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?

Still have two more DIY ideas to try out and then two others at a purchase cost for material, checking for bargains, no hurry.

Probably at least 5 or more way back to the days of owning vehicles with carburetors/distributors/such. We always called them Engines, and not motors then, and still today.

For a to/from work ride vehicle, real simple type no frills just the basic electrics. They make an under-drive pulley for the alternator drive, which reduces the BHP needed to propel it (saves some load torque)on the engine.

Also the past trend for some was to chose narrow front lighter in weight alloy wheels with narrow slim size tires on the vehicle(pro street drag look)installed up front.

That should save some fuel(dynamic lighter) creating less rolling contact resistance (smaller foot-print) by more air inflation, less hydroplaning, better aerodynamics, less Inertia affected weight to put in motion during Stop/Go repeats.

Stay with reasonable rear size tires also, even if the look trend is to go larger, remember your econo"s engine size to keep from going overboard on the tough look! Maybe they make plastic traction bars?..... G-Luck1 Hint... alum... old Fairmont bumpers can be modified to fit some smaller rides. but salvage yards grab them up! as junk aluminum...."DIYers"

Every time I get in the car I install my wallet in my pocket. That's enough to make me think of driving so as to get better mileage.

Older vehicles driven may need a lubed go pedal linkage, cable, shaft, and pivots. Under-hood temps over time dry out these areas, often repeated unnecessary engine surges then are a result unnoticed by the driver.

Saying some fuel could be saved just by having those areas checked, then corrected. Really if taken care of the better affects will often be noticed, same for many automotive door hinge points (need lubed).

That service often ended years ago with the era of the local family operated service station. Requests must have taken priority these days. My DIY abilities or My mechanic will take care of this if asked, no charge!

Any fuel savings is a benefit right! The door lube thing helps you Hurry/Nice..... A smooth pedal relaxes your right foot....... Ha!

Sure here are a few. Radial tires when they came out made a difference also in handling. Engine block heaters also help with less cold starts. Mileage meters that give direct feedback on speeds and fuel consumption. tuneups and low resistance air filters. Multiviscosity synthetic motor oil and other which may or may not help.

My thoughts are: We have EFI by port, direct injection, and throttle body older types. My wondering involves: Why don't todays vehicles have Partial Air Direct Induction to the combustion chambers? Along with natural aspiring control for regulation, then realizing that a high air pressure device would be needed as the supply.

I realize that more oxygen creates more thermo heat if added to combustion, still a better complete burn cycle would be more productive with performance/economy before it goes to waste exhaust. HMmmmm?

I know no one wants melted pistons, temper less compressions rings, burnt valve metal but still wondering..... about that.....

I've got some ideas for my truck, already have the parts/items necessary for a revamp. I did one installation 5 years ago and that helped/benefited in two ways.

Still I wanted to try another trial, mod rather for the cooler seasons like for operation during Fall/Spring/Winter. Any thing to better the vehicles economy drivability is worth the time as a DIY'..r

When driving shopping routes, zoned 25 - less than 50MPH. or even 55MPH. Then putting simply more distance between your vehicle and the one you are following becomes a fuel saving action.

Yes there will always be another vehicle move over into the extra space ahead of you when in motion, ease off a bit or hold. Staying off the brakes as much as possible along with paying attention of the T.. Lights and stopped traffic ahead.

Often the vehicle will turn right and free up that space and no braking on your part saves momentum $$ for your vehicle. The hard part is breaking the habit of wanting to always then attempting to close the following gap ahead, that is ok when coming close up for a necessary stop motion(traffic interval).

If you notice the repeated on/off brake lamps of many vehicles ahead of you, that signifies what I'm trying to avoid for the fuel savings, their actually using extra fuel up for poorer mileage with out any idea of why usually. Min...ute seconds may be the only reward for all the brake lamps ahead lite. Keeping distance, steady travel motion, less braking/resuming, less total stopping, results in less fuel loss(your F.. Tank) = NICE ! Your foot doesn't know when the F.. prices rise same for driving habits!
