There's no need to go by recommendations, or opinions, or to guess. Somebody said (might've been you) that oil is cheap and engines are expensive; in that sense one could also say that oil analysis is cheap, and you get objective data specific to your vehicle if you feel that helps you. Or you could play 'better safe than sorry' and do what you've been doing, which is fine as well. I'd be willing to bet that Wal-mart's store brand oil and a Fram filter changed every 3K will do the job for most people driving their Hondas and Chevys and so on, given that they picked the right grade in the first place. The waterboxer is a bit more of a particular beastie, of course, which is just another reason to get rid of it afaiac, but it's still not that complicated. I wouldn't get too wound up about what Click and Clack thought of anything in any event.
Cya,
Robert

Well, still looking. I did find that any number of sources consider
taxicab service as "severe," due mainly to the low speeds and long
idling times. The "Car Talk" web site has lots of references to the CR
study, but no link or definitive statement concerning the methods or
results that I could find. Mainly just a bunch of people on their forum
commenting on it, some of whom remember the results differently from how
I do. At least one claimed that the results showed a need for adhering
to factory or more frequent oil change intervals. I do remember that
that was not the case. Oh, I did find that whenever the hosts for the
"Car Talk" show recommend oil change intervals, they still stick with
fairly frequent changes, and do not approve the extended frequency
changes of some manufacturers, despite the results of the CR study.
