I'm probably going to jinx myself
but my 94 4.6L gets the following:
I just returned from two trips and closely verified my mileage and speedometer (new white gauges so I wanted to check everything)
29.5 mpg if I drive 71 mph (cruise control, no racing,
and 100% interstate) (speed limit 65 mph (I hate KY and OH! And does OH have enough state troopers!!)
25.5 mpg if I drive 77 mph (again, cruise control, no racing,
and 100% interstate) (speed limit 70 mph)
21.5 around town with some racing
4.6L, 3.08, non-posi, modified exhaust, no silencer, 4 new O2’s, new MAF, etc.
And 218K miles… maybe the engine is so loose, it doesn’t have a lot of drag and I get good gas mileage
