I had a Grand Cherokee V8 before this Cherokee. This V6 Cherokee runs much lower RPMs on the highway than the V8 (4spd w/ OD) ever did.
What's interesting is at 70 mph my mpg is increasing and on my Grand (V8) it was decreasing. Something like 19 mpg (V8) vs 32+ on the V6 Cherokee. That's huge and likely a lot to do with the 9 speed.
The pay off will be there for us for sure. I just wish that Chrysler would put a wrap around on the visor or something to warn the customer of proper break in. I think it would save them a lot of grief. For some reason I think this Cherokee is susceptible to bad things if not broken in or stressed early on. I know differentials are very susceptible to damage with excessive heat and improper/damaged lube. I went through that with my 2001 Cherokee Sport w/off road pkg. The dealer used reg. axle lube instead of synthetic which was called for with the tow group. The only reason for that was heat produced when towing on those gears.
You have many, many good miles ahead for you with this great vehicle!
Wow, this thread feels like reliving the good old days again.
I think it was in the early 2000s that the automakers led us to believe that their vehicles would not require a proper break-in procedure. We all got spoiled, didn't we...
I am going to put those extra notes on the vehicle myself, before anyone from my Family attempts to drive it, to play it safe.
The sad reality is that the dealerships do NOT know the products they sell, at lest not well enough. The KL that I tested had less thank 50 miles on it. I was taking care of it for an hour-and-a-half gently, similarly to what the manual calls for. The guy that took it for a spin once I was done with mine, a totally opposite story. The sales people never said a word. At the the end someone bought that car...
Now, when you think about the benefits, it makes so much sense to make the extra break-in effort. I am hearing 30mpg when cruising 70(+) mph. That's typically the diesel's territory. This is it, just right there...
Thank you guys for all this great feedback!
