Remote start keeps me warmer...they can come after me if they don’t like it!
Pry from your “cold” hands, right?
Put a block warmer on the car, and an engine oil warmer for the oil in your oil pan - and a high-amp battery to assure winter starts. Once you start the car, begin moving almost immediately, SLOWLY, until the various lubricants get circulated and sufficiently fluid. Fuel-injected cars start much more easily than older cars with carburetors, and the engine management system automatically compensates the necessary fuel richness for the temperature.
Also helps like all get-out if you can manage to keep it in a closed garage between trips.
I remote start my car immediately after I turn it off so it stays warm while I’m shopping or where ever I’m going. I try to go the general area the car is parked after 20 min. if I can to re-remote start it. I like it nice and toasty when I get back in.
