Hi guys
Changed my oil today has I do it every 6 months
Just wonder how often should the fuel filter and also the diff trans oils be changed on
A 2006 (9 years old) RRS tdv6 it's done just 67,400 miles to date

Thanks

Officially:

Diffs 150k 10 years
Transfer Box 75k 5 years
Transmission 150k 10 years (This is vastly inadequate. ZF suggest a flush at 50-75k which is much more appropriate.)
Fuel Filter 30k 2 years



I change my fuel filter every 10k ~6 months (though I do see this as a little overkill; yearly might be better, but I still do it for peace of mind). Since having a new TC, I will be changing the ATF yearly from now on (20-25k). TF Box I've decided on every third service, so 30k ~18 months. Diffs I'll probably do periodically.  Visiting from DISCO3.CO.UK
