NO nothing has blowed up, yet! But Ive heard it said and experienced it once with a 200hp outboard. What got me to thinking about his is the fact that my old F250 has been getting better mileage consistently over the last 20,000 miles. Really she has always got 12-15 mpg empty. Then it started getting that while towing and even better as time miles has rolled on. Last road trip i took to get the Skyhawk I pulled a 83 3/4 ton Sq body cheby truck up to Michigan before I skipped over to Ohio to meet with Denny. It got 15-17 with that big ass truck on the trailer and 16-17 with the Hawk onboard weighing next to nothing. Today I went 2.5 hours south to pick up some parts and left with 3/4 tank . Thinking I'd have to fill up before heading home. Im nearly back to the house and the trucks gone 417 miles on that tank with a 1/4 showing on the gauge. Thinking its gotta be broke. Nope! stopped to fill up and it took 21 gals on a 28 gal tank. Math says just under 20MPG. Shes got 284K miles on the 7.3. Only reg maintenance , couple of fuel pumps , couple alts and I replaced the turbo at 160 just because. Anyway now Im thinking shes got a nasty surprise in store for me.. I really hope not with the Nationals trip coming up soon.
