i have a 2008 subaru tribeca and in an effort to increase mileage (19.1 mpg) i put in archoil 9100
it has been about 1000 miles and fuel mileage is now 19.3 mpg
this is not scientific
driving conditions have remained the same
engine seems smoother but that does not mean much
not sure if i would buy it again
just my thoughts
