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?

I've always thought that if the average truck had it's undercarriage more streamlined to lessen air drag, then better mileage would be had at speeds above 25 MPH.

Mufflers shaped with tapered ends instead of oval or round with blunt ends. Axle housings with a tapered front facing or flair instead of round housings, narrower but larger brake drum dia. areas for a more streamlined frontal surface. Same for any frame cross-members, that catch air in a horizontal fashion at the underside of trucks.

Then there is the spare tire hanging in it's non aero holder resisting flow with extra drag. Well there trucks and other trucks, the ones I refer to are mainly ones used at being a second handy vehicle for work, hobbies, and recreation, seen driven daily.

There is a lot of junk underside that could be more better placed or shaped for less air drag. MYOP....

Engine block heaters for cold weather. radial tires back in the day when such tires were a new idea. fuel mileage gauges to find out fuel consumption at speed and idle. Electric radiator fans. Electronic ignition back in the day when they were a new idea. Grill blocks and air dams on the front of the car to assist aerodynamics. Lower viscosity transmission and differential oil.

My vehicle since new would want to stay in third top gear when hitting the freeway, temp gauge reading just off the cold mark when on the on ramp.

I made a foil/foam shield, mounted it ahead of the housing of the ECM engine coolant temp sensor, in order to block off the frigid wind blasts after start-up and drive-away at temps below 60* F an lower.

That allowed my automatic transmission to up-shift into O-Drive top gear on the highway at 65 mph, instead of the OEM perceived setting of higher RPMs in only third gearing/wasting fuel by minutes longer. Longer was controlled by the severity of winter outside temps, colder meaning a longer interval. The DIY protector only accounted fo the chill-down of the sensor area exposed to that time period of lazy warming under-hood temps, caused by the wind chill factor/blasts of moving air resisting engine warm-up noted by the ECM sensor. Worked for Me...& MY driving habits.d

three things have helped me get 120% more than the EPA rating for my car. That is three things have help me achieve on a 2010 Toyota Prius III, whose EPA rating is 50 mpg, an overall fuel efficiency is 60 mpg:

1) tire pressure gauge and tire pump - which I use to overinflate the tires to reduce my car's rolling resistance so I can *coast* longer on momentum. Along with using low rolling resistance tires this bumps me up about 3 mpg.

2) air intake grill blocking foam - which I use to help the engine heat up and stay warm when the driving temperatures drops below 60 F. So instead of losing 8 mpg in the winter time I lose about 5 mpg in the winter time to cold operating temperatures.

3) a ScangaugeII OBDII meter - which helps me me fine tune my hypermiling techniques by telling me when the gas engine is running or not (RPM/GPH) and how fuel efficient the gas engine is at a particular time (LOD).

I've been studying fuel economy using a 2010 Prius for about the last five years - there isn't any magic bullet and not every technique I have learned will work in all situations but rather I know a set of tools that when applied at the right time, at the right place, and applied in the right way - produce better than expected fuel efficiencies...

Nope. There is NOTHING that has been PROVEN to work.

If it does help, the manufacturers put it on the engine themselves.

No. Remember several years ago they were selling a magnet to fasten around the fuel line just in front of the carburetor? What a joke!

Like Boyrr stated I also trained my R foot to obey logical reality decisions/commands. The device is my shoe. Warm ambient air of 100-130F* is beneficial to the air/fuel intake of engines for correct fuel vaporization and economy, during fresh engine starts or restarts.

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 $$$....
