I have really have had no problem running 87 octane in my 2016 Ram 2500 with 6.4 hemi and 4.10 rear. I generally run 87 when not towing. When towing my 12K fifth wheel I try to use 89 octane when available. At least one time I can remember no 89 octane was available and I needed gas when towing. I filled with 87 octane and continued towing the fifth wheel. The manual does say 89 recommended and 87 acceptable. I have found no real difference in either performance or mileage. Hope this helps.
