I'm sure this topic has been brought up many times. I live where there are many big hills that are about 15-28 degree inclined and but I'm trying to get better acceleration and hill climbing out of my 2.3L 4 cylinder ranger. I try to gain speed on these big hills. If the speed limit is 50 mph, I'll speed up to 60 mph to make the hill and by the top of the hill I've slowed down to 45-50 mph. Is that normal? I take very good care of my truck with regular oil changes and air filters, my tires aren't low, my brakes aren't stuck, but I do have an aluminum tool box in the back but it's not full of unnessesary things either and I need tools for work. Is there anything I can do to help?
