Quick heads-up for '22 and newer Ram ProMaster owners, the Pentastar engine's oil takes longer to drain back into the pan during an oil change but since no official wait time is given, make sure to give it extra time before checking the level for an accurate reading
 
here's a quick pro tip for your oil changes: the Pentastar engine's oil takes its sweet time draining back into the pan. There's no official wait time, but give it extra time before checking the dipstick. You want an accurate reading, so be patient!
Nice tip! yeah, waiting a bit longer before checking the dipstick makes a big difference for accuracy

I so agree with you! one more tip: always replace the drain plug crush washer (gasket) every single time you change the oil.
why? bcs it's designed to deform and create a perfect seal for one time only
Reusing an old one will increase your chances of a slow, annoying drip or, worse, a full on leak
It's cheap insurance against a messy driveway or low oil levels

I was a heavy line mechanic for years at dealerships and my own shop & continue to change my own oil even though it's harder to do now.
Started using a oil recovery pump with hose down the lipstick tube. I heard the PM oil pan drain is.a.bit higher than the bottom of the pan
( like a lot of vehicles) and this method gets all the oil out on the bottom plus it's quick with no mess!
Everything is completed top side and I have it drain right into my used oil container. Since it's so easy and cheaper to do yourself, I change my oil more often than most.
Works for me.
 
a friend of mine did that mistake and topped it off all the time, untill he blew the engine and one replacement later he practically waits for a week :)

Not sure why it takes so long, but it's something that many owners don't know about

Quick question, what kind of pump are you using? And does it work well even if the oil's cold, or do you warm up the engine first? Curious how much oil you're actually able to pull out compared to a full drain.
 
I always let it warm up to help the oil flow better when hot. Picked up a cheap 12V model off Amazon for about $25 and it seems to work well. No more crawling under it and/or jacking it up. Promasters only (Kips website) showed the drain being slightly above the drain hole but it shouldn't be too much left.
Maybe 1/4 quart but the ease of removing it is what I like the best.
