Engine RPM and fuel economy
Just got a 2025 Lonestar with the SO hurricane engine. I noticed that the RPMs exceeded 2000 when going over 70 and there was a dip in fuel economy to around 15 and 16 MPG. I recently had a loaner with the same engine and transmission but noticed lower RPMs and obviously better fuel economy...- rjanuszewski
