......I'm bored tonight, so I'll post more and keep this baby rolling.
Like I posted earlier, FWIW, I bought my 2004 Boxster S used, with 25,000 miles on her. I have no idea what oil the previous owner used. I have all of her service records, however, and she had EVERYTHING done at a Porsche dealership. So, I guess she was filled with Mobil 1.
I found the car in Chattanooga and drove her to my Louisiana home.
I immediately shipped the car to Jake at Flat 6 Innovations for the "IMS Solution" and other preventative maintenance.
I got the car back and she was filled with DT40.
I've put 13,500 miles on her since switching to DT40.
She went 5,000 miles, dropping only ONE quart on a vacation drive to Colorado with LOTS of WFO throttle up mountain passes crossing 10,000 feet multiple times.
The car is super strong, and the rings appear pretty freaking oil tight.
So, that's my experience, FWIW, YMMV, Yada, Yada..........
