Real devices/additives that will save on Fuel gas mileage?

I would think "no", because they mention on their site that you must have a cell that is sized to your application, and a cell sized for a 15L diesel will "flood out" a small engine... two would provide the same effect.

 

Okay, now this whole thread is starting to sound like a setup and an advertisement and all 8 of Hardwires post are about this product.........

 

I have some background in aviation and motorsports so am much more inclined to believe that aerodynamics would play a huge role in fuel economy with a truck and trailer, particularly vans.

For example, what about the various side skirts and "accordian" like truck to cab baffles?

Obviously the manufacturers spend considerable time at economy to attract fleet operators which is why, for one example, Freightliner has the new T700 which is even better than the T660.

I would really like to hear from some real world drivers out there. If you are pulling a flatbed with, for instance, a couple large pumpjacks using a 389 Pete, there is simply no way you'd get the same mileage as a 387 pete and a modern van all else being equal. Right?

Consequently, it seems there are enormous advantages yet to be had in the trailer aero package and wheel/tire effect on aerodynamics. Plus tire/road friction.

There is one company claiming 7% increase with it's skirts. Even if they exaggerate, how much is realistic? And yes, I know they are prone to damage and are weird looking, I am just using them as an example.

If one is talking $4 per gallon diesel at a conservative hundred thousand miles per year, even a small percentage increase in economy is significant, right?

But maybe I am completely insane, so what have you experienced drivers have to say (about the post not my sanity!)? Any real world experiences would be interesting.

Thanks!

 

I've been a mechanic (technician, woo, hoo) for 40+ years and I have yet to see any additives or add-ons that will provide a cost effective increase in fuel economy.
They will however, definitely reduce the mileage of your wallet.
The best device? your foot.

 

I had a stint in the chem. buis. All the MPG claims are BS. Both fuel and oil additives.
Dry gas does get water out of gasoline simply by the fact that alcohol mixes with water gas doesn't.
Anti gel-waxing obviously works in diesel.
Some of the oil stop leaks help.
104 octane boost did help with pings at least back in the day.
Barrs leak with the copper in it for radiators is incredible saved me a ton of work on two cars. I recommend it big time.
Do your maintenance on time.

 

The best tool for fuel mileage is your right foot!!!!

 

The guy needs a better proof reader on his website.

He informs me his calculator will:


[FONT=arial,helvetica][FONT=arial,helvetica][SIZE=-1]This calculator will compute your truck's Miles Per Gallon and forecast your gasoline expense for one month and for one year. It also allows you to see how much money you would save if you were driving a truck that got better gas mileage. Only fill in the blocks to the left of the yellow line. The results will be shown in the blocks to the right.[/SIZE][/FONT][/FONT]



Gee my truck burns diesel fuel so my gasoline expenses are quite impossible to improve. Second rate inventor (this design has been on the internet since the internet began) selling a third rate product.


If you want to try this yourself google browns gas. I know a couple guys that tried it, and one on another board. All soon realized the system is ineffective in the big gains people are touting here.


Best device for fuel mileage improvement is throttle control class for your right foot.

Furbo300f(as in fail) makes an excellent paperweight. Air tabs cause more drag than they eliminate. Side skirts are only on trucks because CA mandated it but may actually work if you believe their director who falsified his doctorate
Good tires, an air gauge, good habits, progressive shifting, clean air filters, and clean fuel are the keys to fuel mileage.

 

A racing board I read has a KW power train engineer on it, I was talking to him about fuel mileage when I had my T2000. When I brought up the idea of building a belly pan for it he mentioned that the areo guys at KW lobbied really hard to get a belly pan on that truck but they lost that battle due to serviceability. He said it made a HUGE difference, but I couldn't get any rough numbers from him.

 

Not to mention getting it by the NTSB. How are you supposed to inspect the undercarriage with a belly pan?

 

Not totally true. The programming put in today's engines isn't the best for performance or fuel economy. They can only do what allows the engine meet EPA standards. The engineers at Cummins\Detroit\Cat ect aren't stupid, the stupidity is forced on them by the government.
