Because the KJ is a compactly constructed model, keeping the fuel service systems running optimally will directly translate into performance. Forget, or put off, regular maintenance and you may find that your ride doesn’t take the hills like it used to, your fuel costs go up, and systems start to go out on you. Taking the time to check levels on the transmission fluids, to make sure the filter is clean, and keeping the right oil in the engine can go a long way to making your Jeep driving experience a long lasting one. Use the chart below to determine which weight of oil, type of filter, and grade of transmission fluid is required for your year KJ.
