I recently had my shock/struts replaced at @70K. Something I noticed besides the improved ride and handling: My MPG seems to be up? I have a 2012 Eco with now 82K on the clock and even while using 89 octane fuel instead of 93 it seems to be improved by a few MPG. I only mention this because I also replaced my son's shock/struts on his 2005 Chevy Classic and his car is exhibiting the same behavior. His MPG is up a few MPG also. I know this because I put gas in both cars and track via Fuelly. Does this change create less engine resistance or otherwise. I thought I read someone else experienced the same but I never researched and thought it an interesting observation.
