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.
My renegade has 24-25k miles. I got the basic warranty and noticed as of late during warmer weather it drains oil like a maniac. Should i be concerned?
