Hi Krista. If I owned a RAV4
Hi Krista. If I owned a RAV4 Hybrid that was getting less than 30 MPG in any scenario I would return to the dealer. This based on my testing. One option if you think it is the route, is to simply fill up the tank and zero the trip odometer. Then take the car for a ride on the highway or take a trip someplace. Then fill the tank again, note the miles traveled and gallons used and divide to get your mileage. See what the result is. When you fill up, be sure to stop the gasoline nozzle as soon as the tank is full and the nozzle clicks off. Don't "Top off." Let us know if you see any difference. I forget off hand how to zero the mileage counter on the RAV4, but it would be good to check that correlates to the MPG you get by doing the math yourself.
