On the one hand you say it's all marketing, and then you go on to explain that engine technology and oils have actually gotten better. If engine oils and technology have really gotten better (which I agree with), would that not be the reason why Toyota can recommend longer service intervals instead of having to resort to marketing? My lux is a 2007 UK diesel, and I've followed the recommended oil service intervals of 10.000 k's, without trouble so far. The marketing arguement sounds a bit weak to me. Solely because from a marketing point of view, it doesn't make sense to market your engine to be serviced at 10.000 k's, only to have it fail in customers' hands way earlier. That opens a company up to law-suits.
And also, why are you mentioning the EGR as being there to filter out the soot in the oil?
- Firstly, the EGR system isn't down in the sump.
- Secondly, the EGR's purpose is to bring NOx levels down. Toyota's implementation by nature actually re-introduces soot into the system.
- Thirdly, the DPF is in the exhaust system, after the catalytic converter**. It's purpose is to filter diesel particulates to prevent them being blown out into the air we breathe. How is it helping to keep engine oil clean?
** edited the location of the DPF for better clarity -

Having said that, the very next service it went in for, fuel filter was one of the things they marked as having replaced (whether they actually did i have no idea).

It isnt and is only replaced as and when the solid (not flashing) filter light comes on indicating its full.
