I change the oil & filter on my two classic MGs every 12 months or 3k miles.
I am concerned however about "over servicing" my Disco4 if I follow the manufacturers recommendations.
Pre-Covid I was doing about 11-12k miles per annum in the D4. In the last 2 years this has come down to c.5k miles p.a. Question, should I slavishly follow the LR recommended service schedule - which I must say I'm inclined to do.
Should I drain the ADBlue, as the rate of consumption has dropped so that I am aware it may start to crystallise.
What other thoughts regarding servicing in these different days?

For the last 30 yrs I have changed the engine oil in all my cars at 5k.
Adblue I would say leave, the makers say shelf life of 6 mths, but no mention of how long it lasts once in the vehicle, I can tell you first hand we have some mothball trucks where the adblue is well over 12mths old.
Does he d4 adblue tnak have a drain cock/tap/bung? the trucks do.

It's a juggling act I know, but condensation becomes a bigger issue when tanks have minimal fuel in, including adblue.
My first adblue truck (DAF) new in 2009 suffered from adblue injector problems due to availability across Eastern Europe. I ended up carrying a spare injector with me, and although the truck has long gone, still have it!

I dont see how adbue would suffer with condensation in the tank ,and have large vehicles with ad blue that stand still for 46weeks of the year with no issues it will not settle out and any crystallisation in a dry environment like the inside of tanks immediately goes back into solution when it comes into contact with moisture.. Modern fuel is a different proposition all together and never go anywhere without a spare set of filters due to mould growth in the tanks caused by biofuels being hydroscopic in nature.
The question of over servicing is another mine field altogether ! This will be very difficult for some to understand but the manufacturers of large industrial diesels actually discourage intermittent oil changes ,because they argue modern lubricants are more than capable of maintaining performance over in excess of the recommended interval and the risks of damage to engines from running empty of oil even for a short period far out weigh any perceived benefit .

I would like to say the Dafs have gotten more reliable!

20 years ago I ran a Vauxhall Cavalier 1.6L diesel to commute to work. Daily round trip 60 miles. Changes the oil and filter every 3K myself. I wasn't competent to do anything else. Had a decent indy do every 15k miles with whatever needed doing.
I took that car from 96k to 246k and had no problems at all.
I am not sure you can over service a car?
D4s I have owned have always been serviced on schedule and my previous one I took to 96k on manufacturers service intervals without issue.
I own my own D4 now and change the oil and filter every 5K.
Again, is it possible to over service?

I have still got the tools to time the cam on them vauxhalls in my garage somewhere!
No I dont think it is possible to over service a car, or there being any downsides to over servicing?
