Your length of change interval is the right idea. The oil companies
would like to promote changing oil with as brief an interval as they can
while still being able to maintain some credibility.  My low use
scenario certainly wouldn't shear the oil or load the oil with soot
enough to warrant changing after one year, so, if there is a valid
concern about getting it changed at 6 month intervals, it must be an
additive or two that is/are/might be too low to continue driving without
risking the health of the engine.  The question is, does the oil have a
"time clock" that begins ticking when the oil is poured into the sump?

Maybe I will finally send in a sample of my one year, 3000 mile, oil to
get the final call.
