Gas milage increase!

[VehiX]

Hey folks -

This may seem obvious to some but I just wanted to point out that I have been seeing better gas mileage from my VX after performing the following maintenance:

• Flushed and filled tranny fluid
• Changed out the PCV valve
• Flushed and filled front and rear diff fluid

I was previously getting about 270 miles before the light came on. Yesterday I managed to get 330. When I filled up at the gas station, I put in about 20.xx gallons (cost me friggin $65.46!!!). My driving style has not changed, so I can only guess this basic maintenance helped me to achieve the better mileage

Anyone have opinions on this?

Current power mods:

PV 1 exhaust
Basic cone air filter

Well, I changed my fuel filter, and switched to a regular K&N box filter, and I noticed an increase in gas mileage. I also change my oil and PCV every 3000 and have been doing so for a long time. Keeping things clean definitely helps. I don't know about the tranny juice, but it may also increase efficiency, which may in turn help the VX use less power to shift, etc, which may have helped, but now I am talking out of my @$$.

I am about 10k miles away from doing my tranny fluid/filter and diffs again.

That little PCV does a lot to increase mileage. That valve lets unburned fuel vapors, which are prsent in the crankcase, into the intake where it can be drawn into the cumbustion chamber and burned. The tranny juice helps too. Less slip and better grip in the clutch packs.

I have NEVER changed my transmission and diff fluids before. I need to do this and dont want to pay a shop. how difficult is it and is there a how-to on here? with pics?

This helped get me pointed in the right direction...

I topped mine off the other day using this setup.

Is it just a myth when people say. You dont want to mess with your tranny much. The more the mess with it the more likely it is going to die quicker?

Not to hi jack.

But I plan to do this as well since I am getting 13.4 mpg. I plan to consider de-lifting as well.
