Looking for oil change recommendations for your 1985 Jeep J20? Get the advice you need at Firestone Complete Auto Care! We are experts in car care — not just tires. We know the ins and outs of motor oil, too. We couldn’t put it better than our technician, Brianna. She likes to explain to customers that, “Oil is the blood of the engine. It’s the #1 thing you can do for your car.”
Jeep recommends changing your 1985 J20’s oil at regular intervals. See mileage and month specifics in the above table. Your J20 may need an oil change right away if your check engine/oil change light is on, you hear knock knock knock coming from the engine, sense an oil smell in the cabin, or see an excess amount of vehicle exhaust. You may also need an oil change more frequently than Jeep recommends if you haul heavy loads, drive in dusty terrain, enjoy off-roading, or go at low speeds on long distance trips. More frequent oil changes generally won't harm your Jeep J20. Each oil change is actually another chance to check and resolve other car issues, such as worn brake pads or tire treads.
Your local Firestone Complete Auto Care has the right 1985 Jeep J20 motor oil: either synthetic or conventional. Jeep has specifically identified either synthetic or conventional as the best oil for 1985 Jeep J20 vehicles. Motor oil helps lubricate the engine’s moving parts, maintain proper engine temperature, and prevent the build-up of harmful substances within the engine. During an oil change, a technician will change your J20's oil, replace and recycle your used oil and filter, check all of your other filters, top-off important fluids, and visually inspect the rest of the vehicle. You can drive with confidence knowing that we look out for you and your J20 by taking into account your driving style, weather and road conditions,
Wondering if we carry the right motor oil for your Jeep? We stock outstanding motor oils because that's what your engine deserves. Check your owner's manual and talk with a technician to select the right Jeep J20 oil, whether it's Quaker State® Advanced Durability™ conventional oil, Pennzoil® High Mileage Vehicle® motor oil, Pennzoil Platinum® Full Synthetic motor oil with PurePlus™ Technology, or Shell Rotella® heavy-duty engine oil. With so many motor oil brands in the market, why do we carry these brands? They are champions. For example, when tested in taxi fleets across North America, Quaker State was shown to provide 2x more protection than the industry standard.  Pennzoil is another option. Unlike traditional synthetic motor oils, the Pennzoil Platinum® Full Synthetic line of motor oils with PurePlus® Technology is formulated from pure natural gas, which helps lead to better performance. But don't forget about Shell Rotella for heavy-duty engines. It's specifically designed for diesel and gasoline engines that need to withstand rugged conditions, and is uniquely strengthened to deliver improved oxidation resistance, heightened performance in extreme temperatures, and increased wear protection. Always refer to Jeep's recommendations before going with a new or different motor oil for your 1985 Jeep J20.

 ILSAC GF-5 represents the latest performance standard set by the International Lubricant Standardization and Approval Committee (ILSAC), a joint effort of U.S. and Japanese automobile manufacturers. Most automobile manufacturers are expected to recommend oils that meet ILSAC GF-5. API SN is the most recent service category issued by API’s Lubricants Group. Oils meeting API SN and the new “Resource Conserving” designation meet all ILSAC GF-5 performance requirements.
