Q: My dad was a mechanic and instilled in me that I should never start and then turn off an engine without getting the temperature gauge to at least register some heat. This is to keep totally cold oil from clogging up the pistons. However, my service manager says this doesn't apply to newer engines. What say you?
A: Unheated oil? Clogging up the pistons? Where do these things get started, anyway? From the top: Shutting down an engine that hasn't reached operating temp will have zero short-term effect. As far as warming up an engine before driving away, that old nugget no longer applies because modern engines have better lubrication, tighter clearances and, in general, are more resistant to sludge formation. Start the motor, buckle your seatbelt, adjust the mirrors and drive off at normal speeds.
