Some stats' on VX mileage

[Cyrk]

LOL... I get about 215 a tankful and that is squeezing it to the very last bit. Then again I have the S/C and a concrete leg that is attached to the go pedal.

Cyrk,

Couldn't agree more...the loudpedal sucks petrol bigtime w/ s/c.

However, on a calm day on flat ground, (believe me, we have plenty round these here parts) I can sometimes squeeze 19-20 out of her w/ cc set about 70-75.

I've had my VX since '01 and I've been consistently getting about 330 miles per tank using 87 octane gas. It normally takes a little over 300 miles before the gas light comes on steadily. 63K miles and still running strong.

My city/highway driving ratio have varied over these years. I'm convinced that being in Florida (A/C on most of year, no hills whatsoever around here), some minor upgrades (K&N stock filter, synthetic oil all around) and an average driving style have contributed to the acceptable (by VX standards) gas mileage I'm enjoying.

One thing to keep in mind is that mpg will be effected by the elevation you live at, this is commonly forgotten. My Axiom has an onboard info center that tells me i get 17.5 avg mpg with a very heavy foot and my 22s. I did notice a solid 1.5-2 avg mpg increase with my intake kit, and another .5-1mpg with my exhaust. Even with the way i drive which is very agressivly i still get decent milage. Remember that my Axiom is quite a bit heavier than the VX but has the ecact same drive train. The biggest factors to good mpg are clean air filter, regular oil changes with quality stuff, and good gas. I have found the last one to be a big factor in my area, if you get the cheapest gas you can find from the "U pump it"you will get a noticable amount less mpg than with a quality gas such as Shell or Texaco.

I noticed that I get about 290 miles to the tank (310 corrected for Nittos) in the winter, but can squeeze 310 (332) out in the summer. I live in northern VA, so the differences are noticable, but certainly not what I would call extreme.

Colder, denser air = more oxygen content per given volumer = more aggresive combustion?

My Yakima rack with full-sized spare costs me about 20 miles per tank. Interestingly enough, my rack WITHOUT the tire has the same penalty.

I maybe able to add to this. I am a former owner of a VX (and will be again in the near future as $550/month wasn't doing it for me )

I now drive an 81 Olds Cutlas with 30K original miles (bought it with 17k)

NOW, over the past 18months I've also noticed that I am getting like 15MPG and this is after 3 tune ups.

I decided to do a little investigating. Has anyone ever thought that the gas stations are WATERING DOWN THEIR GAS???!?!?!?!?!?!

I can ONLY drive my car on 93 octane and anything lower causes EXTREME ENGINE PING. This has only started to happen and is MUCH MORE NOTICEABLE in a carborated engine.

I asked the dude over at the local Valvoline and he didn't DENY this is happening, just isn't in a position to start pointing fingers.

(ps. STOP HATING ON THAT VX. There are plenty of us out there that would LOVE to be back in theirs )

I don't know about water, but they have been busted before for altering the electronic in the meters and I think they are doing it again! Three times I've gotten reciepts for more than the capacity of the tank and I didn't push it in.

Ron

Colder air is denser so yea better for combustion but because it is denser it is worse for aerodynamics. The tradeoff isn't the eaull so I don't know which one wins.

I get 300-375 depending on driving style-
