The current online 392 supplement says 7.5 quarts. I especially like the part about the oil filter when it says "We recommend you use Mopar Engine Oil Filter or equivalent" without listing a part number.
Thank you for that! I had written in my maintenance notes 7.5 qts, but couldn't determine where I'd seen it.
The online supplement is likely more current than my October production 392 which lists 7.0 qts. It looks like the 392 already has three different capacities listed - wonder if there are actually two different steel oil pans being used? I guess the next oil change will tell me the right answer for my VIN....
I was able to find a different online supplement that said 7.0 quarts. The one on the Mopar website right now says 7.5 quarts but it also says that driving in dry conditions in 4Hi Auto can cause damage.
