One liter is equal to 1.1 quarts, so 6.5 liters would be 7.15 quarts.
It's hard to say without the year, model and engine size. From 1990 on, Cherokees, Comanches and Wagoneers took 4,5,or 6 quarts depending on which engine. the 2.5L engines take 4 quarts, the 5.2L engines take 5 quarts and the 4.0L engines take 6 quarts. I suspect but don't know for sure that the same engines would be in the Wranglers.
It may vary from one application to another. Most, I believe, take 5.
According to the 1999 Ford E-350 Owner Guide : With engine oil filter change : The 6.8 liter gasoline V10 engine takes ( 6.0 U.S. quarts of 5W-30 )

If you mentioned the name and model of the engine, you may get a better answer.
For a change with filter, add 4.5 Quarts (don't forget to fill the filter). Run engine for a few minutes, allow the oil to drain back into the pan for another few minutes and recheck. It may take an additional 1/2 quart, or may not. The distance of the cross hash marks on the dipstick are typically the equivalent of 1 qt.
