Yup good call.
New filter is on my front seat.
I've seen a few sucked apart...usually the orange Fram.
I have a NAPA filter on it now. Will look inside it, like I do all oil filters I take off.
Also -40f!?
Feel for you!!!

 

it couldn't be more than a week ago I saw a video of a bunch of filters cut apart, those orange fram filters with the black grip on them were the worst there was. The best was napa gold.

and yes -40. Got a new block heater though and fires up instantly as long as its plugged in a few hours. Oil pressure a second or 2 after firing, zero issues I can tell of

 

i switched from 15-40 to 10-30 in my diesels. they start a lot easier in winter, and do not have any issues in summer.
my 2014 6.2 engine uses 5-20 semi synthetic.

 

We've been at or below -30c here for 3 weeks, I run rotella t6 5w40 full synthetic and have never had an issue starting. plug the old girl in and even on the one morning of -45c she fired right up on the second crank. I would never run conventional oil are these temps.

Glad you got her lubed up.

 

What's wrong with conventional oil? I've always used conventional oil and sometimes even some straight 40 mixed with 15w40 or I'll use 15w40 and top up with 40 weight.
If the block is warm to the touch from the block heater, I don't see the issue.
I've never had an oil pump failure or anything like that. Engines have all been in good condition as well when I got rid of them.

 

Nothing's wrong with it but whenyour in the bush with no where to plug in I'd rather have easy starting with a thinner synthetic than conventional oil. Go start your truck at -40 without a block heater and 15 weight, I just did it last week, let me know how it goes.

 

nothing is wrong with conventional oil, that is all i use in everything except for the 2014 6.2 engine. i just switched from 15-40 to 10-30 for easier starting in winter.

 

A while back when Blackstone published those old comparison charts and synthetics showed no real reduction of wear, I thought screw that. Obviously there is a ton of advertising money for synthetic oil.
the only value in synthetic to me seems to be starting if you're not plugged in.

 

Update:
Absolute mystery.
Filter was fine and it has never done it again. Engine seems happy enough and the gauge reads right where it always did (FWIW).
Oil pressure pops right up immediately on startup every time.

 

If you drove a mile with zero oil pressure, the motor would have been trashed.

Maybe your regulator stuck and you were only seeing a few pounds, or your gauge was faulty.

Starting is the hardest thing on an engine because of lack of lubrication, so I don't see how it would have survived that, not to mention the lifters are hydraulic and it would have ran like absolute garbage popping out the intake and exhaust.

Glad to hear its all cleared up now!

 

Oh it was bad!
Was running on about 5 cylinders and actually locked right up....completely!
I thought she was a gonner.
Drove about a mile with a 9 ton trailer and it was idling while I loaded the machine so I didn't hear it happening. I wanted to punch myself in the nuts!
Still can't believe it runs.
