NOTE: Under certain conditions, the operating temperature of four‑stroke
outboard engines may not get hot enough to evaporate the normal fuel and
moisture that accumulate in the crankcase. These conditions include operating
at idle for long periods, repeated short trips, slow speed or quick stop‑and‑go
operation, and operating in cooler climates. This additional fuel and moisture
that collects in the crankcase eventually ends up in the oil sump and will add
to the total volume of oil that appears on the dipstick reading. This increase in
oil volume is known as oil dilution. Outboard engines can typically handle large
amounts of oil dilution without causing durability problems. However, to ensure
extended life of the outboard engine, Mercury recommends that the oil be
changed regularly following the oil change interval and using the
recommended oil quality. It is further recommended that if your outboard is
operated frequently in the conditions described above, that more frequent oil
change intervals be considered.
