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?

drgeeforce ...Reply; Yes the extra wattage panels you are using will most likely keep your battery peaked and a bit warmer on cold days as far as chemical temps go.

One of the best things I did many years ago for my daily work vehicle, was to double up both battery cables the positive and negative. The engine starter spun that engine over like it was on steroids, on Winter days. I just bought extra # 2 gauge cables and then paralleled them from end to end on the connections(delivering more good amperage)to the starter motor.

The results was less voltage drop at the work load, and less waste in heat/amps lost, for that duty cycle. DIYing pays off in benefits! Cost varies, and bargains are out there.

@dontuknowOH, I use two 16 watt solar panels to lessen the alternator load on the engine. I sure it helps with LED daytime running headlamps @ 14 watts ea. I drive an SUV and both panels go on my roof rack.

Three of our vehicles, I DIYed altered the heater coolant supply hoses. A cheap project to insulate both hoses. The benefit worked better on vehicles that had a belt driven cooling type fan (non electric) type.

The benefits were better fuel savings on cold and cool-down restarts, mainly for seasons other than Summer. The other benefit was more intense quicker heat at all cabin vents, The effects were noticed when daily temps drop into the teens and lower, even at idle engine speeds(RPMs).

Electric fans or not, I still keep the insulation in place, using along with any considered healthy coolant system, maintained. Ohio climate. WFMe!

Just K&N filters, but more for simplified maintainance than the incremental fuel economy increase that it gives.

A bad driver can increase their vehicle's MPG by up to 40% by letting a GOOD DRIVER drive them around.

Other than that:
-- Over-inflate your tires (but savings is lost with need for more tires).

-- Take OFF The stupid, after-market whale tails and other foils which only add to a vehicles drag: you're not driving NASCAR and don't have to worry about traction at 220 miles an hour.

-- Leave your pick-up's tailgate UP (it creates a 'bubble' of air in the bed which air flows over)

PLEASE NOTE: THERE ARE *NO* ADD-ON DEVICES ON THIS LIST

On my 1972 Plymouth Scamp with slant six., I had the pully driven fan removed & an electric 12Volt fan installed. In my northern Washington state, it was nice that the fan was off most all the time. I hoped for more, but only noticed ~ a 3 percent increase in my mpg.
On a 1980 Toyata Tercel, I had a mpg computer installed. The instantaneous mpg readout helped me gain some mpg increase due to induced careful driving.

Over the past 5 years I have used a Solar charger hooked up into one vehicle. Never yet checked for a improved fuel gain in MPGs. The main purpose was to keep up the vehicles battery charge, when not driven, during the peak higher gas prices, then near $4.00 gal.

The 5 watt S.. charger works to peak My battery each daylight amount of hours, more when the sun intensity is full, the energy free & capable. Less alternator work duty is the result when engine runs. The battery always gets a free charge when the vehicle is idle/shut off.

Hope for a sale deal for 15 watts, 5-15 watts isn't much but would work for My purpose, the 1.5 watt type are rather small, but usable, in parallel hook-up. Any free fuel savings is a side benefit.... aIsi!

Only one that I traded for, way back in the "60's" It only idled My engine faster, made noises during engine rev-up, took an hour to install, resulting with no fuel savings, but a new impressive under-hood noise.

Noise similar to a very sick operating vacuum operated "Wolf Whistle" >>>> novelty horn still available today. Those horns work fine, no toot type.

I've seen tests on driving with empty truck beds during either fashion (tailgate up/down)results. My bed has a forward low profile tool box and is currently loaded with saw-horses, drum barrel, and some other bulky items.

Not always but mileage seems noticeably better when the stock tailgate is completely removed, then with only a net restraint in use or a ladder rope to hold any objects secure. Partial filled beds seem to alter the air drag, regardless of extra weight added.

I can go with the lighter Foot mobile devise, and speedometer view/cruise on most any time for fuel savings. Never weighed My tailgate yet!

Below is from http://www.discovery.com/

This is a small part of the article.

Closing the tailgate actually improves fuel efficiency because it creates a type of airflow called a separated bubble within the bed of the truck. As wind rushes over the moving truck, that bubble of slow-moving air deflects it over the raised tailgate. By guiding surrounding air over and across the bed of the truck, that vortex effect prevents added drag.
