Depends on driving conditions and the quality of oil used. I would feel comfortable running a conventional oil up to 5k miles under normal conditions. I would feel comfortable running a high quality, group 4 oil up to ten thousand miles.How often should the oil be changed on a 2018 JLU 3.6l? The dealer suggests changing the oil every 3,000 miles....which pretty frequent.
Any idea what factors the oil life monitor uses to determine life? Is it purely mileage?The Pentastar that went 625k miles ran 8k oil change intervals on Valvoline 5w20. I was going to go with 5k intervals, but IĀ“m leaning toward just using the oil life monitor, which winds up at 7k to 7500, with my driving style. IĀ“m running Rotella Gas Truck 0w20 right now, but will be going back to Mobil 1 AP on the next change.
I havenĀ“t seen a 0w20 yet that wasnĀ“t at least a synthetic blend, and that one was Pennzoil Gold. I think it is a great oil and has stats that are right there with Platinum, so i think 3k is just too frequent, unless you drive in a dusty desert.
Of course the dealer would recommend you do their $120 oil change as often as they can convince you to.How often should the oil be changed on a 2018 JLU 3.6l? The dealer suggests changing the oil every 3,000 miles....which pretty frequent.
No, it is much smarter than that.Any idea what factors the oil life monitor uses to determine life? Is it purely mileage?
Coming from the Tacoma (10K intervals) I asked my dealer and they said trust the computer or do 5K if you don't trust the computer. I just want to know what the computer considers.The manual (mines a 2019) seems to say wait for the Jeep to tell you it wants an oil change but donāt go more than 10,000 miles without one. 4,000 miles if youāre a āsevere dutyā user. So in any case, and once again, a dealer is full of...misinformation.
Same here. Likewise, since it's recommended to rotate your tires every 5k as well, I do them both at the same time. It's a simple method of maintenance that doesn't require window stickers in the corner or wondering the exact mileage of your last service.I change mine every 5,000 miles with full synthetic. I consider my Jeep get severe service with off road use, travel trailer towing, etc. I've seen oil temp over 240 at times.
For me it's peace of mind. These things only hold 5 qts of oil. It's easy to change and not that expensive.
Talking to Kevin on Bitog, who was on the Pentastar design team, it uses many data points. He said it is a very complex algorythm and you can trust it 100%. That said, with that complex algorythm and all, it lands about squarely on 7500 miles for me, give or take a couple of hundred. But my driving profile over the course of an oil change interval may be very consistent. IĀ“ll go back and review my conversations with him and see what he said specifically. I remember hours, total engine revolutions, time, as in calendar, and start-up cycles were all part of it. But I think there was more than that. IĀ“ll note that I rarely do short trips. My commute is 17 miles and 35 minutes, so the engine gets fully up to temp and burns off any moisture or fuel in the oil, every time. IĀ“m sure a short trip profile where the engine rarely gets up to full temp would trigger a shorter run on the oil life monitor. A mostly highway profile would probably trigger a longer one.Any idea what factors the oil life monitor uses to determine life? Is it purely mileage?
Cost me very little to do the oil change this morning > $3.98 for the on sale last year, Mobil 1 M1C-456A Extended Performance Cartridge Oil Filter and then a 5 qt. container of Pennzoil Platinum Full Synthetic Oil at a cost of $12.00 after rebate. 15 min. labor.I change mine every 5,000 miles with full synthetic.
