Long term ownership preventative maintenance - Dinitrol + ?

My March 2016 Landmark has now done 41k miles.

I am coming to the conclusion that I will be keeping it much longer than I anticipated as there isn't a realistic replacement on the horizon.

I would like a BE or decent hybrid Defender, but JLR don't seem to be going that way. The Rivian R1S is still looking attractive, but as discussed elsewhere is rather large to get through agricultural gateways & into UK car park spaces.

My Landmark has been pampered in terms of servicing, oil & filter change every 6k miles etc...but it's 4 year old now, and I think I'll be keeping it for at least another 4 + years. With that in mind what steps should I take to preserve it?

It's used gently off-road when I'm shooting, and I live off a by-way, so there's lots of mud about. I wash off the underside whenever there's salt on the road, or excessive mud build up. I don't wash the exterior very often, but the bodywork is 100%.

Is it worth treating with Dinitrol. In which case any ideas of cost & recommendations of someone to do it in South Hampshire would be appreciated.

Bodsy will flush the gearbox next time he's this way.

I have a WD warranty which runs until March 2021 when I expect to extend it for another 3 or 4 years.

What else should one consider?

If its going to be a real keeper take a look at the top end treatments from Buzzweld.
The basic treatment is equivalent to dinitrol really but clear which in my view is better as you can see if there are still issues underneath.

Thanks

Thanks Andy.

Buzzweld certainly looks impressive. No detail for D4, but assuming prices similar to D3 the full Platinum treatment would cost £3,500.

Basic is a more reasonable £500. They say:-

Have you had either done to a Disco Andy?

Maybe there’s someone on here who has?

I've self applied their UP stuff to our sport and it seems to be holding up reasonably well and it had next to naff all prep before i put it on.

The D3 I'm going to go a bit deeper and prime, paint and cavity it on the drive.

I had my D2 done with Dinitrol by someone and to be honest I could have done it better myself so will do with the D3. The Dinitrol has worked to be fair but really could have been a lot better.
I think the thing is for a £500 treatment there isn't much else they can do other than steam clean mask and spray and what you really need is either that every couple of years or a decent abrasive run after the steam clean to get the loose off and to remove every single under try and water trap under the car. I removed a lot on the D 2 before the dinitrol but in hindsight the arch liners should have all been out. The tank should have been dropped etc etc. Thats where the extra money is coming in for Buzzweld. I know the first RRS they did they actually lifted the body to do it but that may have decided thats just not reasonable to do now

If you are only keeping it 8 years, I wouldn’t bother doing anything. It won’t return any value to you and you really shouldn’t be seeing any issues relating to rust within 8 years. I’m actually in the middle of treating mine underneath at the minute. Mine is 10 years old and I don’t plan to get rid anytime soon. There is only surface rust present, albeit quite a bit. The body seems worse affected than the chassis. I wish I had a ramp as doing it on the drive is a PITA. I have some photos in another thread in the general section

Have a chat with CC automotive, he advertises on here, he did a very comprehensive on on my year old Landmark, which I also intended to keep for a good few years, but sadly the engine failed at 20k miles and having lost confidence in the brand, I then traded it in, once LR fitted its new engine. Still miss the practicality, but not the uncertainty.

I used Buzzweld on my D3 during its rebuild

Good stuff, gets good reviews, easy to use/apply. I'll see how my own long term stuff lasts, but so far, the only thing tonreport is the WAR topcoat seems to have shrunk a little in places, the R.E showing through a little

Just my tuppence; I've had maybe 8 D3s and D4s and have gone back and forth about doing this. I've had a couple of brand new cars and thought about doing it then but didn't, which is just as well as I kept swapping them out and I'd never have got the money back.

I now have a 2006 LR3 V8 w/100K miles. I've had it 4 years and it's been very well looked after by me and was a 'soccer mum' car before that, with full LRSH and basically over-maintained.

I admit that I don't off-road it (it goes on tracks and camping, but I don't do hobby 4x4 stuff) but the salt in the US where we are in the winter is a HUGE issue for cars. There's a ton of it.

I put the car through a full wash including underside wash and protection every week in the winter. The car has next to no rust (usual stuff on welds, etc) but on a 14 YO car in harsh conditions it's nothing.

Noting that I don't off-road, I'd say spend the money on keeping the underside clean; wash it regularly in the winter and save the money on underbody sealing just because the cars don't need it. If they did, in the salt they throw on the roads here mine would be a pile of brown chips.

Have a look at this thread: -

https://disco4.com/forum/corrosion-prevention-guide-177281.html

I had my Defender done by Chris Calvert (aka Zagato on here) and he did a cracking job.

Going to get my D4 done later in the year after the Covid-19 situation has calmed down.

That’s CC automotive, as I mentioned above, Chris did a fantastic job on my D4 landmark. He advertises and is a sponsor on this forum.

My Old Bus was 14 years old when I sold her. Other than keeping in good mechanical fettle, I did nothing preventative to her and she was the most stupidly reliable car I have ever owned and was in really good condition from the chassis up for her age.

Gerty, my D4, is 7 years old and is also in good form and fettle.

Personally Id look after your car mechanically and forget the rest. Thumbs Up

Bleeding knuckles - Many thanks.

Have a look at this thread:-

I believe that there may well be earlier similar ones.

This seems to come up every now and then but the consensus seems to be.... just say no Mr. Green
