Query on diesel engine

**bigT** · June 15th, 2018 09:32 AM

Recently I heard a Toyota staff said that diesel engine should be turned on and let it run for 30 minutes before the first driving every day.

Is this correct?

Wrong myth again.
With today's global warming caused by increased carbon dioxide emissions, it is most advisable not to run your engines unnecessarily both to save fuel, reduce emissions and reduce global warming.
The engine warms up as you drive hastened by the thermostat and controlled radiator fan.

3 years ago I bought an Innova, nobody in Toyota told this, recently, my brother in law went to Toyota to collect his new Hilux Conquest, he was informed of this, I doubt if this is the information provided by Toyota or it is the staff’s own understanding like people might tell you various theories about charging and using cell phone battery.

Misinformed, improperly trained or rogue service advisors who are not educated about the product which, unfortunately hired without regard to education and experience.

I don't believe anybody would actually say to warm up an engine for 30 minutes. That's such a total waste of time, resources.... and seems like giving a heartfelt finger-salute to the environment.

It's likely he meant 30 seconds, which is reasonable and typically within the time range for anyone preparing to drive off.... Start the engine, put your drink in the holder, stow your things/bag/purse, check the mirrors, check the instrument panel for warnings / fuel level, and then finally buckle up.

i drive out a few seconds after my diesel engine starts.
i have been doing it for over 10 years. the vehicle is still fine.

even 30 seconds seems tooo long a wait...

Old school pa yan. Imagine the amount of fuel you just wasted idling for 30 minutes.

Warming up is not a myth but the method is.

It is not a myth that Cold engine consumes more fuel.

It is not a myth that metal expands as it warms so the sealing of pistons and efficiency of burning fuel is achieved only when it reaches normal operating temperature.

The method i do is to drive off the garage with a cold engine and maintain low rpm and shift early untill reaching the operating temp indicated on the dash, or let the cold engine dumb light estinguish before revving hard the engine.
