This has been discussed over and over but I haven't seen a comprehensive list developed. Can we TRY that here - each poster simply copy the latest poster's list and add their own points. (Leave discussions to other threads and just stick to point form itemization. Embellish or create improved comments rather than trash a prior person's item - whether it's rightly or wrongly in the list at all.)

Maybe don't worry about order - it's highly debatable as are my categories

Generally Easy and Cheap
- improve driving style
- remove roof rack crossmembers
- higher tire pressures
- use a winter front in the winter (air dam effect and impoved engine temp.)
- carry less weight

Less than roughly $500
- engine tune up
- after market air filter
- after market exhaust
- diesel chip

Over $500
- change to highway vs offroad tires (reduced rolling resistance)
- remove push bars, etc.

Involves work, testing and uncertain costs and results
- improved aerodynamics
- - air dam
- - underbelly smoothing
- - rear deflectors

- hydrogen generators :-) (just kidding)

 

Generally Easy and Cheap
- improve driving style

- Scan Gauge II (or similar) to monitor Load, Throttle Position, manifold pressure etc. to help improve MPG driving style.

- remove roof rack crossmembers
- higher tire pressures
- use a winter front in the winter (air dam effect and impoved engine temp.)
- carry less weight

- keep your engine clean
- proper weight oil
- verify proper tire alignment

- Flux capacitor serious...

 

I found an easier way to save fuel. Get someone else to drive you. :-)

 

That doesn't work as well as the Bussard Collectors.

A highly fictionalized variation of this concept, called the Bussard Hydrogen Collector or Bussard Ramscoop appears in the Star Trek saga as part of the matter/antimatter propulsion system that allows Starfleet ships to travel faster than the speed of light. In the saga, the ramscoops attach to the front of the warp nacelles, where (when the ship's internal supply of deuterium runs critically low) they collect interstellar hydrogen and convert it to deuterium and anti-deuterium for use as the primary fuel in a starship's warp drive.

 

Dude - I'm a Star Terk fan but....

 

did someone mention flux capacitor ?

Holy Crap. It is 15% off. I'm getting mine NOW.

 

Don't buy from them. I bought the engine oil bypass kit to help reduce pumping losses and found that my mileage went UP. I'd like to get the dual o-pipe but won't buy from them. I'll wait until somebody else carries one.

Oh boy...

 

Generally Easy and Cheap
- improve driving style

- Scan Gauge II (or similar) to monitor Load, Throttle Position, manifold pressure etc. to help improve MPG driving style.
- Vacuum gauge (cheaper?)

- remove roof rack crossmembers
- higher tire pressures
- use a winter front in the winter (air dam effect and impoved engine temp.)
- carry less weight

- keep your engine clean
- proper weight oil
- verify proper tire alignment

- improved aerodynamics
- - air dam
- - underbelly smoothing
- - rear deflectors
- - trim windshield w/electrical tape smooths airflow, cuts noise and fixes leakes too :-)
- - Vortex Generators (air tabs)
- hydrogen generators :-) (just kidding)
- Flux capacitor serious...

Note: sounds like Vortex Generators beat Hydrogen Generators.

Best way to get better mileage:

Stop driving the Excursion, drive something that gets better mileage instead.

Exactly! That's what I did 2 weeks ago! Drving a 25mpg vehicle now and it's nice saving $$$$ I will only drive the Ex for towing, the rest of the time it's parked in the garage!

 

Yes - I guess walking works too. I've added it below..

Generally Easy and Cheap
- improve driving style
- walk or take a bus or borrow someone else's car, take a balloon (or whatever involves just not driving the EX which has the benefit of reducing its depreciation)...
- remove roof rack crossmembers
- higher tire pressures
- use a winter front in the winter (air dam effect and impoved engine temp.)
- carry less weight
- drive something else (if you have it)

Less than roughly $500
- engine tune up
- after market air filter
- after market exhaust
- diesel chip

Over $500
- change to highway vs offroad tires (reduced rolling resistance)
- remove push bars, etc.
- Buy something else (if you have to)
