What oil to use in 4.0 97 Cherokee

Hi guys,

Bought the Cherokee 2nd(3rd, 4th) hand and there are no manuals with it. Its a 97 4.0L Limited Edition version.

So what type of oil should i put into it? Is there anything else i should do for maintance? Put 4000km on it since i got it and dont know what the last owner did maintance-wise.


I can get a smell of petrol of it occaisonally. Usally on really hot days i think. In Queensland, Australia.

Many Thanks for the tips guys.

10w30 is the manufacturer recommended weight. It will take 6 US quarts with a filter. I would also look at replacing spark plugs, wires, cap, and rotor just as general maintenance.

I'm not sure about the smell. You might start looking around for a leaky fuel line, or perhaps even a bad gas cap. Again, I'm not too sure about that one...

Most of the time 10w-30 is what is recommended. 6qtrs of it. Check the transfer case level and the trans fluid level.

Flush the cooling system and refill it with fresh coolant.

Check the serpentine belt condition and look at the motor mounts and trans mount.

Drive it and look for wet spots on the tank or smell around to try to find the source of the smell. Check the injector seats and look for wetness there.

If you have no history of maintenance, change out ALL fluids. Oil, transmission fluid, transfer case, both differentials, coolant (replace with factory 195 OEM thermostat while you're doing this). Fluids are the best investment on future reliability of your XJ.

For tuneup hardware, you'd be looking at replacing spark plugs, plug wires, distributor cap, rotor, air filter, check belt condition.
