Hey, new guy here, highschool student on a budget

Sounds like a lot of work for nothing, but if tinkering makes you happy...

I've read about a product in a "base newspaper" back in '97, and have been using it ever since,,,,,it DOES HELP . I've also began using those plugs that're advertised in Pop Mech/pop Sci. they really help in the "FEEL"/Running of my old truck.. I've not done a Mileage loop yet... but I've just recently changed over my 4 tires, from "off-road" to "hyway" types.... I've blocked off some of the grill, am "Going to" put up a "curtain" underneath , to smooth the flow of air under the blazer,, and "moon-disks,,and a pair of skirts....will be coming,,,,,,then, going from 2-into 1,,,,,to "Dual" with headers, flowmasters, (while still keeping the O2 sensor)..... and for my LAST THing I'm going to do is to change the ring/pinion from 3.73> to down to a 3.42...... it'll still be 4x4 capable, but,,, I'm believing that I should hit "25" hwy,, and hoping for ........? 18 City? Please, please?

That's quite a list. Congrats on all your efforts. Considered a tonneau cover? It seems to work for lots of people. Is it a manual? You could adapt driving technique more with a manual. You could also run a deep-cycle battery and an alternator optional kill switch. Take off the A/C belt in the cooler months at least.

But more importantly, do you need all this vehicle? Do you drive off road? Do you work in construction? If you don't, your single best mod would be to trade for a good used smaller, manual transmission vehicle with a smaller engine. You could easily double your mileage. In a couple years, your "new" vehicle will have paid for itself in savings over continuing to drive this behemoth.

Good luck!
