2018 Jeep Cherokee with the 2.4 L with about 130 K on the clock. Which holds 6 quarts I was lazy to go to Wally and all I had on hand was 5 quarts of 0W20 Castrol edge black bottle and 1 quart quaker State ultimate protection 0w20 too completed my 6 quarts. Is it really that bad to mix different brands? I know someone’s going to ask what kind of filter it was a Fram orange can ph10060 😔

It’ll be fine.

6 quarts? Every 2.4l Multiair I’ve seen calls for 5.5 quarts.

The one in our Chrysler is right at the full mark with 5.5 quarts.
 
Oh no... not the group 2 and 3 oil mixed with another group 2 and 3 oil!

Lets say you wanted to use Quaker State only and so you put in 6 quarts. You'd still be mixing since there's a quart or so hidden in the engine that doesn't drain. You're always mixing oil.

If we want to get technical there's a 99.999% chance there's still factory fill in my 343k yukon though it'd only be less than a milliliter at point since i've never torn it down and sterilized the inside of oil with solvent. But whatever i'd put in after that would remain until the last molecule is gone long after.

With 5.5 it’s only halfway up the dipstick on a level surface

Interesting.

Our Chrysler and a 2018 Jeep Compass that I service are right at, or just a hair below the full line with 5.5 quarts. I even drain them until the oil’s barely dripping.

Oh well, I don’t blame you, I’d top it up to the full mark as well. I have to do that with our Mazda using the 4.8 quarts it calls for. It always takes a little over 5 quarts.

You’re right about the Mazda. My neighbor has the same problem. He puts around 5 1/4 or 5 1/2 quarts. He was telling me. Maybe my dipstick is longer than yours on my jeep. 😂😂
 
can't find the VOA anymore, but many moons ago I made a Frankenbrew with the left over .5 qts from 9 oil changes between the cars my buddy and I were driving at the time ( both took 4.5 qts) half were 5w30, half were 5w20, there were no notes from blackstone about anything to worry about, and unsurprisingly, they said the Viscosity tested as a "heavy" 5w20...

Approx .5 qt ea. of:
Nextgen Maxlife 5w20
Pennzoil Conventional 5w30
Formula Shell 5w30
Pennzoil Conventional 5w20
Mobil Super 5000 5w30
Eco-Power Synblend 5w20
Meijer 5w30
Formula Shell 5w20
Nextgen Conv. 5w30
Mobil Super 5000 5w20
