Imporved Gas Mileage

[jacks336]

Hey all I went to auto zone the other day and installed this


I also put a can of this into my tank


And my gas mileage went from 15.9 to 19.2 and finally joined the happy camper club

None of your pictures are working! I'm very interested as we recently bought a 2003 XE and are fairly disappointed with the poor gas mileage. Can you provide names instead of dead picture links, by any chance?

[jacks336]

the first thing was added a tornado. I know a lot of the people on this fourm swears it doesnt work but if did for me. #2 was to add a can of B-12 Chemtool (you can find it at autozone) its a fuel injector cleaner. The third thing I did was remove the o2 sensors and clean them with brake cleaner.

[jacks336]

Bad news I reset the comp like it says to do on the tornado box to try to get even beter gas mileage and it droped I am now down to 18.74 mpg but not bad concitering what i was at before.

If the tornado is such an invention I wonder why Nissan wouldn't put it in as standard equipment since higher mileage would be a great seller for an SUV?

I'm sure the B12 and 02 sensor cleanings were entirely responsible for any mileage improvement. The Tornado is absolute crap and really only helps on carbureted engine.
It's a $10 max piece of metal sold for a rediculous price. If it worked, every auto maker would install one at the factory like Schlud said.

Just curious as to how many tanks you ran through before you came up with the improved mileage. Several things can affect gas mileage on a per tank basis. Even a good tailwind...

im on my 6th tank since i installed all the items I reset my comp on the seccond and have remained between 18- 18.8 for four tanks in a row

[whitenbluesX]

i think i'll try that injector cleaner and cleaning the o2 sensors.. im lucky if i get 250 miles out of an over-filled tank im fairly new to the whole tornado thing- but even from other make cars/trucks everyone's said they're a waste of money

[akordboy]

how do you clean the O2 sensor??

[jacks336]

i would get about 250 miles as well. Now the fuel light comes on at about 298 miles. as for the o2 sensors I removed them and sprayed them off with brake cleaner.

[akordboy]

You said removed them. Where would the second one be??

[OffroadX]

There are 4, 2 per side, one before and one after the main/upper cat.

[Where can I find the o2 sensors? Is there a online diagram, or does anyone have a diagram they could email me.....

Check engine Light came on and I have 2 O2 sensors bad.

Thanks..
