I essentially agree with the preceding posts, but I want to add that–IMHO–you are wasting your money by putting expensive synthetic oil in a 9-10 year old car with over 100k miles on the odometer. When you consider that this car likely has only 2 or 3 more years of serviceable life left in it, any “dino” oil that meets Chrysler’s specifications will be sufficient.
If you want to go for the high mileage oil, that might help to slow the rate of consumption somewhat, but I would urge you to not spend too much money on the oil for this car. Just keep the oil level as close to “full” as possible and start saving your money for the next car.
