I am wondering what kind of mpg you guys see on your wagons out on the road. mine is an 87 w/ only 109k and new plugs,wires,cap,rotor,coil... it is very smooth oout on the highway. Quick and good downshifts etc. most of the time I am out of the boost...
but I just took a highway trip Friday- Richmond to Washington- in medium to heavy traffic...Meant that my cruise was mostly about 75 mph but required some burst speeds up to 85+ occasionaly to get around highway left lane bandits creating big clogs.
Anyway I got 17mpg going up and 19mpg coming back . This seems low to me, most of the time I was not into the boost at all...so I wondering if this also may indicate the O2 is rich sense everything else in the ignition system is new.
Bosch suggests a new O2 can give a 10-15% improvement in mileage.
Also was not carrying more than 100lb load going up...just me coming back and closer to 80mph most of the time on the return trip.
Thanks
