None,zilch.....

There are many that comment on New Defender threads that dont own them.

Anyway,thanks to the people that thought my post was interesting and informative.....

If you bothered to read what I wrote you would agree that I found it interesting just not relevant to the topic...that's all.

Some people come here without your perspective and want to know about the options for the new Defender....that's the topic!!!!!! Not DPFs
If you think DPFs is an important subject for 663 owners (as is Adblue) then raise it as a thread! Don't tack it onto this one!!

It's that simple!

Please do that (and stop picking on the moderators for doing their job.) Because it's not about you it's about AULRO!

This is hard to do in city driving, which is why the general recommendation is to jump on a highway and drive an hour before turning around and heading home, at least every fortnight or so. Ideally make that trip worthwhile for some reason other than maintaining your exhaust system

City driving is also the kind of driving that creates more soot to clog the DPF in the first place.

High exhaust temps are one side-effect of very efficient combustion – extracting maximum thermal energy from the fuel. Engines would run like that all the time if it weren't for the fact that those same high temperatures cause nitrogen gas to also burn and create nitrous oxides that are enemies of human health and atmospheric stability. So while clearing the DPF you'll also be chewing through the AdBlue that gets sprayed into the exhaust post-DPF to neutralise those NOx's.

So it's up to you: if you can't see yourself routinely cruising down a fast-moving highway at least a few hours a fortnight, that would be a point in favour of the P400.

Thanks for explaining how DPF works, given our short distance driving petrol seems a more suitable option.

My last vehicle was diesel - but I went Petrol for my new Defender.

Thanks all for sharing their experiences.

One more question for petrol it's recommended 98 to be used. Recently i have been on a trip to Monkey Mia. I noticed that 98 is not always avaliable if you go for long trips. In that case does the warranty get affected if you use lower grade petrol, and does it create any long term issues on the car.

Any suggestions on negotiating price aswell.

I usually put 98 in mine but it runs fine on 95.

LR will not allow the dealer to discount the car.

However my dealer did discount options & dealer delivery…

May i ask what engine you ended up with & the real world fuel economy are you getting?

P300. I do a mix of city and highway driving. Getting around 11L/100km.

10,000km in - it might get a little better over time but not by much.

Cheers,
