I heard this will improve MPG?

Those "additives" are a SCAM.
They are made with a chemical one molecule different than MOTHBALLS.
People used to put MOTHBALLS in their Gas tanks in the 1940s, it didn't work then, it doesn't work now.
Automotive Engineer; John Fanning says they are ONLY a "money-making" scam, and DO NOT work as advertised. http://www.chiefengineer.org/content/content_display.cfm/seqnumber_content/2517.htm

 

Ya.
Bought a RIGMASTER using OOIDA's member "discount".
The POS never worked right, I could NEVER find someone who could actually FIX it. Total engine failure 10 days after warranty expired. OOIDA wouldn't stand behind their "loyal" member to get it fixed or replaced. Last straw....I cancelled my OOIDA membership and haven't looked back since. OOIDA looking out for truckers?? Ya, right.

 

Turbo3000D??????

You don't really believe in that magic pipe nipple do you?

If you do, I got a bridge I can sell you cheap.

 

How much are you askin' for that bridge, Tom?
I have a bridge collection and I might be interested ---- if the price is right.
Also, does it cross water or a canyon?

 

yeah...my math was a little off there LOL

they do have the sound deafening mats liked used in car stereo systems...wonder if you lined the inside of one if it could help kill some noise...

ill wait and see what cowboy has to say about his before i get my hands on one...i do know for sure we are going to buy one before this summer though..idling the truck cost a #### arm and both legs now a days...

 

i put one gallon of oil (burnt oil when i have it)in my fuel tank when i fuel up,i figure 1/4 mpg gain

 

cant hurt if it doesn't work

 

so what ended up happening? get a new one?

 

Good way to get rid of your old oil if nothing else

 

Yes it is definitely true. If you click on the link in my signature it will take you to my site. I have a video on there with proof of it working in a 98 Jeep Cherokee. The Rigs our units have been installed in have seen a 1 to 3 MPG increase.
No, it does not force water into your engine - as long as you don't over fill the unit you will be fine.
It is well worth the money. Even if you only see a 1 MPG increase from it you will make your money back plus start your savings on your first trip from lets just say North Carolina to California and back.
It is also extremely easy to install in big rigs, you do not need to mess with the computer or anything. That is only with gasoline run engines. With a big rig you just mount it in the engine compartment, tap a barb into your air intake, hook your cell up to it, hook up power, install an amp meter for the cell and a 30 AMP Fuse, and you are good to go.
You will immediately see a gain, not only on gas savings, but also horse power and your engine will run much smoother.
