I just got home and filled the CR-V again while I was out. The vehicle said 21.3 MPG for the last tank and the actual was 21.22 MPG
Have not tried it . Will use Top Tier VALERO 88 w/E5 on occasion . It's usually Top Tier VALERO 90 w/o E .That's good mileage. Did you try to see if there is a difference in mileage between regular and premium/super?
