Define Minimal Oil Consumption
I always hear that 1 quart in 1,000 miles is normal oil consumption based on industry standards but I can't find any "published industry standard.” Can you clarify what is minimal oil consumption?
-- Thomas Laymon, Rancho Palos Verdes, CA
Oil consumption is very specific to vehicle manufacturer, engine size and design. Even within a specific engine model, normal oil consumption can vary quite broadly based on how the engine was initially built, how it was broken in, and even the lubricant viscosity being used.
