Yeah, you're being unfair to yourself if you're looking at blizzard-MPG. See how the summer goes and prepare for the next winter with block heaters and 99.9999% grill blocks, .

99% grill block on this would cook the tranny, so that's not an option. 50% is about the limit there. It'll definitely do better in the summer, but doing 60 on flat ground with no wind, it still gets about 19. I've seen 21 once, with the exact right hills, cruise at 59, and a slight tailwind. It was around 40*, so no A/C, but not cold enough to really kill the mpg. For mine, it really needs taller gearing, as a 360 doesn't need to turn 1750 rpm to do 60mph in this thing. Too bad the gear vendors OD units are so expensive, as that would drop my RPMs a lot (just under 1400 at 60, or about 1500 at 60 if I geared the axles a bit lower for better off-road crawling).

That is not accurate . 3-5% is the minimum in most cases and anything over 10% is illegal without the proper signage. They can't require usage of Ethanol if there is no supply for it anyway, they can only mandate that an oxygenate be used and Ethanol is the most popular with MTBE illegal. It is legal for them to sell Gasoline with ethanol in it in many states without signage, in that case any signage is voluntary.

Coil on plug is the new thing instead of distributors. Meaning spark advance is decided by the ECU. You can get a tune for that .

Even the distributor based Jeeps (91+ only for the 4.0) have the spark advance adjusted in the ECU, as the coil is computer controlled.
