If they would have let me design my 996 TT "S"...

Oil samples are evaluated (Blackstone) because just like blood, the normal things that need checking can't be checked with your eyes or your fingers.

i guess the dipstick gives me tactile confirmation of the oil level. Plus,it has the added benefit of getting you out of the car and in the engine bay.
The HUD system on the BMW was primarily useful in keeping your eyes outside the car, it projected the information so that it appeared to hover on the hood about 3/4 the way down. I found i used it the most on the freeway traveling at high rates of speed.

There is a reason why Porsche places the tach, and not the speedometer, in the center of the instrument cluster.

Those Blackstone oil sample tests are interesting. People get them done, look at the results and what? Tear the engine down because Fe levels are high? I expect most would say "oh dear" and wait for failure - so what was the point?
Or am I missing something? (Admittedly the engineer in me would like to get the tests done anyway!)

Good question. I suspect many (I wouldn't be part of that group) would at a minimum obsess over the high Fe levels, and some (again, not me) just might go from changing their oil ever 3k miles to every 1.5k miles.

I became aware of the oil analysis program in the late 80's as part of a engine TBO Guarantee for my Telydine Continental TSIO 550 engine. The basics of ail analysis is establishing a trend with samples of oil taken at regular intervals, and in the same manner. Say, when the engine is warm, every 1000 miles. The analysis of the oil then indicates what is wearing, and at what pace, and if there is something to worry about. Thus, an oil sample that showed a gradual increase in a particular metal, like Aluminum, would indicate premature ring wear. Other materials, such as FE, Chromium, and steel all indicate different components. Again, it is not so much the single sample as it is the trend of the samples.

I fully endorse an oil analysis program for aircraft. On cars, not so sold on the effort.

Haul trucks - big $$$ saved by predicting and preventing failure. Airplanes - same plus less risk of falling out of the sky. Your car - probably going to wait till failure anyway.
