Hal breaks down the "plain arithmetic" on his legal pad, explaining how thermal and moisture shock can flake away the power-robbing crust on your pistons and valves. He provides a cautious, step-by-step guide to the "metered mist" technique, while identifying which engines are candidates and which modern trucks should stay far away.
