I started tracking mileage again once the supercharger went in - prior to the SC, I was getting 12-15 (Hotshot Intake, PV1 Muffler, 87 Octane gas, Tire pressure at 46 lbs). Now I'm running a CAI with Green filter, PV1 Muffler, Supercharger and 93 Octane gas, Tire pressure at 46 lbs).

7/18 12.6
8/5 SC Install
8/15 14.65
9/10 19.897 (roadtrip)
9/27 11.81
11/9 Oil/Filter/PCV change
11/24 18.49 (roadtrip going up)
11/24 17.668 (roadtrip coming back)
12/7 14.24
12/13 15.92
12/19 13.80
12/23 15.56 (roadtrip going up filling 1/2 tank)
12/26 15.44 (roadtrip coming back filling 1/2 tank)
12/27 17.28 (roadtrip next day fill-up)
1/2 16.0

What I've noticed is that during the summer months the mileage is crappy (summer fuel mix), then in the fall it gets really good until it's really cold, then it gets really good again in the spring until the summer fuel mix comes again. Also the mileage starts getting bad towards the end of every other oil change, when I change the PCV and it gets better again. Gassing up the tires give me about 1/2 MPG more, and I think the 93 Octane gives me another 1/2-1 MPG more but it's hard to say with the SC installed). The engine was running towards the hot end with a cone filter pulling engine compartment air - the cold air intake makes the engine run considerable cooler (barely goes above the halfway point, like it did before the SC). When the SC was drawing engine compartment air, the temp always ran just right of center and crept up to "hot" right when running hard or stuck in stop-and-go interestate traffic.

after maket intake, 919's lift about 3.5 inches, 33"s tires, 17 inch rims, and i'm avereging on highway only 11.11111 MPG, it sucks my balls out, but now i dirve it like 2-3 days a week, and i enjoy it, and if i cared so much about milage i would of sold it by now, but i love to drive the vx and the vx love for it weighs more then it consumes me. the only problem i have is that i was doing 350-400 miles a tank full, and after my trip cross country now i'm doing 220-250 mpg a tank full. it sucks and to this day i'm still trying to find why and trying to fight some gay grimlins that some of you guys now of. But i still love it just bought a roof rack can't wait to get it and show pic's of it, from the finish inside dash project to the new out side look. the only thing that sucks is that i got the rack shipped to my parents house back in florida and i'm in cali so it's driving me nuts knowing i could of had it with me already.

Are you compensating for odometer error? If not, you are getting about 11% better mileage than you think, due to the 33" tires being 11% larger than stock.

[CoastieCosta567]

nope, never thought of that, so much more will that be like 12.2 mpg?

Yep, about 12.2-12.3...maxing out the air pressure (max rated on the sidewall) may help a little too.

[CoastieCosta567]

thats cool, sweet, thanx Ldub.

My '99 is bone stock and I get 16.8 to 17.5 in mostly city driving.

I'd like to know how the guys with turbo/super chargers fair in the gas wars? It can't be good. Single digits? I didn't notice any posts from anyone who has made that mod, but I'd like to.

I'm supercharged and have mine posted above. I don't really notice much of a change - if anything I'm getting better mileage.

On highway trips with the cruise set @ 65 I average a bit over 17.5, but kickin' it around town it's about 10-12...the S/C has turned me into an even more hopeless acceleration junkie..

I'm supercharged, 3"+ lift on 33" tires, Amsoil syn in everything...even blinker fluid.

[protonvxmatt]

i avg close to 15-19 mpg. i have 33 in nitto terra graps, flowmaster 40 series exhaust, light bar on roof. plus a few other things

[Solitude]

15mpg 255/55/18 terra grapplers.. no lift no intake synthetic oil

[SuperDave]

Twelve mpg combined. All stock but for Yokohama Geolanders and Pioneer AVIC-N2 with amped subwoofer. VX is a gas and oil junkie, but I'm the enabler. I could get better mileage by coasting to stop lights.

[alanbradley]

14 to 15 combined, depending. I got 19 on a recent motorway (highway) run. All of those are mpg(US) rather than mpg(Imp) - you guys have longer miles or something...

Its a bit of a shock after my Yaris diesel that averaged 48mpg(US) and with fuel prices at well over $2/litre its something of a wallet stretcher but I knew all thsi when i bought it so...
