"Honest John" always recommends this to prevent excessive oil consumption in modern engines. He also seems to say regularly that oil change intervals recommended these days are too infrequent, as oil (even synthetic) tends to degrade after 8-9,000 miles. The recommendation appears to be, stick with the original oil up until the first service, to let the engine bed in, then after this, increasing the frequency of the oil change can only be beneficial.
Taking this into account, I intend to get to 12,500 miles (I think that's the UK service interval for these), then change it again, either myself or at the dealer, at about 18,000 miles, then back to the dealer for the official 25,000 service.
What does everyone else think of this?
Being an all alloy engine, pretty rare up until now in diesels, I'm not sure how this affects the overall longevity prospects?
Well done on keeping your right foot light in the past few weeks, I know that the diesel demonstrator I road tested yesterday only had about 140 miles on the clock, but I'm sure I ended up going over 3,000 even on a relatively short run. The sales guy actually encouraged me by using the "+/-" manual change feature at one point. & we took off pretty damned quickly.
I must say though, we were stuck behind someone on an A road at about 50 mph, and this speed car is so quiet, smooth & relaxed, it is incredible.
Even at 70, you are only pulling exactly 2,000 rpm, and the box seems to settle into 5th pretty quick if your driving sensibly.
Just my two penneth worth!

Hi Just
you just hit the nail on the head. The car is so damn smooth & quiet if i did not actively watch my RPM I know that I would be flying !
heres a bit of info that may influence your oil changing plans. I bought a 4Lt of 0w-40 synthestic oil to keep Arnie topped up (used 1 lt in 2600 miles so far), it cost me £33.58
and if you were to do an oil change its going to take 9.5 lt of oil costing you about £64.00 plus filter - ouch.
On a happir note my BiL took Arnie for a spin this weekend (after me telling him about the 4000 rpm bit) and he loved every minute of it. One moment we were doing 40 mph the next we were doing 80 mph, in silence, with no effort, with no fuss. I was expecting it, to him it was a revelation - he had just got rid of his 320i petrol BMW and replaced it with a 520dse, the 300c blows the other cars away for performance - his words not mine !

p.s. my vans at work are on 24000 mile service intervals !!
