After doing some online research I found a very interesting read on an Australian motoring website.
It contains some fairly extensive and somewhat reliable information done by a guy that seems passionate in the subject.
It may have been posted before as it was posted in 2004 and note that obviously a lot of oils have changed in the last decade.

If the link doesn't work for some people I'll just copy and paste it
