Your Jeep has a computer that would tell and find out what octane it needs to pull the loaded weight; if you use the cheapest low octane gasoline, your engine would need the octane needed to make the combustion explosion and make the cylinders move up and down. Manufacturers place the minimum octane needed for the combustion explosion to occur, but if you use the best or higher octane gasoline, your computer is smart enough to tell how much it needs for its necessary combustion explosion to occur. Higher octane gasoline has much more advantages for your engine, it's more powerful, has injector cleaners and other engine soothing combustion and in other words, please don't think that by using a cheaper gasoline you're saving money, it's wrong!. Your car computer will know how much of the fluid is needed to compensate for the octane needed in the engine explosion, I'd always use super or premium gas and in the long run I'm saving money and have more power in my car. If you're trailer car pulling on regular gasoline your jeep will spend a big amount of the fluid to do the necessary work and you'll be refueling more often.
