My truck does not have an overhead console. I check my mileage via the odometer at every fill-up. I also fill my truck up all the way to the top of the fuel tank neck every time I fill it up. I can touch the fuel when I put the cap back on. Tabs are not broken. Just checked those recently. Tomorrow I will check for a turbo leak at the firewall. Also gonna look into the DIY Tymar filter.
Thanks!
