Personally I would not consider either one. You can buy oils that meet much more stringent approvals for cheaper. I think PUP is mostly marketing. It just has API approval. I would look at a Amsoil personally if I owned a Jeep. Not my first choice for a vehicle, but if you're comfortable eating the crazy Jeep depreciation, the low MPG, paying for all the stuff that will break on it, and the tires, then I wouldn't pinch pennies on the oil, and just use Amsoil. If not, then I would use M1 ESP 0W-30 or Quaker State Euro 5W-40 which is $23 at Walmart (without a sale).
