Got the scoop on the truck. It was a wrecked fleet truck which was then shipped over to Cambodia sans the engine/ front. Then someone took a front clip, welded it on and then dropped the 2.3 Duratec motor in it because it then fits in a lower import tax bracket. That's why it was only $27,000 vs. $40,000. Haha, now that's what I call frankenstein.
According to the VIN it was originally a 4.0 liter truck.
Anyway, changed oil (20W-50 down to 10W-40 semi synthetic), filter and trans fluid on the Hyundai. Newest results?! 26.7 mpg US.....
Not really sure what to make of it, at this rate I'll be getting negative mpg soon.
