Years ago, when gas was still cheap, my dad installed a gasoline pre-heater which used the heat from the engine coolant to preheat the fuel. (I'm sure it voided any warranty on his engine) He noticed some improvement, but it wasn't worth the money.
What's your experience?

Only DIY-installed devices also keeping vehicle junk, items not needed for a reduced weight advantage, makes sense mainly where stop/go/frequent acceleration/braking describes the daily driving conditions.

If a small speaking voice devise would sound off each time the driver hit the brakes/Go pedal, like a sound of "Woops.... Again" or " Nervous Foot Today!" Sounds Dumb, but habits are reality just like fuel/energy/cost savings.... "Ignore".... is the most common choice!!! = Tailpipe $$$....

I've never installed a fuel saving device, but I have removed emissions junk to get better fuel economy. Adios catalytic converter!

Never bought one, only DIY what works, as a project/benefits/low cost, involved.

Not recently, still using the older installations. Winter will bring about something to consider.

Gasoline burns better and more economically, when cool.

A Wise older Uncle always said "First always put on your Godly thinking cap" before you start the engine!

If everyone did pay more attention to their selection of choice driving habits, the fuel consumption overall would come down, prices also. they don't drink that Stuff yet internally, I hope not.

Three times I installed a FSD just for my own use, years ago several on older vehicles, proved beneficial. Todays vehicles are Razor sharp on economy OEM tuning, except for a few glitches...far above average!

I put a large air dam on my suburban, that I built my self. Worked pretty good. It improved fuel economy and apparently it forced more air through the radiator because the engine didnt heat up as much going over hills.

Most of the best ones from years ago have been adopted by the automakers into new cars. K&N air cleaners still help, though, and a higher voltage spark from an improved coil and/or wires can as well. I get a small boost from nitrogen tire inflation keeping tire pressure up. You can also increase tire pressure, but that can alter handling characteristics and traction.

Keep in mind that alterations for better performance/mileage tend to increase maintenance requirements, though.
