Hi all, long time since I posted here. What are your opinions on the best method of warming up a car motor (petrol/gas), either with a turbo or naturally aspirated? Some say, start idle for 30 seconds and drive moderatly, others say start idle for thirty seconds and then bilp the throttle for a minute then drive. I don't think the start and idle till warm warrents discussion as I am quite sure this isn't a good method. I would appreciate your thoughts.
