He could have used plain conventional oil past 5,000 miles in heavy city driving (the worst kind for your oil) and over time, it can gunk up an engine and even kill it. Where on the other hand, someone can be putting mostly highway miles on their car using synthetic oil every 10k and the engine be perfectly fine.
