Reading the 2025 RAM 1500 owners manual... It says 3.0L HO needs 91+ gas, while 3.0L SO is OK with 87. But there is this remark:
"The use of 91 or higher octane premium gasoline will allow these engines to operate to optimal performance. This increase in performance is most noticeable in hot weather or under heavy load conditions such as while towing."
My gut feeling is that 3.0L SO on 87 will perform worse than 5.7L on 87. If I need to put 91 gas to get advertised power, it makes no finance sense comparing to HEMI.
