Does Small Oil Capacity Matter If You Have A Lot Of Oil Cooling?

Post by nicholastanguma »

Time for another bench racing engineering question.

If using a good oil cooler and giant cooling fins on the jug itself how small could an air cooled engine's oil capacity safely be?

For example: 1.5 liters for a 500cc single cylinder? 1.0 liter for a 350cc single cylinder? 1.0 liter for 250cc? You get the idea.

The air cooled, 4 valve Husqvarna 510 from the 80's was a four stroke thumper that used a mere ONE PINT of oil for the entire engine. It was known as a hot temp engine, but according to Super Hunky himself was of anvil reliability.
