Because the upper engine is the last place the oil is usually pumped, would be my opinion, and because the bearing inserts might be able to retain some residual oil film withing the bearing/cap enclosure.
 
Now on other types of engine failure, like over-revving with plenty of oil, this might not be the case, since the forces on the pistons and rods would be huge. Think of that heavy piston having to come to a DEAD STOP a gazillion times a minute and what force that must put on a rod!!
 
I've seen engines run 9-10 minutes with all the oil drained out (junkyard capers). Of course, they start to make noise sooner than that, but they don't seize for quite a while.

"...it could chug along for a while..."
 
Motor died and the car went to it's great reward. Bad bearings.
 
Could we please have a moment of silence?

If it's any comfort, some of the metal will be melted down and recycled, and if your car's molecules don't get sent to Turkey to make teapots for tourists, it may well indeed end up as a 2012 Chrysler or something...or a Kia....

Isnt the 2.5 Chryslers 100hp engine?
 That would explain the blown gasket...

#3538 of 3583 Another question for the brain trust by oldfarmer50

Mar 20, 2011 (3:35 pm)

What would make the "Change Oil Soon" light to come on after only 2600 miles on a 1993 Caddy Deville? 4.9L motor with about 85K. It uses a quart of oil every 1200 miles or so which is not unusual for GM engines. I keep the oil up to proper level.
 
Is there anything I should be looking at or is this just another Caddy electrical gremlin?

''...Isn't the 2.5 Chrysler 100hp engine?..."
 
No, in fact it's was not even a Chrysler engine. The 2.5L V-6 was made by Mitsubishi and had 168hp. Wonderful motor which I hoped to get 200K out of.
 
The gasket on the filter blew because I stupidly was in too much of a hurry to check that the old gasket was removed before installing the new filter.

"double-gasketing" is a common and forgivable human error that one always has to watch out for.

#3541 of 3583 Oil Change tip by kkollwitz

Apr 23, 2011 (9:32 am)

I use old Little Caesar's boxes as a drip protectors when I change oil. The drain pan goes on the open box, and it makes it easy to move the pan by grabbing the box instead of the drain pan.
 
The box won't blow like newspapers, won't soak through, throws away more cleanly...it's just a very handy tool all around.

#3542 of 3583 dexos oil? by steve_ HOST

Jun 24, 2011 (6:26 pm)

Anyone here following GM's new "required", specially branded and licensed oil for 2011 GM vehicles? It's called "dexos" and depending on what GM site you read, if you don't use it you risk loss of warranty coverage for any engine problems you may have.

Yes indeed, our Terrain calls for Dexos spec oil. There is allowance for using non-dexos if you can't find it, but the licensed list is getting longer.
