Oil for 2000 Boxster S

[jmatta]

I prefer to listen to Jake Raby, Charles Navarro and JFP in PA...I don't trust the factory recommendations, as they are obscured by marketing deals.

My engine is healthy and there's no clatter at startup, like it did when it was running M1 0W40. Thank goodness it only saw 8k miles before I made changes.

Ditto. I don't trust the geniuses that brought us the IMS and 20 or more other modes of engine failure in an expensive car.

well put. If you refuse to admit, after the fact, that a fundamental and potentially castastrophic design flawe was baked into your engines, then I have a hard taking your assurances on much else. I'll take 'Porsche approved' oil as more of a guide.

Hmm. Aren't those the people who designed the entire engine and the entire car? Or was it that there's an entire, competent engineering team and then one dude at the end of the design cycle adding unreliable parts when no one is looking? And that's the same guy who spec's oils?

This oil debate reads like "War and Peace". After reading through the lengthy article that someone posted from Ferrari-Chat, all evidence suggests that we should be using 0w weight oil in our vehicles . Yes or no ?

I don't specifically know how Porsche does it, but I doubt the guys that designed the engine were the same guys that designed the rest of the car. Car designs are usually split into teams, with someone providing overall integration co-ordination. And each team would have its budget for design. Some parts of cars are strong, and others aren't. In this case the M96 design is weak.

The basic issue in this thread (as in many others) is oil, and I'll trust Used Oil Analysis results every time before "that's what the manufacturer recommends".
