Lubrication - Oil, what it does and how
It's criminal. Folk spend fortunes putting together super-sonic motors, only to skimp on the oil they use. Why? Oil's oil right? Wrong. Even if it's a standard engine, it deserves TLC considering it's extremely hostile working environment.
Oil is literally the engine's life-blood. The opening few sentences are astonishingly true. Oil isn't there just to prevent all metal components within an engine fusing together in the first few seconds of running, creating a total melt down of Chernobyl proportions. It's an intricate blending of chemicals to protect the engine as a whole.
The most commonly uttered statement about engine wear is most wear occurs within the first 10 minutes from start up when cold. True if cheap chip fat oil is used.In performance and race engines, a considerable amount of wear is created by heat, load, speed, and pressure. Again, cheapy oil won't give protection here.
