If you have the room and finances seven 5qt. containers will yield five 7qt. oil changes , no need to buy 1qt. containers.

Lotta Bucks on oil, depending what U R getting. I get a 5 qt jug PUP 5 W20 from Walmart for $28 plus shipping. No place around here sells the Ultra, gotta order. Tho Walmart price not bad. NAPA wants $42 to order same thing.If you have the room and finances seven 5qt. containers will yield five 7qt. oil changes , no need to buy 1qt. containers.
A 3.0 takes 7.5 quarts of oil??@GeauxinUp
Makes sense to me. (sic)
They actually take 7 1/2 quarts of oil with filter change. Just looked it up in 2025 Ram Manual.
ALSO: per RAM:
Synthetic Engine Oils
Your engine was designed for synthetic engine oils, only
use synthetic API approved engine oils.
Synthetic engine oils which do not have both the correct
API trademark and the correct SAE viscosity grade
numbers should not be used.
@Islander39erA 3.0 takes 7.5 quarts of oil??![]()

Wow. That's a lot of oil for the displacement.@Islander39er
YUP, the Inline Hurricane 6 takes 7 1/2 qts. See below out of 2025 manual: Remember, 3.0 in this case Inline Hurricane, not the ED baby Diesel.

For sure, 2.5 quarts per liter is on the high end. You regularly see 2 quarts per liter in smaller four cylinder engines. The Toyota 1.8 liter engine in my old ‘82 Corolla used 2.2 quarts per liter. I see that as a positive thing. I don’t know for sure if it will help your oil remain in grade longer but it seems like it should in my own head lol.Wow. That's a lot of oil for the displacement.
I'm sure someone has the science to confirm or deny it.For sure, 2.5 quarts per liter is on the high end. You regularly see 2 quarts per liter in smaller four cylinder engines.

And that friggin ED takes a specific oil with specific additives also. I had an ED, how I know, but my ED was a 2015, Gen II, took the Low ash 5 W30 oil, and that friggin oil was Expensive.I googled it out of curiosity, and found out a 4th gen ecodiesel takes exactly 10 liters of oil. That's convenient in one way (for those of us in metric jurisdictions, anyway). Two 5 liter jugs, no leftovers, no small bottles.
Oh, I didn't know that. Good info for anyone considering one.And that friggin ED takes a specific oil with specific additives also. I had an ED, how I know, but my ED was a 2015, Hen II, took the Low ash 5 W30 oil, and that friggin oil was Expensive.
