Their cost vs Porsche oil change cost at a dealer is pretty low. Also nice is their analysis of engine wear based on elements found in the oil. For my Lexus, an oil change is only $55 at Toyota which is why I just did one analysis and just did a change at 7.5k. With Porsche being so high, an extra 2500 miles is worth more than the Blackstone cost.

I have not had it analyzed but plan to. If you do the oil change yourself, it's about the cost of your Lexus oil change experience and you get to dink around with the car, which I consider fun. I agree with Georgeair that the analysis is the logical thing to do but I see no harm whatsoever in changing the oil more frequently until the analysis.....

High sales volume should not automatically equate to better quality. It depends upon your own design and the parts manufactured in house and sourced from outside. Quality control.
Most high-volume auto manufacturers use Lean Six Sigma to continuously improve efficiency, reliability and reduce waste.

If you haven't been exposed to it before, FMEA is particularly interesting:

Given the complexity, our vehicles are amazingly reliable! But it sure didn't happen by accident.

Nah, man. It is all in proper diet - good bratwurst and good beer make a good car. Otherwise, Detroit would have owned the world by now (and they DID try) ... ;)

All joking aside, I admit my personal allergy to seeing American managers jump on any bandwagon passing by as long as most of their peers are jumping on it too. That makes for a great CYA skills, not so much of a skill set when it comes to manufacturing. My toys are paid for by being involved in extreme automation in a very narrow niche of manufacturing and I can tell you that, right now, all Lean Six Sigma black belts and all, average American business is best served when presented with a system that has asymptotic towards zero automation content - at least in that specific niche. Pages long "why" treatise does not belong here.

Back to the original joke, much of it is in the head of EVERYBODY involved, not just shot-callers. If pessimism would be required in order to succeed at something, you can be darn sure Americans would suck at it. They just don't have it in their heads and you cannot teach it. I hope I explained what I meant.

Sorry all, end of off topic, back to topic.
