So my brother-n-law recently visited and was asking some interesting questions about some of the techniques I use. He works at a lumber mill in Oregon, specifically he is a mill wright. So he professionally does maintenance on heavy duty machinery. He is not an apprentice, he is a fully certified mill wright. A lot of his questions center around diesels, but overlap to gasoline.

1) Grille blocks, engine heating in the summer, engine insulation. He claims that higher temperatures for longer times is reducing the lifetime of the engine. He says that the higher temperatures actually change the molecular composition and weakens the metal.

2) Running thinner lubrication. He says that thinner lubes essentially run like water, increasing friction. So this adds excessive heat, which due to thermal expansion increases friction again. All in all, greatly increases wear.

3) EOC. Wears out batteries, wears out starters, wears out cooling system, wears out engine.
