Will thinner oils damage your engine?

Just like using an oil with too high a viscosity may lead to problems in Brad's engine, using a thinner oil can have the same result. Oil that's too thin can fail to develop a consistent lubricating film, inviting metal-to-metal contact that causes wear. Extreme stress and heat add to the challenge.
