Yeah, but what oil should I run for best fuel economy if I run shinko tires?
Jk.
Aforementioned 52mpg of the XB is just with a K&N filter, hawk pipe, and tune. That's running 70-85 too.
With my 1125CR I'm lucky to see 40mpg on the highway, usually high 30's. diddling around town, mileage is garbage.
