What do you mean by cheap stuff? Long life oil is not just more expensive, its has completely different characteristics
Personally i do not want my Ed30 on the long life servicing. I would rather have my oil changed at 10k max. If you do some research you will find long life servicing is not recommened for every application. Long distance driving with realitively low rev's is its main market, where as i imagine most ED30 drivers give it a bit more revs from now and then.
Anyway, not saying one is better than the other, just saying there is a lot of information out there giving you something to base your decision on
