I understand as most people I been around never understood me.
when I was in college in the 1980's I commuted 75 mile round trip every day in a 1973 Chevrolet 4 door Nova I managed to average 24mpg yes average 24mpg with a V8, I built an engine just for gas mileage, a 307 & geared it 2.73:1 I also built a warmed over 350 that managed at best 14mpg, that I played with, as I couldnt afford 2 cars so I had two motors & 2 rears my spare rear was around a 3.50:1 & I could change out motors & rears in several hours & cruise & maybe pick up a race, on Friday, & Sat nights & Sunday night swap back to my economy motor. there was no rear seat, only a thin piece of black carpet, & 2 carpeted wooden drink cartons remember those? that was my rear seat, & lightweight front seats with a blanket over for padding, hood bracing & trunk bracing was cut out & hood pins installed, rear doors were gutted windows were fixed to not roll down & regulators removed, & carpet glued to cover opening inside of door. yes it was lightened quite a bit.
My dad caused me to be like this as he had a muscle car, & an economy car, did everything he could for more power in muscle car, & everything he could to get better mileage in the economy car which he commuted to work in 130 mile round trip every day until his death.
lowering the front slightly, helps with some vehicles, I am not talking a low rider, but a 1 to 2 inch front drop can pick up 1 to 3 mpg in my experiences. also raising compression helps, but with todays gas, & unless want to fool with alcohol water injection, or octane boosters, I need to keep under 10:1 compression for daily drivers, a mild port, & ccing the head, & fully balanced / blueprinted bottom end, removing any unnecessary accessories, like power steering if equiped & converting to manual steering, air conditioning, removing rear seating, sound deadning, switching to lighter wheels for less unsprung weight, on some vehicles I have swapped to smaller alternators.
as for my old beetle, most people claim 22 to 28mpg out of a carbed 1600, 25 to 31 out of a fuel injected motor, yet I managed 36 mpg out of a carbed engine with a 1.5 mm oversize bore stock was 85.5 & I went to an 87mm bore to get 1641cc & mild cam, with a 4.12 gear but I rear & learned alot & mixed parts from different years that I believed would help me raise my gas mileage, like earlier motors smaller ports for better throttle response, smaller carb from a 1200, jetted for my application, & managed to pick up a 3.88 transaxle, but never installed it. still have it when ever I want to fool with it again. I also had a 1915cc motor built which is a 94mm bore with dual carbs that I played with. lol sold that but still have the carbs, & even then I had 8 different sets of dual carbs trying to see which gave me best mileage when playing.
as for a 4wd, actually I will probbaly need a 2 to 3 inch suspension lift for my other land, as I know what I need to travel over, plus I would like to be able to drive down my back yard here.
I used to could get into the beguining edge of my other land with a 2wd truck a 1960 Ford F100 lifted not sure how much, but it was quite tall, I built it as a teenager, & had 20 leafs springs per side in rear, full leafs, along with a lifting block, also had 12 full leafs per side in front, plus a 1 inch lifting block. that did pretty good, but still had trouble due to length of truck, & lowness of solid front I-beam axle, it had around a 4.25 gear. I mainly cut firewood & sold it to help pay for my car addiction. but even that couldnt get even 1/2 way into my land, & never took my first wifes Tracker in there as it was to low, it had wide lower profile tires with just street tread, & by the time it needed tires a more agressive tire was installed, but not as good as I would want, but still enough to get me to like the trackers from then on.
I even have an old junked Plymouth Horizin in my back yeard. it was the "economy" version, not the 2.2 that everyone knows, but a 1.6 liter cam in block Peugot motor from factory it came with a 4 speed, if car had not rusted out, I was going to do a 5 speed conversion & try to go through motor to increase power so I could pull that 5th gear, it got around 40 to 45mpg, & I wanted to see what I could do to get more. lol
