Yes, I grit my teeth everytime but, I've had some cars for 15-18 years and never a problem...I just hate that

It's like everytime she slams the car doors(alot), I squint my eyes and shrugg my shoulders/cover my ears. But, nothing has ever happened to the windows/motors/switches...Nothing!...maybe a little rattling. It's just her way of closing a door...SLAAAAM!!!

Otherwise, she is a very loving, lovely, gentle & happy lady(36 yrs)

The operators manual for my Continental aircraft engine (O-470) states that once the oil temp gets to 75 degrees F, it is then OK to use sustained full throttle.
 
Fort McMurray, Alberta (this is where my buddy used to work):

Search Results: From October 29 , 2001 to October 29 , 2013 - Fort McMurray Airport
Max Temp: 36.8 °C (98.24F)
Max Temp.Date: Jun.27 2002
Min temp: -44.5 °C (-48.1F)
Min Temp. Date: Jan.27 2004
Precip Accumulation: 4636.7 mm
 
In very cold weather (ie, below -15C), I have to warm my truck up for at least a couple of minutes before it will go into gear, tranny is pretty worn out.

On cold mornings, I usually start my truck and let it defrost for 5-10 minutes while I gather up my stuff to go to work...
 
Your car is designed to be turned on and driven - idling only wastes gas and does not lead to truly measurable engine longevity.

As long as you don't try taking your engine into high revs while the oil and coolant warms up, you can operate with confidence in any regular temperature.

Would high revs really be that bad - at least up to a certain point? I suppose the opposite would be lugging the engine, which could be worse in some cases.

That would actually get you a ticket around here. Esp if the car got stolen, and they found out it had the keys in the ignition and was running, unattended, they'd give you the Ticket before they finished taking the report.
 
At the end of the day we are splitting hairs over things like this, especially if you live in a temperate climate. Cars today will die from rust/transmissions/accidents way before the engine.


I would bet a vehicle running 15w40 year around in South Dakota (Highs in the 90s in summer, down to -25 or colder winters) with proper trans/body maintenance will outlast one running the latest high vi syn oil with lack of trans/body care.

Drive your car and enjoy it. No sense worrying about small things like this.
 
i usually let it idle about a min and then put the next couple miles. I never WOT unless its fully warm. by that i mean ive driven 10 miles. My vette will take 10-12 miles to get and oil temp of 150 which is what i like to see before i get into it.

In the winter on any car ill let it idle longer. 5 mins of idle doesn't hurt the engine at all. it does use fuel, but the engine is lubed just fine. most cars run relatively high oil pressures on the first start. my vette runs 57psi on a cold start at 40 degrees F. at a warm idle its at 32psi. cruising at 60 it is at 39psi. For those who believe warm up idle creates more wear because of oil pressure you are mistaken. 30psi is plenty of lubrication for and engine spinning less that 1k rpm's in your drivway.

He musta worked in the oil industry. It's certainly cold up there. I built a house for a friend of mine in fort Mac. Never again.

While we are on the subject of warm up does anyone have any idea at what temp the engine oil would be considered hot enough to stop being easy on the engine and a person can pedal harder.
 
Clevy, I always wait until the oil is at 150 degrees at least. I'm not sure if that's ideal or not, but a trusted mechanic I know recommended that temp before WOT especially if your engine is all aluminum. Basically you want to be sure that heat is distributed throughout all areas of the engine, fairly evenly.

Yup, he did a few different things up there, one of them was driving water truck, which destroyed his back. He's now living in BC, LOL!

I'd say it would be bad, of course, up to a point. Lugging isn't helpful either, but there's a pretty wide sweet spot between full throttle and lugging.

You want to avoid high revs because the oil pump can only move oil through the engine so fast. Cold oil is thicker and doesn't flow as well as warm oil does.

With multi-grade oils you generally don't have to wait all that long unless it's really, really cold outside. You just want to avoid starting the car and pegging it to redline until the oil's viscosity (as determined by temperature) is in the engine's "happy" envelope.
 
As long as your Mom was it? Doesn't let her new TDI idle til it is warm.

That is the quintessential get in and drive car. It will never hit operating temp otherwise!

cold thick oil allows cavitated air to stay entrained in the oil.
 
I have to admit to a growing temptation to let it warm up, so as to defrost the windshield, rather than scrape ice (which can gouge the windshield).
