As a result of my changing employment to IBM, both Kim and I quit
driving our nearly 30K miles annually each.  When I figured most trips
would be around town, not getting the cars up to temperature on a
regular basis, I switched the Subaru at 130,000mi and the Mercedes at
175,000mi to Mobil 1.  Because of the additional expense of the oil, I
extended regular oil change intervals to 6000 miles, changing the filter
every 3000 miles.  I was already running it in both Porsches, the Bus
and the Jeep for other reasons.

These two articles were referenced on  the Porsche list today, and are
an interesting read.
