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 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.

Removed my tailgate off my truck and have been getting 1 mpg better so far.

I did install a gismo under my carburetor at the intake manifold, it sandwiched in between below the carb base. I only traded misc. item for it My friend didn't know what it was.

I had seen them advertised in different catalogues, so I installed it on a Ford 53 Merc. V/8 engine "Flat-Head" with a "Strongberg" maybe "Stromberg" design carb. engine swopped into a "40s" model vehicle.

The gadget was a fuel/air whirling blade vaporizer, powered by intense manifold vacuum intake air flow, and made a high pitch razz type sound with a after-market dinky air cleaner.

It only caused the engine to idle much faster when hot(normal operation) I think it had a temp valve compensator to just lean out the idle mixture only thus increasing that speed(impressive) at that with the whirling noise also as the engine revved up.

I removed it fearing the impeller blades would wear and break off and go through the engine internally. Gas prices then, about $.23--.28 cents a gallon.

No. They are all gimmicks.

The only one that gains is the guy that sells the product. He is sitting quite comfortably on his yacht in the Caribbean laughing.

Yes, I did once on a 1992 Ford Escort. It was the Platinum Fuelsaver by National Fuelsaver Corp, or better known as "1-800-LESS-GAS".

I can tell you it didn't improve the fuel economy of the vehicle, since it was a modern vehicle with a computer controlled engine management.

But the one thing that I did find that it did do was cleaned up the engine. After each oil change, roughly every 3000 miles, the oil got cleaner. I installed it when the vehicle had about 80,000 miles on it. And before I installed it, after about 1000 miles the oil would start to get dark to a blackish tint. But after I installed it, the oil got cleaner, to the point that it would stay clear all the way to 3000 miles. It took a few oil changes before that happened. The vehicle stayed that way up until my wife totaled it, which was about at 160,000 miles.

Just from that stand point, I am pretty sure I was saving a lot of wear and tear on the engine. But the thing is really expensive!!!

Installed a K & N air filter mainly to reduce maintenance, but MPG did go up some (almost 1 MPG).

Just considering a DIY fuel saving project for our truck, It should work during all seasons of driving. I don't expect 30+ GPM but hope for a lot closer than 22.7 max so far.

I have found that any extra streamlining done has more affect on vehicles with small engines than the larger V6...V/8's powered ones It seems the smaller engines due to low end gearing, can handle the extra added weight factor if slight, driving city.

Those engines still must work harder driving highway in the taller O-drive
top gear ratios, the aero advantage helps but often isn't noticed, and wind direction is a big factor also not so much the weight increase unless there are hills involved daily depends on the(terrain)and special driving habits adopted?.......

I can remember back when some cars had such weak engines that the driver must shut down most accessories to help their engines gain a bit of HP. back to merge speed onto the inter-stats during the 55 MPH zones "laughing"
was a HOPE! to succeed!.......

If tonneau covers and/or caps count on a pick up truck - then yes. Neither were for fuel saving primarily; neither improved my mileage, even though they often are said to.
