I was looking at getting a newer used Ford Ranger 4.0L or Mazda B4000
extended cab 2 wheel drive truck. I have read that the gas mileage is
almost the exact same with the 3.0L and the 4.0L so might as well go with
the bigger one - right?
Here is the question. I read that the compression on the 4.0L is 9.7:1 -
This is really high yet they say it can run on regular fuel. What do you
guys find? Are your engines pinging on regular. What is everyone using for
gas in these? Comments......
