Post your avg mpg

[Vehi-Cross-Az]

this is interesting but great info..
mines been getting around 12.5 with a air intake kit
and green cone filter, and 17" wheels and 30" tall Michelins
Small 2" lift and normal city driving.

Today I did the first step and test and swapped mufflers.
Did a Magnaflow. 2" in and out 18" long.
Ill start another thread with pics and youtube link so you can
hear it etc.
My goal is to install a few mods every few tank fulls and see
how much better I can get my mileage.
Performance is secondary and I know it will be an automatic
improvement.

17.28 over the last four months (3013.6 miles/175.072 gal, but who's counting?) 265-60-18 Kumho's on stock wheels, 36 psi. PV1 catback. Everything else totally stock. No lift. 90+ mile daily commute - mostly highway, but with some long stop-and-go sessions. Just had my MAF serviced about 10K miles ago, and new plugs and timing belt installed a few thousand miles back. Mobil1 oil and filter since day1. Tranny and diffs are probably standard dino fluids. I never requested synth when I had them serviced.

I do NOT baby my VX when I drive, but I do keep it cleaned and cared for. I'm very satisfied with the mileage. I actually thought it was much lower until I started tracking it a few months back. I am also curious to see how the winter blend will affect mileage. I've also work from home a lot more, which reduces the highway miles and increases the city miles. The Christmas holidays resulted in a low of 15.8 due to the local shopping trips.

I would love to get 50mpg, but not at the cost of driving a tiny box. I need the style and performance that the VX exudes. The Jetta doesn't do it for me. Sorry. The Tesla Roadster would be cool.

combination city/highway/rural roads w/hills: summer got around 17.5mpg. currently (winter) got 16.2mpg. Experienced 22mpg on a highway trip to Vermont (a few years ago) with cruise and 23mpg on return trip with cruise.

Mobil 1 Synthetic everywhere.

See my profile for mods list.

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?

[Seidmanrob]

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

[protonvxmatt]
