Ha, half@$$ has been disabled. Planning to send the DOD/AFM to the gates of hell soon physically, not just via override. I’ve never waited that long for hot oil check. Just surprised the manual called for a min 2 hour wait. My Eco-diesel took some time….

You need to wait 15 minutes with the oil at operating temperature for an accurate reading. It is usually accurate with less time but if you’re looking for consumption or fixing to add oil, you need to wait for it to be accurate. The 2 hours is if the oil is not at operating temp.

... checking oil level: manual says wait a minimum of 2 hours. Anyone test this theory?
I waited an hour (after a 10min commute to work for flat area to check).
Didn’t see any difference at 15, 30, 60min, so I doubt 120min is going to make a difference. Thoughts?
To answer this question directly, may I put it in other ways?

How long does it take for a 212F-oildrop to slipslide its way down from the underside of a valvecover,
meander through various engine paths, all the way into the pan, during which time it's also cooling off?

How long does it take for a 248F-oildrop to slipslide its way down from under the pistons' wristpins,
down the rods, off the crank, (lil bit stays under the crank I hope), and drip into the pan as it cools off?
I wait 5min. Even that is a long time ...
About how long it takes to smoke a cigarette? (unless you're Keith Richards)
Dealership waits 15min when doing the “oil consumption” test.
About how long it takes to eat a meal?
I pumped gas ... in the early 70s ... at least 20% of the gas customers also asked you to check their oil ... we could not wait 5 minutes for the oil to settle to check the level ...
If they asked you to check WHILE pumping gas, under 5min?
If they asked AFTER, that'd depend on the size of the gastank, or how much gas they wanted?

Can't think of any more hairs to split. Not worth waiting more than however long it'd take for an engine to cool off in winter?

Well... I went ahead and tested this. Measured level a few minutes after I got home and then again a few hours later. It was about ¾ quart difference.

You saying it read 3/4 quart low on first check and then full on the check hours later?

Correct. If I remember correctly, the manual states that the low oil mark indicates the engine is one quart low. So my oil level right when I got home was a little above that mark.

I would be pulling the valve covers and checking the drain back channels on the heads. Hot oil taking 3/4 of an hour to drain back to full, is way too slow, again IMO.

Clearly, you never pumped gas for customers. 90+% ask you to check the oil BEFORE you you start pumping gas. And, you check the oil WHILE the tank is being filled with gas.

Required efficiency. Otherwise, other cars in the line (yes, there were lines) get pi**ed and start honking at you.

Absolutely right.

LOL, plus, depending on the driver, you want to hurry through that so you'll have more time to wash the windshield.

I pumped gas in '68 and '69 to make some extra money, in high school. First time I ever used an old tire machine too.

Anyway, it made sense to get the gas started before I checked the oil and did the windows. No one showed me that, it just made sense. An older guy worked there too and he said to me one day, "you've done this before". I told him no and he said I moved around a car/truck, like I had done this type work before. All I knew was what my dad showed me. It was a Sinclair gas station in Excelsior Springs, Mo. I actually had fun working there.
