Re: Is changing rear ratios worth it?
This doesn't answer your question, but I thought it would be appropriate to share. With my original 4.56 I was getting 9 mpg (mostly highway). After switching to 3.54 it improved to 11.3 mpg (same highway driving). The only reason I made the gear swap was due to the amount of highway driving I do and didn't want to beat the engine up keeping up with traffic.
