Current modifications to gain mpg:
Aluminim wheels in summer. I had tire pressure higher than door jam specifies. switch back to steel wheels with new ebay tires for winter in september 2024.
-Disable power steering pump. Shorter belt that avoids power steering pully
-Disable automatic and daytime running lights.
-paint roof white to reduce heat in cab. Then i dont need the windows down as much.
I also fixed exhaust leaks and replaced failing front o2 sensor
