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.

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
