OTOH, by the time I'm pulling out of my parking lot in the morning, the Camry is putting out heat, not much, but warm air is flowing. 1 block later, at the traffic light, I'm turning the heat dial lower.even thou your temp gauge, if you have one shows warmed up quickly oil takes a while longer depending on ambient temp. a casual 15 min drive from girlfriends house in a NA jetta to mine for an oil change oil felt barely warm!!!!
