With such a short time frame, I took the “Shock and Awe”approach and broke out the nastiest picture I could find: A greased TDI that had severe coking and led to engine failure. I followed that up with test report after test report of failed engines due to Vegetable oil. Severe Engine Damage, carbon buildup, rings sticking, lubrication oil contamination and catastrophic engine failure. I rounded off my opening tirade with pictures of a severely coked and scoured piston and a pile polymerized engine oil that looked like Jello.
