’d still buy a diesel although I probably wouldn’t buy euro 6 with adblue, well not until manufacturers start making individual parts and not selling the complete tank. It makes for a very expensive repair, usually £2500-£3500, that buys a lot of petrol.

I wonder if the 5 cylinder D5 XC60 would be a good choice

Assuming the ban does go ahead (there is a slow push by various governments against it) then 2035 is 12 years away, and that is the date sales no new cars will be banned. Given the lifecycle of car development we will see IC cars being sold new close to that date, so it’s going to be 20+ years until IC cars a no longer commonplaces, and probably 30 until they are only in the hands of enthusiasts.

Given my recent experience, I'd avoid a modern diesel unless you're doing lots of miles. Even then there's lots to go wrong.

It's a shame as I'm still running an old 59 plate (non-DPF / ad blue) diesel which is great to drive, simple to maintain and pulls nicely. Probably not good for air quality though.

[Back2theFuji]

Sorry back to the original point, I wonder if diesel will get more expensive as demand drops (less demand so less produced) or cheaper (surplus from demand drop). Bet they tax it like mad and it goes up.

We have the car the OP mentioned. It doesn’t need long runs, they don’t passive regen at all, they just do an active regen every few hundred miles.

I don’t think I’d buy one now though - as Stevemcs mentioned, the AdBlue system (and things like triple pumped cooling circuits) terrify me.

I'd also avoid adblue on a car I wanted to keep myself for that long, after having some very expensive repairs as well, although luckily on an expensed company car. Warranty didn't cover it.

Agree with that - seems pointless even thinking about. I pretty well gave away a 17yr old C Class last year.

To the OP, if you do go ahead with this plan, I suggest getting the car under sealed. “Structure corroded” seems a common advisory and failure point on older cars - a few years ago not many would have made it to even that age.

You'll be fine with the diesel, assuming you do the miles to warrant it.

For info we have two 2.0 TDI tiguans, a MK1.5 and a MK2 both 4motion. Both owned form new and they have been perfectly reliable. The MK1.5 is coming up to moon mileage.

Fuel economy averages out to 40mpg for us, the same as our 530d estate.

No idea what the petrol tiguans get in terms of consumption but if it is above 30mpg then certainly worth taking a look rather than the diesels.

Our diesel auto 4Motion Tiguan does calculated 38MPG in semi-rural local use. Shows 42MPG on the display. Will nudge 50 (displayed) on a long run.

I did a 50 mile pretty steady round trip in a 1.5 petrol 2WD auto courtesy car and that showed 45 MPG. From comments on Tiguan forums it seems the 2 litre petrols are far worse on fuel, especially for local use.

Sitting typing this in our 10 year old Mk1 facelift (1.5?) 2.0 Tdi 4motion Tiguan. It will turn over 166000 miles on journey home today. It's been very reliable and would have another, although it's pre adblue Euro 5. Will continue to drive diesel as long as possible.

I would say it’s pretty obvious the price will go up. It’s profitable at the current margin due to volume sold after all.

It will be a while before there is an alternative to diesel for road haulage, therefore I would assume there will be demand for diesel for some time to come. If the price were to increase too much it would cause further inflationary pressure due to most goods needing to be transported.

I’ve kept cars from new for 10+ years but I try to keep them simple as possible as ime things start to go wrong. With the complex diesel engines will at 10 to 19 years old would it not likely produce some hefty bills?

[nickfrog]

Is there much benefit to diesel for an average mileage compared to petrol, even financially?

Modern petrol engines can be quite complex too and throw up hefty bills as they age.
