2001 Jeep Grand Cherokee need advice
 

I just bought this car and need to know what octane rating fuel I
should put in it and a few other things that he manual would tell me.
No manual came with the car. Should I get a manual from Jeep or an
after market book?

Any guidance appreciated.

Re: 2001 Jeep Grand Cherokee need advice
 

The 6 cylinder engine uses 87 octane regular.

There are two V-8 engines. The 4.7 liter Power Tech engine uses 87 octane
regular. The 4.7 liter HO engine uses 91 octane premium.

The HO engine will say so on the intake resonator..

Engine and altitude set what you need for octane. Start with the
mid rating and stay away from E89 (ethanol) fuels. (not certain
exactly when Jeep made the system ethanol compatible but for older
systems it eats the plumbing)

The Jeep service book is the best one to get. But it's also the
most expensive. However, if you do any work yourself the book
will pay itself back in the first job or two.

There might be a sticker inside the fuel door. If this is the I-6, I'd
recommend midgrade. I can only run standard regular reliably if at high
altitude and even that isn't so common since they upped the alcohol
content.

Head for www.jeep.com and select the For Owners link. From there you
can find links to get an owners manual and a strongly recommended
factory service manual--even if you never do your own work. You can
also open a service request where you can request a build sheet by
giving your VIN number... you get a list of everything the vehicle had
as it left the factory. Most dealers will also print you that same
build sheet and some will also order the manuals for you.
