Both on original motors, never been rebuilt. I am religious about doing oil changes every 1500-2k miles. I do them myself, less than $25 in oil + filter, and about 20 minutes of work.
Take it for what it is worth. That is my personal experience, and I am sticking with it.

Wow, think of the money you could have saved if you'd have done your oil changes at normal intervals. You could have enough money to buy a whole engine if necessary, which it wouldn't be, over $7500 dollars in oil changes.
