Who knew a push mower could get so deep? Dirty oil contains particles. When you put an engine into storage it's dirty oil contacting the moving parts like crank, rod bearings etc. Some extended life oil changes are due to laws which vary state to state. Many late model vehicles especially those with variable timing are very prone to expensive trouble. A proper spec oil and timely oil changes are very important for them! if you have a European car their version of API is ACEA.
