I keep my tires between 38 and 40 psi. I find I get the best wear that way, not just mileage. Get you oil changed with Synthetic 0W20 next time. Changing the way you drive is part of owning a hybrid. Efficiently charging the IMA batt. and getting the best mileage practical will take a little time to learn. I guarantee this new civic of yours is not only better for the environment, but it's better in every respect than your older civic.
