MRV and CCS - Relevant yesterday

[OVERKILL]

We often talk about the relevance of MRV and CCS because most don't experience the temperatures at which they are measured.

Sorry for the poor quality pic:

Yes, that's -30C, which is -22F.

Comically, this is the first winter I've run something other than a 0w30 in the Expedition. This is also IIRC, the first winter it has ever experienced a start this cold without the block heater being used.

Oil in the sump is PU SN 5w30. Being a 5w30, its MRV is measured at -35C, and its CCS is measured at..... -30C

So my 5.4L had to deal with oil that was 4,000cP this AM. The battery wasn't all that happy about it. The Powerstroke parked next to me at the hotel, despite being plugged in, wouldn't go. CAA had to come and jump it. It still wasn't running by the time we left.

I laughed a bit thinking that the oil I changed out not too long ago (M1 AFE 0w-30) would have been about 1,000cP lighter.... Go figure.

We're supposed to have the coldest temps in 15 years here on Monday-and I JUST put a 500W Wolverine pan heater on the F-450, which I'm actually going to have to get started at -10F with 15W40 in it!

Wonder how it would have gone in the 48C that my FIL's Iveco Winnebago had to start in the other day.

Oz is getting record heat lately.

You're still well ahead of the curve -- think about how many modulars have something much more viscous (say, 15w40) in the sump.

Hi,
well now - here in OZ we have a series of heat wave areas throughout and a drought! Its our Tropical "wet" season with no serious rain for several weeks

The max. temp has been near 50C (able to fry eggs on a shovel blade) and in this area where I live in the Tropics we've had several days around 37-40C - at 9.15am now it is 32C

The M1 0W-40 and M1 5w30 fires up well from a cold start here..................

Enjoy the cool!!!

That's probably what was in the Powerstroke, LOL!

My Niece and her Husband left California to go to Minot North Dakota (Air Force) he asked me what oil to use in his 98 ford explorer and I told him he better ask the locals. Was -25F in Minot the other day. C R A Z Y weather for people from Southern California ha ha

This weather is really testing people's batteries. Never been this cold since I've lived around here. Not used to a high that borders on negative.

Yeah, it has me doubting the health of the Exide NASCAR select I have in the Expedition which has a manufacturing date of 2009. With north of 900CCA (when new) it should not have had the trouble it did this AM starting the truck.

 

[901Memphis]

Makes me glad I have my just about 1 year autocraft gold in my Buick.

 

[Rand]

Well you have to factor in both ways

yes the battery puts out less when its colder but also the engine is much harder to start. Gets to where the starter is grunting even with as much power as it could want.

I am very happy I trashed the 285CCA factory battery in my forester. its 5F and falling.. sunday is high 35F rain with low of -3 monday/tues we are going to be in the negatives for a high.

At minus 30 you have around 50% or less of your rated power and this is with a new battery. So your 900cca battery is around 400cca

I bet the BITOG'er in you was a little excited about being able to do a cold start evaluation right at the CCS limit for a 5W. But it could have been worse. Isn't 6200cP the maximum limit of CCS for a 5W?

Yes, yes I was. I saw that temp on the HVAC and was instantly "hey, that's the CCS temperature!!" LOL!

On occasion here we get into the 37-40 range (not 50C, of course!). I can handle that. Heat is not my enemy. I don't even turn on my AC for most of the summer. Our Monday night low, though, will be -36 C. That is hard to handle.

You guys talk about negative C, minus F ... When the thermostat shows anything below 55F I put on a light jacket over the sweeter. When it's below 40-45F we don't go out.

We almost never have any temperature below 30F, may be once or twice every 10 years, therefore any 0WXX is not really needed here, I think we can safely run straight grade in So Cal.

Yeah, you gotta be careful, you might get frostbite

It's warmed up here to 22f and it feels good to unzip the jacket...heck, I took out the garbage this morning in a short sleeve shirt. Felt good.

Monday should see lows of -24F, the local schools are already called.

You can probably run 10w30 in most cars, and buy it cheap on sale when the 5w30 is sold out.

45F is a warm up in March when I wash my car by hand. Can't wait for that heat wave!

An engine block heater also gives the advantages of the engine warming up much faster for cleaner exhaust and better fuel mileage sooner, plus the warm cabin much sooner.

The Powerstroke needed an oil pan heater and a batter heater in addition to its water jacket heater. It'll probably need ether to get it running. The trick with ether (engine starting fluid) is to see how little can be used to get it going. I've seen engines get too much, the ether fires before the piston reaches top dead center, and the piston is pushed down rotating the crank backwards for that stroke. Doesn't work that way....

-30! Wow, maybe time for CATERHAM blend OVERKILL?
