What mileage does your slant six powered ride get?

Not to crap on your parade but that’s with an overdrive and the final ratio is what?
2.82 w/a .69 OD ratio? No wait, manual, it’s higher right?

Where are the guys that claim 30, 35, 37+ mpg’s?

For the OP, that’s what I got out of mine and I promptly dumped it for a 318.
The guys getting mid 30's aren't running a 4:10 gear.
