-24 Degrees C

[Turbodriven]

We bought a new Bosch deep freeze the other day, so before the wife could fill it with meat I loaded all my new oil samples (I take a 50ml glass bottle sample of all the oils I have in my stock) in. Set the temperature to -24 and left it overnight. Not that this is scientific or anything, I was just curious.
The Castrol SLX Longtec 0-30, Mobil 1 0-40, Fina First 5-50 and Fuchs 5-40 were all still very fluid and flowed well in the bottles.
Interesting that the Motul 300V 4T 15-50 was also still flowing well, but not like the others above.
As expected the Bel Ray 20-50 semi synthetic hardly moved when I turned the bottle upside down.

Tonight I am going to try some gear oils...Castrol MTF 1067+ 75-85 and Mobilube 75-90...I will keep you posted.

Don't need a freezer around here to test oils...it's cold this morning

Will be interesting to see some Group III oil compare to Group IV Syn.

I put some 10w30 in a butter dish and left it out side one night when it was -39. The next morning you could turn the dish upside down and the oil would stay in the dish for over a minute.

It would've been the perfect night for me to put some oils outside last night, as it was the coldest night we've had all year, at -20C (-4F)

I have my mom's 2001 Golf right now (I borrowed it since I didn't want to drive the Corvette in the snowstorm we just got over the last couple of days) and it has GC 0w30 in it. It cranked over pretty slowly this morning but once it fired up it didn't make any strange noises. Her battery is probably nearing the end of it's life. The one thing I like about this VW is that even on such an extremely cold morning, the idle doesn't shoot up super high. When I fire up my wife's Honda on a cold morning like this, it's idle immediately shoots up to 2000 rpm and stays there for a few seconds, then comes down and holds at 1600rpm. In the VW, it only shoots up to 1200rpm, and only for a second, then settles at 1000rpm. That super high idle on the Honda definitely isn't the best thing for engine wear on a cold day!!

FWIW, even in such cold temps, I did not idle the VW for more than 10 seconds before pulling away. I kept the rpm below 2000 for the first few minutes, and the engine did not make any funny noises at all. I still for the life of me do not understand the obsession so many people have with warming up their engines before pulling away. It's simply not needed.

It's been as cold as -13 here in Ames, and my 96 Audi A4 hasn't made any weird noises starting (except for the alt bearing) with QTP 10w30 in it.

Personally, I hate driving a car with a cold interior.

I also don't like it when the windows fog up and I'm forced to make rational driving decisions based on the 4"x6" clear spot at the bottom of the windshield.

I also dislike the high idle that occurs while my truck is warming up, which tends to continue driving my rear wheels even when I'm pressing the brakes.

I'm not so sure for a 6K+ redline engine. It may be the case that needed lubrication reaches critical components quicker and helps establish hydrodynamic lubrication. Kinda' like breaking-in a flat tappet SBC/BBC. Anything less than 1800 RPMs when first started is not a good practice.

 

[Shannow]

427Z06, yeah, I tend to agree with you

When I start my Honda on a cold morning I've noticed the same, it revs up to 2200-2500 rpm for 1-2 seconds.
The digital rev counter also is kinda slow (liquid cristal display) so yo can see a trace of how high the revs have been.
I am a little worried about those cold start revs and never understood why Honda allowed it and figured it had to do with warming up the cat quicker for enviromental benefits.
After reading 427Z06's reply I feel a bit better as it may not be that bad, more revs = more oil flow.
I will continue using 0w30 though.

That's your torque converter and brake proportioning valve in action there on a low friction surface. Happened to me all the time with my 454 pickup in slick weather. Sitting there and the tail end would start sliding around. Took me a bit to figure it out. A firmer foot ..or putting it in neutral works well.


..but..you gotta do what works for you in terms of the warm up deal.

Good point that I forgot to mention...the importance of using the factory recommended grade and certification, unless of course, you know how to do better.

 

[Syntec-Man]

MY honda does the samething too it shoots up in rpm for 10secs and it slowly works its way down. I have been told that it does that to warm up the car quicker!

The windows did not fog up on me one bit this morning, and the interior didn't feel all that cold, I wasn't even wearing gloves or a hat. This Golf has seat warmers, but I forgot all about them and even when I did turn them on I only put it on the 1st setting. My Corvette has leather seats with no warmers, and it's pretty cold when you first sit on them, especially in dress pants, but it doesn't take long to be comfortable (under a minute)

With windchill we have seen -30C and below at times in T.O.

I concur with Seth. I live in Southern Ontario and it got down to -19 C last night. It was the first time that I have heard the starter on my Honda Civic Hybrid! The IMA system usually starts it up. It must have some feature that if it gets to a certain temp, then the regular starter will kick in. Good thing for 0W20 !

Sh1t a brick that is cold!!!!

I guess you don't need a fridge.

Maybe get hold of Brian for some of that 0w-10 oil....
