2014 Jeep Grand Cherokee Limited with a piece of crap 3.6 l motor in it. Our car just turned 71,000 miles and had to replace lifters, rockers and oil tube! The oil was thick also and yes we changed the oil every time as needed. The mechanic told us to get ride of it this is the worst they made and our warranty expired last year. User's recommendation: Don’t by the 3.6.
