Looking at this "news" from the turbo Buick world perspective, it is not exciting in my opinion from a cost point of view.
Their web site info is based upon an oil change interval of 15,000 miles. this is at least 5 times what it should be for even a street driven turbo car. It may have the necessary additives for engine protection, but the oil gets contaminated just as fast as any oil.
The boost pushes gas, both burned and un-burned into the crankcase at a MUCH higher rate than NA. This contamination build up, especially at high miles, includes acid which is certainly not wanted.
Oil in street TR's cars should changed at 2-3000 miles. Over the years, hundred of oil changes show at 2K miles the oil smell of gas and residual of lots of other junk.
A car that is raced will drastically shorten this interval, especially if leaded race gas is used and high boost. At 30 passes with my car the oil is over due for an oil change that I found out the hard way - almost no oil pressure as the filter was clogged with crud.
It is amazing how much crud is in the bottom of the oil pan, especially a stock one that retains at least a pint of oil that can never be completely drained.
Try this at your next oil change, after it has drained for 15 minutes, pour 1/2 quart of new oil in the engine and see what comes out the drain.
This is why we use the RJC or a modified oil pan so we can drain ALL the oil in the pan. When I change oil, I often do the 1/2 quart "flush" just to help remove any left over crud in the bottom of the RJC pan.
I know everyone wants to protect their expensive engine, but just because it costs more does not make it better - applies to other products too, not just oil.
The best protection, change oil OFTEN, and make sure the oil contains the proper amount of anti-wear additive, or add it yourself.
