As a newcomer to the Discovery 4 and this forum, I’m wondering how to define a short and longer journey for these vehicles?
I live in a semi-rural location, 5 miles from the nearest fuel station, shops etc, so the shortest journey I do is a 10 mile round trip. That’s virtually every other day. It’s often a bit further, say 12 to 15 miles.
I would class those as short trips?
The longest (up to now) is around an 80 mile round trip, or 40 mile round trip a couple of times per month.
I would say these are longer trips.
Are these kinds of distances enough to warm up and prevent DPF issues?
I’ve yet to do a seriously long trip, though I want to asap. Maybe a run up to a friend’s house in Inverness, about 550 miles or so from me. That will certainly warm up the engine, and hopefully give me a chance to really appreciate my D4 - if it makes it with no problems……  I’m a Disco 4 believer. What a vehicle!

I’m no expert, but often people on here talk about the engine getting to temperature. So I suppose you could use that to define whether a trip is short or long? If the engine is at its optimum temp. (In the middle on my temp guage) then you could argue that is a long trip. If yours has a DPF, then you need about 15-20 mins of driving for regeneration (depending on speed) when it does it , as far as I am aware. So perhaps a good definition would be , car up to temp then at least 15 mins further driving at speed 40mph plus for regeneration defines short vs long.
Interest to know what our resident experts and authorities have to say. Gary

i would thing so long as it gets upto normal temp on the gauge then you'll be ok,mine takes about 2mls in the summer and about 4mls in the winter unless its cold enough for the auxiliary heater to fire up then its about 1-2mls
i have found that my d3 does not like being started and just moved around on the drive without being driven making it a bit "chuggy" on the next start up but that might just be the 20yr old glow plugs the d4 doesn't seem to suffer the same please excuse any grammer/punctuation mistakes,i'm thick,thankyou
