So I did my first oil change on my 2025 1500 Big Horn 4wd with the Hurricane tonight. I had to use oil filter pliers to get the filter off, but other than that it was easy. It was starting to rain, so I quickly dumped an 5 quart jug of Valvoline 0w20, and some random amount out of a second jug. I hopped in the truck, and ran it for about 90 seconds and turned it off. Then I reset the oil life monitor and checked the oil level. It said it was perfectly full, not over, not under exactly full like it said from the factory.
I took out the manual out followed the “Oil Level Display - How to Refresh” instructions on page 305 and it came back exactly half way between minimum and maximum. I drove it to my local auto parts store to dump my used oil, and repeated the refresh procedure (level ground, oil over 120F, engine off, but ignition in the “run” position for 4 minutes). Same reading. It isn’t impossible, but I find it highly unlikely that this gauge shows the actual oil level. I expect that the display will only report 4 or 5 settings that correspond to the lines on the gauge.
