I was just giving all the details to show the really clean exhaust pipe wasn't due to anything wrong. I drive like a egg is under gas pedal most of the time. No loss of engine fluids. Use Motorcraft oil and filter, and oil stays clean and oil level never drops in 5000 mi. Use Cenex 87 E10 fuel. This is first vehicle where exhaust stays that clean. Truck is all stock except do have a Preloaded SCT 87 Tune.
