I drove 275 miles on a full tank on my last tank. This time I filled up and reset my mile gauge to track it again because I thought I was crazy. The car usually gets 350 miles+ a tank. I have burned through a third of my tank approximately 4 lines on the gauge and have only driven about 75 miles. I filled up the air in my tires, which are low profile but not affecting gas mileage in the past, and it is still horrible. I recently put a new air filter in, before the decrease in gas mileage, and am planning to change my oil tomorrow. I don't drive hard and do not see leaks nor smell gas. Is there a reason why I am losing gas mileage so quickly?
Look forward to any replies that could help me salvage my gas money. Thank you!
