28 gallons of oil to go 50,000 miles seems pretty good to me, 1785 miles per gallon for your tires.
I think if you want to make a larger impact getting low rolling resistance tires is going to off set the oil used to make the tires more then the increased rolling resistance of a sub par rubber compound.
Or you can take the train.
