this vehicle when driving intown stop/go etc gets about 15mpg..
on the hwy at 70mph you should get 23-25mpg...
replace the air filter every 12-15,ooomi if paper type...more often in on off pavement driving...
get CRC MAF cleaner and give the sense wires a small spray ..these MAF sensing wires dirty will effect air mixture ...
at 100,ooomi replace the upsteam O2 sensors these also adjust fuel mixture....replace the PCV and inspect all these hoses for cracks splits poor fit ALL...
Use synthetic engine oil 5-30wt ..
keep tires inflated to 35 PSI..
