It's sort of a holy grail paper for the discussions on BITOG at the present time.
Please explain how you came to this conclusion.
Quote: "The following engine oil deficiencies were observed when operating at 316° to 343°C (600°F to 650°F) average cylinder wall temperature (CWT)"
My cylinder walls, in any of my engines, never get close to this temperature. I'm not sure how they attained that using typical water jackets... maybe they weren't using coolant, or coolant under extremely high pressure to prevent boiling away.
Overall, I feel their experiment was relevant to a VERY high heat engine, but I couldn't duplicate their tests with any of the engines I currently own.
