Trust this debate is not going to degenerate into the slanging match as per the other blog which I try to ignore.
Each to his own, many moons ago ago I was trying to sell a market leader top of the range diesel engine oil with potential to extend oil drains, to a urban bus company in the UK.
They had special circumstances and chose to buy a good cheap adequate spec oil with regular early oil changes.
Their argument, which I could not fault, was that they were minimising problems such as soot and fuel dilution, contamination and wear debris.
For me the optimum today is to try to conservatively extend/adjust oil drains to fit in with other regular maintenance procedures, properly conducted with regular oil condition monitoring and buying oil from a reliable sources with data to support spec, approval and performance claims and not adding expensive gimicky lubricant 'performance enhancers'(generally untried by all engine builders).
