I recently had my front struts replaced under warranty by Honda. Right after the replacement, I lost 4-5 MPG or 1.5L/100km per tank. I have been driving the car for 3 years and have always had consistent fuel efficiency in which I keep track. So the difference is directly related to the replacement. However, I cannot figure out why and brought it back to Honda and they deny that it has anything to do with fuel efficiency. This is driving me crazy as I bought the car originally to have good fuel efficiency.
Any ideas??? Thanks in advance!
