Alright this is strange. Until two days ago, I only got about 190 miles/tank. That is at 190 miles, the gauge said empty. So, I fill up my tank (two days ago), and go to work. I drive all over my area. I've gone 50 miles, and the needle hasn't budged much from the Full marker. Somehow I end up driving 180 miles and it says its half empty. Just to be safe, I go to Exxon to fill 'er up, I was only able to fill it up 7 gallons. I'm like, "What the hell is this?" I never had this kinda mileage before! So, now my car gets good mileage. Or maybe the guage was f'ed up before two days ago. Now I'm happy.
