Hi everyone! I'm from Tamaulipas, México. I have a Jeep Comanche 1988 with 2.5, 4 cylinder motor. I drive to my work every monday 68km , but the gas consumption I think that is to high for a 4 cylinder motor, I spend 10 liters of gasoline. The highway were I drive is a big Montain. This is my first Jeep in my life and I love it, but I need and opinion of you guys, if this consumption is normal for this motor. Thanks, and I hope to get an answer. Regards.
