I recently installed a glass mat battery as opposed to the regular Honda battery, my gas mileage tanked. And I don't mean just a little I lost 5 to 8 miles a gallon depending upon weather and whether or not they're putting the winter additive in. Does anybody know if the lower charging voltage, and the higher output voltage affects the computer in some way. I don't have any lights for the alternator on my dash right now or at any time in the past, but I'm going to have to check it just to be sure over at the shop. It just seems weird I changed the battery and I get lower gas mileage. Not making this up real story.
