The wear of the engine happens during start ups, when not enough pressure of oil keeps moving metal parts separated.
Short trips at relatively low speeds and frequent start ups can kill any engine many times faster than old oil.
The lubrication system is fed by a pump; hence, as long as there is enough oil level in the crankcase for that pump to suck it up, oil will flow onto all intended parts (even if the filter is too dirty and clogged, because there is a built-in by-pass).
Besides accumulated dirt and carbon from combustion, other potential risk is decomposition of oil due to high temperatures and contamination with gasoline or coolant.

These engines will assertively let you know when lubrication has been deficient, even for short periods of time: they can be either properly lubricated or blown apart.
