There are three engine options for the 2015 Jeep Grand Cherokee. Here are the types of oil you’ll need for each:
Regardless of which oil is needed, Jeep recommends using fully synthetic oil for optimal performance. Conventional and semi-synthetic oils are viable alternatives, but not ideal. Jeep recommends doing an oil change every 10,000 miles or every 12 months, whichever occurs first.
If you’re not sure which engine your Grand Cherokee has, it’s best to double-check your owner’s manual.
