Cold morning engine warm-up

[Deleted member 6183]

Given that it happens only 2 or 3 times a year I will just start up and go back inside for a bit while the car warms up and clears all windows and mirrors.

Why would I put very minor wear considerations before my own or others well being?

Perfectly fair point, the car should be a servant not a master. Oil discussions are always contentious and we probably get too worked up about it. The issue almost never occurs for me as the car lives in a heated garage and I do my short commute 2 days per week to work by motorcycle right through the winter so I have nothing to defrost. I just start the engine and go within a few seconds. Being 40 years old it wouldn't do an unattended cold idle even if I wanted it to.

FTFY.

Thank you so much.

Is the quality of the air others breathe not a consideration?

We went out early this morning....~1C, de-icer on the exterior of windows & mirrors, wipe down the interior of the glass and we were good to go in about 2 minutes (all safety bases covered) ......?

Start engine, seat belt on (max 5 seconds), if I can see all around - drive away without any excessive engine revs.

No, it's not a consideration.

No surprise there . I'm OK jack.........

That certainly sums you up.

Does it?

Does it really?

Have you considered that I am fortunate to have some space?

And now that you have had a change of mind and changed your post, I certainly am alright Jack, you could say 'Happy Jack'.

My change was within seconds of the original & I had not seen your response......you must have had your fingers hovering over your keyboard.

Space is space - if you are polluting the air on a remote island, you are still polluting the air.

I almost always let the rpm settle at something close to normal (10-15 seconds) before setting off. The thing is so bl#@dy loud at cold start I daren't move off before then.

I remember car manuals of my cars gone by, which I used to read cover to cover, consistently stating to drive off when safe to do so (windows clear etc.).

I've not seen it for a while mind but neither the contrary either.

I've followed that advice ever since without issue.

Makes you wonder though, why operators of big expensive engines always pre-warm them prior to start up. And do their utmost to avoid shutting them down once they are running.
Or those taxis that reach stratospheric mileages - the ones that run 24/7 with driver changes.
Or why the stated fact that 80% of engine wear occurs in the first three minutes of start up gained traction.

Couple of times I pressed the pedal hard while the engine was cold, forced the system to work harder, broke my radiator fan [emoji24]
Give it a go, usually it's the pump that dies (£757 for the CL500) or thermostat (£158).
Also, not a good idea for the engine itself,you need to warm up the engine oil if you are near zero temperatures
Not to mention the P0128 error codes in ECU module.

On a side note, I was warming up my engine one morning and this lady came over to lecture me about idling my engine and pollution and getting fined

Daily commute, 1/2 mile off the housing scheme, 3 miles to the M8 then 19 miles.
Frost free days, start up, give it ~20 seconds to settle light throttle for first 10 miles, then drive as the road dictates
Frosty days, as above except clear windows after start-up probably adds 1-2 mins to the settle time
Never drive off immediately and try hardest to avoid heavy right foot/high revs for at least 10 miles
Also don't switch on all heavy current draw items in the first min or two, the peak load on the alternator immediately after start-up might not be optimum, no data to prove/disprove but it seems logical, a bit like getting out of bed, just give me a min to get my balance

From Popular Mechanics -

"If you start a cold engine and idle it for ten minutes every day, you stand the chance of diluting the oil with unburned fuel that never gets a chance to burn off. That could cause premature engine wear—not to mention needlessly burning up some expensive gasoline."

It goes against intuition that unburned fuel doesn't easily evaporate from the oil but used oil analysis bears this out. Once the oil is contaminated with fuel, some of it remains until the next oil change.

You all of course drive brand new cars? If not, it matters not what you do...but what the previous owner may have done...and he may have ragged the nuts off the car from start on a -10 morning.

But one would not be exacerbating the wear?

But the damage (if there was any) would already be done. I don't think it's a concern to just drive and go.
