Interested in the results of the heater alone @ -35. Seems like the current oil fill really satisfies that 4.0 at sane temperatures.
0 oil pressure for 10 seconds

I have more than one, I think. One gets stuck on the side of the air compressor, where it will be obvious and won't disappear.
littleant: With the oil pan heater and a 0w-XX, you should be more than set for the next cold spell.

Agree and it's coming. be here Saturday and staying for 2-3 days. Thank you
(contacted LIQUI MOLY and asked if their product would thicken and increase the viscosity of engine oil. Here is the response from Germany no less) Thank you very much for contacting us and your interest in our LIQUI MOLY products.
Adding our #LM2009 MoS2 Anti-Friction Engine Treatment into the motor oil has nearly zero influence to the oil´s viscosity. So don´t worry, add it and let the engine run for a few minutes after adding to make sure the MoS2 is mixed well in the oil.
We hope we could help you with our informations. Should you have further questions regarding our products we would be very pleased to get contacted from you again.

I think we've determined from Shannow's testing that "nearly zero" is still in fact significant. Did you mention to them that you were using the product in a lubricant that was below the temperature threshold for the grade? They may be thinking in terms of reasonable circumstances, the temperatures you've been experiencing are anything but reasonable, LOL!

I did overkill. Told them location and day temperatures were running 0 and below. Night temperatures were running -30 to - 40. Even mentioning the 0 oil pressure and oil as 5w30. Did not mention brand maxlife.

A 0w30 would be a good choice. I'm just wondering if the pressure delay was confirmed by a mechanical OP gauge or the factory installed dash gauge? The dash gauges can often leave a lot to the imagination.
The best I could count from start was an 8-10 seconds with no pressure showing. light came on beeping check gauge. A second or two the gauge started to show pressure with a slow rise to 60 psi. There is one thing I forgot to mention. When the gauge started showing pressure the RPM,S dropped and you could hear the strain on the engine. Must have been like sucking a milkshake through a straw.
I understand your concern but you have nothing to worry about. For example, the Cessna 172 aircraft POH (pilots operating handbook) instructs the operator to only shut down the engine if no oil pressure is indicated after 30 seconds in the summer, and ~60 in the winter. I know it's not a direct comparison but both are internal combustion gasoline powered engines using wet sump oiling systems.

Again, only -15C...
Not saying that these are conclusive or anything...and really would like access to something much colder to play with....slow them down to 0.25

Which supports the official stance on this engine and MRV, which is a big issue here. You literally sucked air for whatever period it was until that happened. That doesn't mean you damaged anything, but it was certainly far less than ideal.

First off, there is no reason to add oil additives (lubromoly and the zinc you say you added) to your oil. The Jeep is not flat tappet nor will benefit from additional Zinc and you actually are putting your cat-converters at risk with the Zinc. You may have effected the low temp performance or in other ways effected the balanced chemistry the oil maker did lots of research to provide. With your temp range I would run Full Synthetic in 0w30 or 5w30. Mobil 1, Pennzoil - any would work fine. If you dislike the piston slap noise, try another brand of synthetic until you find one that works for you. What you have now is not working for you in the temps you see. Try Full Synthetic maxlife next time.
I don't how you guys live in that weather.
It was 15 here the other day and I could not get warm.How do you go to work or school and go about living?I don't know how you ever get used to it.
Back in the 60s Sat here.
It's miserable in Texas in the summer but at least you can get around and not stranded somewhere.

Hi Dallas. I hear you. Moved here 30 years ago at 34 and it was easy. Now I'm getting to be an old far* but I like the rural living (200 people in town) Willowbey lake. My hope for retirement is to be somewhere else in winter. Summer's are great. I was driving through northern Texas about 2 months ago. Went from Vermont to Oregon. Oregon to Southern California and back to Vermont in 2 1/2 weeks 8,000.5 miles in 2010 mountaineer. Brutal cold temperatures won't mess with Texas.☺

When I've had mechanical gauges it takes a shockingly long time to build pressure below zero. It's normal. I really wouldn't sweat it.

I get to do this almost every winter weekend!

I'm not sure where you are in TX, but I lived in Dallas for a while and the ice storms there were like nothing I have experienced anywhere else...everything covered 1-2" thick and no salt anywhere to make the roads tolerable. I guess the good thing was that it would usually melt within a week.
We had a Noreaster yesterday and it's hard to say how much snow we had because it was so powdery and it just drifted like crazy...I'd say maybe 16" at my house. I had something to finish in the lab so I worked until about noon, the roads were terrible but I have good snow tires and AWD and most people were smart enough to just stay home so there weren't too many FWD cars with bald all seasons clogging things up. Had my wire plugged in on the too-flat sunroom roof for when we have a melt and I went out to snowblow about 7pm...miserable job and I didn't finish until 9:30 (having one car outside makes it worse), but I had a poofy LL Bean coat, ski pants, waterproof hiking boots, a ski mask, an Elmer Fudd hat, and goggles on to fight the 40mph winds and cold. My new snowblower is a real beast and can easily throw snow 50 feet, but I'm still getting used to its quirks and that slowed me down a bit. Of course, schools had all been cancelled due to the forecast.
Got up a little early this morning to shovel some windblown snow, make a path to the front door, and spread some sand...noticed a screen had blown off a window and forgot to try to retrieve it before I left. Schools were delayed 2 hours to allow time to dig the buried buses out, so the traffic was OK even though I left late. My favorite parking spot at work was about 1/3 covered in a drift, but I just parked in it, anyway, and was one of the first in the office. The roads were generally decent due to our hard working plow drivers, but some of the roads in the heart of the little city I work in were still crummy due to packed down snow from traffic during the storm...takes some time for the salt to work on those.
Like anywhere, you find the tools you need to adapt to your situation and do the best you can!

Oh Duh!! My bad I completely forgot the 4.0L was FT. I had a 2000 and I should have known. My apologies.

Not a problem. You had me guessing. I was ready to Yank the head and check
