For years I would run a blend of Driven's DT40 and XP9 to give me a streetable race oil in my daily that I would track :-)

I know that when we were doing development with Driven on DT40 that increasing the ester content increased oil consumption, but this also was affected by what brand of fuel was used and if it was summer vs winter blends.

From doing research on this topic and some conversations with my shop, they are suspecting that some cars might be suffering from stuck rings due to carbon build up around them, especially the oil control ring. This in turn allows oil to get into the combustion chamber causing it to be burned up. Pulling your spark plugs might show if they are covered with carbon or relatively clean. With many of the cars changing hands over time and experiencing less than idea oil change intervals of 10k miles or so, the built up carbon starts to harden and requires some additional intervention to be removed.

You can't go wrong with The 8100 X-cess 5W40 or 300V Power 5W40. The only downside to 300V vs X-cess is cost- also if you care about having an approved Porsche oil, the 300V will not hold an approval. That being said, 300V will virtually outperform the X-cess in most testing measures with the exception oil change interval length. So if you follow the factory recommended ODI's, the X-cess is a better bet as it has been thoroughly tested to meet Porsche's long drain standards.

If you want higher power output (engine dyno proven), more reliability and better overall oil performance, 300V w/ EsterCore technology is an obvious choice. As far as grade goes, we make 300V available both in the 300V Trophy 0W40 and 300V Power 5W40 that is suitable for most Porsche applications. You can step up to the 15W50 if you have high fuel dilution or high oil temps.- Nick

For mixed driving (track and street), being more conservative will be a good practice- I'd recommend draining at 3,000 miles and see what the UOA looks like. Then you can really make a good determination in how to proceed with your ODI's.- Nick

It is marketed like it is but I am confused given your statements above talking about street driving and 3/5K mile change intervals. Also I pulled an oil analysis of it and the moly levels are much lower than I would expect in a true racing oil. Thanks for the information you have provided this community.
