Providing the necessary maintenance on your JK is important if you want your Jeep to continue to take you off road, or down the road, with ease.

Providing the necessary maintenance on your JK is important if you want your Jeep to continue to take you off road, or down the road, with ease. Fuel servicing is easily done, but it does require you to be organized so that you have a regularly scheduled plan for checking fluid levels and maintaining them within acceptable ranges. Neglecting fuel service maintenance can lead to long-term damage, especially if you continue to run your JK on low to non-existent fluid levels. To do the service maintenance yourself, all you need to know are the specs given for your year and trim of JK, as the ratings and specs can change from year to year. The following information can act as a convenient reference when you are ready to check fluid levels, filters, and capacities for your JK Wrangler.
