Long idle time

[BRDN]

2013 5.7 hemi, 180,000 miles. I change my oil every 1500-2500 miles now depending on when the lifter noise starts. I idle, a lot. During the hot NW FLORIDA summer 95% humidity I nap for about an hour in my A/C Ram about 3 times a week. I use a stick placed under the seat and pushed against the accelerator pedal. I will usually idle at 1200 rpm’s. This is based off of my Cummins days. My question is…”Is 1200 rpm’s enough for lifter lubrication for long napping idles?

1200 would be perfectly fine to ensure lubrication. Even 900-1000.
