In Reply to: Survey: Plan 15k oil change vs. Less than 15k. posted by If less, @what mile? on October 21, 1999 at 12:07:41:
Had oil analysis done, showed oil still good at 10k, had another done at 15k, still good. the indicator shows I should change at approx 18k, so I will follow it.
Have 31k on car now, and it's still getting better :)
