Just regular maintenance and enjoy the mpg
I’m still between 44.2 and 46 on average since I switched to Chevron gas with them attached. Without the crossbars and on a lower grade gas I was around 41/42mpg, I’m still using 87 octane just seem to have better mpg with Chevro. I suppose I could remove my crossbars and check what my mpg would be becau it shouldn’t go up after installing them.Beautiful!
I bought used cross bars too for the CT but haven't had time to try them on lol.
I quit camping though so probably won't be needing to attach it.
I think fuel economy takes a slight hit with those installed.
