Vardar

I had several turbo cars, and last one was Saab 9-5 turbo. It's just a habit, I still warm up the engine about 30-45 seconds(maybe even more) before I go to work and stuff. Am I doing good or just wasting my time? I just wanted oil to circulate in the engine a little bit before I take off. Long time ago, someone told me that it's always a good idea to do it.

So, is it good to warm up the engine for few secs, or a cause of the technology these days, we don't need that anymore?

Thank you

when i start my car for the first time. i always let it idle till the idle automatically drops to normal then i drive off.

You may call me crazy but I always worm it until the temperature reaches 40deg (about 3-4 mins) then drive slow untill the engine reaches the normal operating temperature.

If I recall correctly, the reasoning behind warming it up is to reduce blow by. When the pistons aren't heated up, they allow more exhaust to blow past the rings thus deteriorating the oil faster. I don't think synthetic oils are as susceptable to this, but I still warm up all of my vehicles before I drive off.

there was a report a few years ago that went on to interview different manufacturers

germans prefer to warm up as u go. easy pedal, keeping rpm around 2000. at least on the c36, the rpm is kept higher and shifts delayed during the few minutes after cold start.

japanese prefer u warm up prior to going. a few moments at low rpm. let temp rise with rpm held around 2k as well.
