Well, when I drove teh 93 Cherokee off the lot it required a break in
period, but no special break in oils. They recommend keeping itunder I
think it was 45 for 500 miles and under 55 or 65 I think for the next
500. Unfortuantely the car wast totaled by a nice man who hit me in the
side right at the crash cage. the tab of repair work was almost the
prive pof the car... new!
