Late January, 4:45am, 10 degrees outside (-12C). Car's been sitting outside for ten hours. It's facing a 1.5mi trip to the gym where it will be shut off for an hour, then driven the 1.5mi back home and shut off again for an hour, before finally being driven 12mi to work.
Are these frequent cold starts and short initial drives bad? If so, why? All I can think of is the extra toll on the starter and maybe on the battery; condensation in the oil (how long does that take to burn off?); possibly running rick; not sure if the engine faces extra wear since 1.5mi isn't as short as just backing out of the driveway. What can be done to lessen the stress of doing this daily, year-round?
