Interesting information, and I'd say it's in line with most of the vehicles I have had over 40 years of driving. The majority of the have used about a qt between changes (3-4k miles).
We had a Toyota (89 Corolla GTS) that used none, an 88 Camry that smoked on cold starts (valve seals) and a 98 Subaru that leaked like crazy (way more that evev the 4.0 in my 98ZJ) till we had all the leaks fixed when we had the head gaskets done.

JeepCares, this is all good "guideline" info., and keep up the good work posting this type info. IMO, excessive oil consumption, in many cases (in addition to your service bulletin) can be traced back to the initial break-in of the engine. If it's driven like "granny" during the break-in period, you're more likely to have an increase in oil consumption later on. Today's engine assembly tolerances are much tighter than in the "old days", but a good varied RPM break-in will still, in most cases, result in less oil consumption over the long run. I bought my Hemi Magnum new and broke it in as indicated above and it doesn't burn a drop between 6000 mile changes. I don't know how my Hemi WK was broken in, but it uses a little (maybe 1/2 qt) between 6000 mile changes.I do get some through the PCV Valves and into the catch cans in both though, but it is minimal. I'll be doing an experiment soon, by adding a second in-line PCV valve to see if it will, (1) work properly and (2) reduce valve oil bypass. This will be an effort to correct the lousy stock PCV system in the Hemi's.

This specification certainly doesn't make me happy, but thanks to Costco, I have six quarts of Mobile 1 out in the garage for $26 (total) to insure I have oil to top off when some gets used. I did need to top off with a quart in the first 4K miles, but haven't used any perceptibly since my 8K oil just over 12K right now.

My 5.7L WK2 used almost 2 qts over 6,000 miles and it only has 7200 miles on the odometer. I guess it seems high given the extremely low to non-existent consumption with my other vehicles. No one else things that 1 qt over 750 miles sounds incredibly high? With the recommended 8,000 mile oil change, that could be as much as 17 qts per oil change interval!
Down 1 quart every 750 miles? That sure sounds high to me. I wouldn't be too pleased with that.
I've experienced very little (or none at all) oil consumption in any of my vehicles over the years. This is a relevant topic for me because I did notice I was down a quart in my 2013 V6 WK2 at 1000 miles, which surprised me. Checked for leaks & couldn't find any. I'm at about 1800 now & so far it doesn't need to be topped off again. But I'll certainly be keeping a close eye on it.

Found a table spoon of oil under my 2013 Patriot (2.4L 16,000 miles) yesterday. Jeep is currently sitting at the dealership awaiting an oil leak test. I had no idea that loosing 25% of your oil capacity every 2k miles would be acceptable. I have a 1998 Saturn that doesn't burn a quart every 3K.

Dealership found i was leaking from the oil pan. They dropped it, replaced the gasket and was on my way. Still no fix for the squeak when I back up. But I was very happy they fixed my oil leak.

Glad to hear your oil leak issue has been resolved! If you’d like me to look into the noise you’re experiencing when backing up, please message me your VIN.
