Hey Scotty, you always talk about when a car runs lean it gets better gas millage, but does running lean cause any wear or damage to the engine?

it's not good for the engine or exhaust. And I don't believe you get better mileage either, because the engine is not running at optimal efficiency. I sure don't.

Lean mixtures run hotter. You can burn exhaust valves.

An engine running lean will burn the pistons. The perfect air/fuel ration of 14.7:1 is the computer's job and it adjusts it to as close as perfect as possible under varying driving conditions at about 30 times per second.
