That's very interesting (and VERY long) article, thank you for posting the link. It pretty much confirms what I was told by the techs at Opie Oils, in that ZDDP is just marketing nonsense and bears very little relationship to the actual wear protection capabilities of the oil.

I haven't read all of it (obviously), but I didn't see anything specifically in regard to oil weight. Could I use a 10W40 oil, or even a 0W40?

I liked the idea of the Valvoline Maxlife High Mileage, because it has extremely good wear protection characteristics but also has additives to minimise oil leaks, which has to be a good thing. What wasn't so appealing was the price here in the UK at over 70 for 5 litres. However, if the oil change intervals could be extended to 2 or 3 years, it looks like much better value. Presumably a full Esther synthetic isn't going to degrade and form sludge deposits like a mineral oil.
