I was also told 10,000, I just had a look at my diary where I wrote it but was told 12,000 would be fine. And yes Kilometers not Miles.
It was Trivetts.
I am led to believe as someone else said it may have to do with climate and definitely dependent on type of usage.
Might just quickly add that I did 2 oil changes on the Defender. One at about 1500kms or thereabouts and then one at 6,000. I know people say that periods can be extended due to good advances in oil but I do feel initial changes while the engine is new are still very important and then 20,000 is to far no matter how good the oil. I basically wonder if all this has been changed to cut the companies cost as first service was always free anyway and then it looks better running cost wise if your booklet says you only need one (rather expensive) service Per annum. Of course this is just my opinion but especially on engines which don't use Delvac 1 oil changes are pretty cheap.
