What can I do to get better mileage performance in a 1999 Dodge 1500 Ram? Also, the dash is cracked in several places, any recommendations on how to fix it?
Someone suggested putting a type of fuel booster of some type and then changing the
spark plugs. I would like to get better mileage performance. Should I be driving in 4L or
2L? I have been driving it in 4L and the 4wheel drive light is on.
