After reading: Cold Weather Testing (by Ford) (http://www.grandamgt.com/forum/showthread.php?s=&threadid=28821)

I was just wondering (especially you guys in the 'prairies' Canada):

How cold (air temperature) have you started your car unaided (no block heaters, booster cables, etc...) ?

With what type of motor oil in the engine (& if possible, the border line pumpablity temp rating for that oil) ?


I have started my GA at -30C/-22F (in Montreal, Quebec) with GM Goodwrench 'dino' 5W30 motor oil before (during the 1st winter/year I had my GA).

In Toronto, almost -30C/-22F with:
(North American) Castrol Syntec 0W30 motor oil with a B.P.T. around -40C/F;
Mobil 1 5W30 motor oil with a pour point of around -45C/-49F (not sure on the borderline pumpablilty temperature rating for that oil).


It is suppose to be -24C/-11F tomorrow morning :rolleyes:

i've started my 1987 Oldsmobile in minus 32 degrees Celsius (minus 40 something with the windchill) after sitting outside for about 9 hours without being plugged in. I've started the GA after letting it sit through 6 months of winter without plugging it in too. :D

-30C at home in Kelowna BC after sitting for 3 days on the street. Not plugged in. That was my 4cyl 89 mustang. Started right up! :thumbs:

Only thing you have to worry about when starting a cold car is that the oil is really thick and doesn't move well. This means yours parts will be moving without much lubrication until it warms up. So after starting, either let it warm out or drive very easy (ie. not over 2000 RPM) until it warms up a little. Baging on a just started engine could result in you throwing a bearing. That means expensive engine repair work.

-38 this morning when I came home. Car stared on AmsOil 5W30.

BUT

My wheel hub(s) were frozen.Drove 3 feet and my VSS Error lights came on (ABS, Trac SVS) And, when I pushed in the clutch, the car stopped like I hit the brakes. hehe

Drove a few hundred feet and everthing was fine.

Cold Unaided Car Starts - How cold have you started your car ?

In my GA:
(Early in the fall/winter: Mobil 1 5W30 oil)
(now) German Castrol Syntec 0W30 synthetic motor oil (with a over-sized NAPA Gold [Wix] oil filter)
& a Optima Red Top Battery


-26C/-13F air temperature this winter so far this season.


[With both types of oil; but the German Castrol Syntec 0W30 with a cold start rating down to -40C/F (pour point rating down to -63C/-81F before freezing), definately sounded better cold starting at that temperature.]

-33 or so ... sounds like a dying cow when you start it up that cold

and that was with normal gm 5w30 oil

-25 deg. F when it was rediculously cold in the northeast last year, wind chill to -45 with Mobil1 5W30, and -15 the past few weeks or so, M1 0W30

Grand Am = -27 in Marquette, MI.

GTP = Well, it's -10 right now, and I think that's the coldest it's been since I bought it last September...so we'll see.

Typically I just start them and go back in the house for like 10 minutes before even thinking about driving them.

Wow, mine sounds almost wussy-ish compared to yours....... but the coldest I know I started mine in was -18F and like -26F wind chill. Just regular 5W30 motor oil and it started right up.

-32 -37 no problems. Just creaky clutch, struts and again frozen wheel bearings. :D

-26 so far this year with Castrol GT 5w30

-30 C to -37 C

Do struts normally feel so rigid in the winter? Lots of creaking sounds in the cold.

My car is usually 45C before I drive. Only had to cold start once or twice.

my 1996 grand am 2.4L started with mobil 5w30 in Fargo, ND -43F
-53F windchill always starts right up! when I had different brands of batteries it didn't start as good as the factory battery! got the maintenance free heavy duty sealed ac delco. :ec:

-48C on the street overnight last year. The only problem was the ABS light came on, but it turned off when I restarted the car after about 30 min of running hehehe.

-45f Hard start. She was not happy. Let her moan and growl for at least 10 minutes. Preferable 30 minutes at that temp. Make lots of promisses never to let that happen again.

I'm using 5w30 Synthetic Blend Castrol

But yeah - good times. And also had everything Molson already said for other symptoms.

-36 <-52 with wind> nothin special for a battery or oil

I have heard that wind chill does not affect a vehicle. the metal only gets as cold as the air temp. Wind chill is more for frostbite on skin. Any truth to this?

-53C at work for 9-10 hours. Battery was brand new though......factory battery worked up to about -45C

Yes, that is truth. Windchill only effects things that are warmer than the actual temperature. The car will be harder to keep warm but starting it when it's -30 with 0 windchill is the same as starting it at -30 with -50 windchill.

From: Problems starting car in cold weather (http://www.howardforums.com/showthread.php?t=1475075)

Figures I go answering car related oil questions, in a cell phone forum lol

Wtf :goodness:

DO NOT USE 10W-30 IN YOUR VEHICLE DURING THE WINTER TIME!!!
(Since you live in Montreal, QC.)

You are pushing your luck with 5W-30 dino motor oil at -30C/-22F; & not using a block heater !

All 5W-30 motor oil is cold crank rated to only -30C/-22F; but some perform better than others.
IE: Synthetic motor oils.

You should be using a synthetic motor oil at those winter cold temperatures.
Either in 5W-30, or perferably 0W-30 (which is cold crank rated to -35C/-31F).

I personally use all year round: Castrol Syntec 0W-30 (from Germany) that is cold crank rated to -40C/F, & have an Optima Red Top (AGM type) car battery.
But Note: Castrol Syntec 0W-30 performance synthetic motor oil might be too thick in viscosity for some engines (it is almost a 40 viscosity at normal operating temperatures).

For you I recommend in the winter time (& ONLY FOR THE WINTER TIME), put in: Mobil 1 0W-30 synthetic motor oil.
& a good oil filter like: NAPA Gold (aka: Wix, or also sold as Carquest Premuim Blue) that has a Silicone Anti-Drain Back Valve (rubber ones freeze at that temperatures.)

For car batteries: Nothing beats a AGM (Absorbent Glass Mat) type car battery for cold performance.
They provide more "real" consistent power for starting, & recharge back up faster after starting (like for short trip driving).
I like the Optima (http://www.optimabatteries.com) Red Top batteries.
They can be had cheapest IIRC at Sam's Club & Costco.
My Optima Red Top BCI Group Size 75/35 was $129.99 Cdn at Costco (& there was a $25 Cdn mail-in rebate at the time.)
They also had Optima Red Top BCI Group Size 34/78 for $147.99 Cdn

Note: Your Energizer car battery at 550 CCA (when new) is on the SMALL SIDE!!!
What was your OEM car battery rated at ?
Always get a replacement car battery with the same CCA or greater.
More is better in the CCA for your cold temperatures.
What did your mechanic say about how many CCA was left in your battery ?

I had my older (1-year) car battery tested, when getting (at the garage that I go to) changing a battery terminal connection: & it came back at only half of it's capacity in CCA.
So I changed it out (got a full refund at Costco - their 3-year replacement warranty) & went back to a Optima Red Top battery (I had one before but put it in my Mom's car, & Costco stopped carrying them for a short time for cheap. So I got their house brand Kirkland battery).

PS: Yeah, spark plugs & spark plug wires will make a big difference in starting if they are old & worn out.

PSS: Don't forget to use some IPA (isopropyl alcohol) based Gasoline Anti-Freeze early in the winter season to get rid of any water build-up in your gas tank over the summer season.
& keep your gasoline tank at least 1/2 full in the winter time to keep condensation of water to a minimum in your gas tank.
