Grand Cherokee 5.9 Advice
Hi All,
Just looking for input on what you think of the 5.9 Grand Cherokee from
1998 as a reliable vehicle. I have a 1993 with the 4.0 inline 6 that has
been great for over 265,000 miles. Is the V-8 as reliable? I know this V-8
was a special order type thing and is a real fire-breather. Reason I ask is
I have seen one for sale in town and it's very nice looking. Not sure what
they're asking for it though.
Thanks.

Yes it was the firebreather for 1998, but now it is in the lower-middle of
the road v8 range for 2006.
The non-HO 4.7 has 230 hp, the HO 4.7 has 265 hp, and the 5.7 Hemi's got
325 hp.
The 5.9 also requires 91 octane gas. And it is a pretty thirsty engine
on top of that--13 city, 16 freeway (mpg). That's with a compression
ratio of "just" 8.7 to 1.
The 5.7 Hemi is recommended to use 89 and the compression ratio is higher
at 9.6 to 1.
As a sanity check, the 4.7 non-HO "must" take 87 octane and it's
compression ratio is 9.5 to 1. Heck, the manual says it will run
rough if you put better grades in it... (This I have NO idea why...)
The current hot-rod topend engine is the 6.1 Hemi and while it also has to
use 91, it's compression ratio is supposed to be 10-something to 1. And it
is supposed to have 415-425 hp... (!!!)
