#8 of 17 2006 Buick Rendezvous mileage by dill

Oct 25, 2006 (6:31 am)

I have calculated 26.7 miles a gallon for my 3.5 litre V6 Rendezvous engine a couple times. Average around town and highway driving I get about 20.5 miles a gallon. I have a FWD w/ traction control Rendezvous, WITHOUT the AWD weight many other Rendezvous suffer from.
 
I think under the circumstances I've been very pleased by the mileage considering it is a hair over 4000lbs.

I have a 2004 Rendezvous, with no problems till I changed the air filter. Fuel Mileage went from 26 to 15 mpg. Put in a second filter in hopes of maybe a bad one with no improvement. Any ideas would be appreciated.

I think it might be something that happend as a coincidence with air filter replacement and poor mileage. It,(the air filter) should have improved mileage, not hurt it like you claim it has.
 
I'd get the Rendezvous down to the local Buick dealer and have them run a scan test diagnostic tool on it to check for any problems.

I live in North East Ohio and I believe they start using winter fuel additives around the end of October. My wife's 06 Corolla S was averaging 30+ since she bought it in May.
However since the end of October her mileage has dropped to about 27 or 28 mpg. Nothing in her driving habits has changed. We still fill up at the same place. Still use 87 Octane and the car seems to run and idle the same. Just the difference in the mpg. I was told the reason for the winter fuel additives is to prevent fuel line freeze up. The gas itself wont freeze but the condensation in the lines could freeze and cause the car to stop running. I believe they remove the additives around the end of March or early April

This vehicle is like having gas station near by all times.You never know hom much more you need to go before filling up again.It burns so much gas. I cried everytime I have to goto fillit up,cause I know in a few days I'll be back the station.I wish the car will just burn up and collect on the insurance and get a new vehicle.

#14 of 17 Buick Rendezvous - 27.3 MPG !!! by motobaz

2003 CX V6, 72K on the clock. We were averaging 27.3 mpg on Interstate 5 from Sacramento heading south, full load, kids dogs and luggage, AC on all the time. I set the cruise at 65. Got home to San Luis Obispo and did some town driving and still averaged out at 25 mpg for the tank. We have the Driver Info Feature which tells you your average mpg on the dash display, a nice feature. That's pretty decent for an SUV. Makes me wonder when I see some of these ads for some of the latest cars and they're bragging about getting 28 mpg.

If wondering...
 
FWD = Front Wheel Drive (only its front wheels can spin)
AWD = All Wheel Drive (all 4 wheels can spin).
 
TCS (sometimes called TC) = Traction Control or Traction Control System means that if its special "wheel sensors" computer senses 1 wheel is spinning `too much`, it automatically applies brakes to that specific "spinning" wheel. Thus, forcing its opposite drive wheel to spin - instead of allowing its single spinning wheel to continue to spin. TCS exists on either FWD (Front Wheel Drive) or RWD (Rear Wheel Drive) vehicles. When TCS exists on all 4 wheels, its called Stability Track system. And yes, TCS on the front wheels and Stability Track across entire vehicle exists on the newer technology vehicles - like my wife's new 2009 mini-van.
 
If wondering, my wife has an older technology 2003 FWD RDV (her "in town" run-about vehicle) that only has TSC on its Front Wheels. When one front wheel spins too much, that single wheel speed is forced to slowed down, thus forcing the other wheel to take more traction. From a white board perspective, vision TCS as Traction Balance System - because it balances 'drive power' delivery to the other wheel(s) - that have better traction then its single spinning wheel.
 
Being a lighter weight 2003 FWD RDV (compared to more steel parts in its heavier weight AWD version), my wife's vehicle also gets good MPGs. Not as good as some better wind dynamic 3.4L vehicles (like a mini-van with 3.4L engine) but it gets much better MPGs then an AWD RDV (with 3.4L engine).

Hope this helps...
