I'm just curious how many members run a full 6 quarts of oil in there 5.5 quart 111? (pre -3/2019) And if you do what are the positives and any negatives you have noted from running 6 quarts of oil in the 5.5 quart engine. I know what the manual says, I do change my own oil (5.5 quarts of Amsol, 2018 Chieftain) and I know how to check my oil level. I'm just genuinely curious, I mean there must be a reason that Indian switched to 6 quarts other than convenience right???
