Well, the planets aligned and I found all 4 cars needed oil, filter, etc. I did the Ridgeline, the Macan GTS, the Turbo S and finally, the most involved of the 4, my Six.
On the Six, draining the engine and oil tank (you have to separate the oil line from the tank to the engine and it is not an easy location to work in) and then of course, 2 oil filters (one on the oil tank console and one on the engine, is a bit of work. Drained 10 quarts out- I can't really drain the oil cooler and cooler lines - I suspect they hold about 2-3 quarts. But I do the oil and filters every year and probably average 4K miles per year in the Six. So not too worried. Anyway, that's done and she is ready for a fun season. Cheers everyone. Michael
