i was impressed..i am running Pennzoil Platinum 5w20 and it was cold as [censored] last nite in NH but the engine turned over easy...it is a good idea to use syn i winter
 
+1 ur oil will let the engine turn over much more easily, and get to where it's supposed to go so much faster. many people mistakenly believe that a 5wxx oil behaves like 5w no matter if the xx is 20,30,or 40 or even 50. but always 5w20 is thinner cold that any of those others. ALL multigrade oils are a compromise, in one way or another, which is why i like to look at the data sheets given by the manufacturer.

You are sadly mistaken. I don't even feel like explaining anymore.
 
It was -20oC (-4oF) in my part of Canada last night and my truck started up with no lifter tick at all and very easy with PP. First time I have used it and I'm impressed too!

I was up in your area back in the late 90s for an intership when you guys had that crazy cold days of -50F in the very early morning and then things tend to warm up to around -30F around noon time. My buddies and I had a awd Corolla wagon with Mobil 1 5W30 in it. That wagon started up right away each morning. While I like the super cold area to keep the Beowulf cluster running smoothly, I always thought our car didn't like being turn over in such a cold climate. A lot of people put hot coals in a metal can and place it directly under the oil pan for 10 minute and some even had those fancy engine block heater with extension cord running back to their front porch. Our car started up fine with just Mobil 1. My buddy still has that car, which reside in peaceful and dutiful life in west Texas. It has almost 400k miles on it the last I went down to see him.

Do you use engine block by any chance.
 
You mean -50oC -50oF would be too cold to even think about starting a car. I have started my old car with conventional 10w30 at -50oC and it was brutal. It sounded like a fork in a blender!

I remember hearing conventional 10w30 in -30F temps, and it was not a sound that I would call pleasant, or good for the engine. 0w-xx is the ticket when it gets that cold.

I just checked the record for Ontario... -58.3 C 23 January 1935, Iroquois Falls, Ontario, Canada

Back then cars would be frozen solid for sure!

where's the xanex when you need it ???


Got it right here.... It's the only way I'm able to sleep at night.
 
google is ur friend: just go quaker state viscosity, and the following shows right up, it's number one, you don't even have to look far:
------------------------------------------ 5w20 ----- 5w30
CCS Viscosity, cP (°C) ASTM D-5293 4,790 (-30) 6,100 (-30)
MRV viscosity, cP (°C) ASTM D-4684 12,100 (-35) 19,100 (-35)


notice how both oils are 5w. see how fast the 5w20 runs compared to 5w30, at temperatures that actually regularly take place where i live. alright, please explain how these manufacturer measurements are so "sadly mistaken" can i take my xanax now?
 
It's been a bit colder than that recently in Chicago [-15 or more], and my Motorcraft 5-30 just let's the car start almost immediately, pretty much like in Summer.
The exhaust note is different in really cold weather - starting or driving.
Fuel injection is great for proper fuel amounts and atomization .
