I have an '18 Trailhawk with the 2.4. Just hit 10k so I was set for my second oil change. Going around a turn one night last week, I got the Low Oil Pressure notification that quickly went away once I straightened out. Upon checking the oil, the stick was barely reading anything. I was 3 quarts low.

I just got back from dropping it off at the dealer for an oil change and I mentioned the low oil and he told me "off the record" (of course) that the 2.4L Tigershark engine used in the Renegade and the Compass is made of a soft aluminum that is very porous. There isn't an oil leak and the engine isn't burning oil, rather the engine is 'absorbing' the oil. The oil consumption will trail off around 15k miles.

I'm not a mechanic, but I've also never reached for a soft aluminum sponge to clean up any spills around the house. So this is either insight, or comedic relief. I'll be keeping an eye on my levels from now on.

The issue with oil consumption has been spoken of, and documented since 2014 when the first Renegades were delivered to customers. It is a fact that these engines drink an amount of oil. The oil is very thin in newer cars, and some engines tend to use oil because of that. My theory is that once one of these engines gets a quart or more low, the oil gets hotter and thinner, making the issue even more prominent. That is to say that that the lower the oil, the faster it goes away. I'm hesitant on saying that it's being burned because there would be an equal amount of catalytic converter complaints/replacements, and that's not happening. That being said, I don't know where the oil is going, since there are very few complaints of oil leaks.

I have a bridge to sell you.

Yes, metal/aluminum will absorb a SMALL amount of oil due to it's purosity. To absorb quarts of oil is insane, the engine block would be double it's size with 3 quarts.

I only have about 4K miles on my 17 Altitude but it has not consumed any oil so far.

I hate to be one of those "I don't have that problem." people, but I feel it worth mentioning (for the benefit of my resale value if for no other reason) that this is not a problem with all of these engines. My 2015 TH has 23K miles and has never needed oil added between changes. Because I read this forum daily, I check my oil (and radiator fan) often and have never seen the level move.

For what it's worth, I almost always check my oil level when the engine is stone cold. The only time I check it warm (per the instructions) is right after I change it. And honestly - I've seen virtually no difference of the level on my dipstick whichever method I use. When I change the oil, I get it close to full then warm it up and top it off to the top of the hash marks. I just checked it this morning after sitting for a couple of days (as I started this reply), and the level is right at the top of the hash marks. It's been months and a couple thousand miles since my last oil change.

BTW, I still carry a quart of oil in back (along side my matching spare tire).

I checked out the link and I'm glad that costco sells top tier gas. Thanks.

i raced fords for 30 years, did all my own work, and i have never heard so much BS on this oil problem, flimsy piston rings, oil absorbing engine blocks, bad valve guides. damn jeeps have to be "burning" oil, BUT i hear of no "cat" problems or exhaust smoke. i think 0-20 oil is way to thin for these engines and burns off to cleanly. has anyone tried a 10-30 blend, dumb question because that would have been mentioned on this site by now if it made a difference

As far as I know, I don't think anyone has done so, but I do agree that maybe the 0w-20 oil may be too thin. I have also heard that this engine is designed for the thin oil and that thicker oil may cause problems. I am not convinced. I'll check the manual to see if it specs for thicker oil in warmer climates.

My oil on my 2015 Jeep Renegade Latitude burns extremely fast using the Mobile 1 0W-20 Fully Synthetic. At one point I even was using the Mobile 1 OW-20 Fully Synthetic Extended Performance just to see if it would make any difference but did not. I have to ensure I change this vehicles oil every 3k otherwise when I check the dipstick, it will be a half/quart less within the 3k range. Would anyone recommend a different brand oil than Mobil 1 that may last better with the Renegade? Thanks.
