Agree with most said in the article you linked.
The oil I've been using and have been happy with is the 7100 Motul 10w40. Like this one:

It costs around 40-45 euros per 4 litre bottle. I guess it's not really MUCH better than Silkolene full synth bike oils, just Silkolene haven't bothered to test their oils to higher standards (it costs). If I didn't get discount for Motul, I'd go for Silkolene, Bel Ray, or any other decent full synth oil.

Most things done in a hurry need to be done again - patiently.
