The common belief is that the bulk of engine wear occurs during start up.
Is that really true?
If so, what would the rough percent of wear attributed to start up in an average engine driven the typical 12K miles a year in a mix of city and hiway use with Mid America seasonal changes.
Third, given the effort we all go to in order to minimize engine wear and assuming start up wear is a significant factor, I'd think more would consider pre-oilers, either the accumlator type or pump type. Is it the mechanical complexity that keeps people away from them?
Thanks for your comments.
