yes idling consumes more fuel than restarting but can't kick my old habit...why?

the fact that my engine is turbocharged, i need to wait about 1-3 minutes let oil circulate through the turbo as well as the whole engine. listen for abnormal noises first. check engine vibrations if normal. watch the gauges and warning lights for any abnormality. hindi ko parati ginagawa yung start then drive agad. warm up 3 mins and cool down 3 mins usually.
