2022 First Oil Change

I have 1800 miles towing a 7k# trailer and a total 3,000 miles on this Hemi and did my first oil change today. The oil life indicator was at 65%.
I’ve read some of the other oil change threads and have to agree, the oil filter was very obnoxious to remove first time….. Especially when compared to my 4th Gen Hemi Ram. The oil pan drain bolt was only snug and required a small effort to loosen initially.
I did purchase a 14 Flute 74 mm cup to remove the filter, but it fits very poorly, actually loose. When I tried a 73 mm at the store it was too small and wouldn’t fit. It would seem that a 73.5 mm might be the correct size, but I have not seen one in this size.
I have several of these collapsing jaw oil filter removal tools with large hex nut on end that work great. Slide right onto the filter and used a short adjustable to turn nut. The filter took a solid 1.5 turns to loosen to where the tool was not needed.
I used the same method today that I’ve used for many years when removing oil filters in tight areas that are above steering and other components. This is a simple plastic cup that I trimmed a side opening on to get under the filter. I spin the filter and let it drain initially into the cup, and then spin it all the way off, letting it drop into the cup. The cup catches the majority of the oil that follows the filter removal. I removed the cup with filter from the back side, going between the front axle and rack and pinion steering.
I purchased a case of the factory MO-339 Mopar oil filters and 6qt Havoline 0w20 containers that meet the Mopar MS-6395 oil specification.
Going forward, my plan is to change oil and filter at 5,000 miles because many of the miles will be towing between changes.
