#2501 of 2927 Gas mileage on my 05 Montana SV6
Mar 01, 2006 (2:44 pm)
I bought my 2005 Montana SV6 12 months ago and have had no problems at all.
I know some find this MPG to be impossible and I wouldn't have believe it if someone tole me:
I drive a 2005 Pontiac Montana SV6 and the estimates for it are 18 city, 25 highway. I drove from Tulsa to Houston during Xmas, 530 miles, on a single tank and got 29.9 mile/gallon according to the digital readout. (Had 1/4 tank left too) When I filled up (I always top it off to get an accurate read)the actual REAL mpg was 28.5 I drove 70-75mph about 90% of the 8 hour trip. Stopped only twice to go to the bathroom. BUT, I accelerated slowly, tried not to use my brakes, etc. I also filled my tires to 38lbs before leaving Tulsa.
I was actually playing a game where I was trying to get the best possible mpg and watching the digital MPG readout go up and down according to speed, stops, etc.
So now I am sure that they don't use the best possible conditions and speed to get the estimated mpg.
But most young people (I am 49) accelerate and use their brakes way too often and this lowers your mileage more than you realize.

That's awesome gas mileage! Did you have some extra reindeer pulling you?

How long had you had your van when the sliding door flew open?
I've heard of this problem with other new vans too. I think it was the Odyssey.
#2504 of 2927 3.9L V6 VS. 3.5L V6 difference for a soccer mom

Could someone please explain to me whether I should purchase the 3.9L engine option on a GM van. I am a mom of four active boys with a lot of in town driving.
I don't know what the practical difference is between the engine types.
Also, how much wear and tear is it on the new Buick or Saturn vans to add the trailer/touring package and pull a boy scout cargo trailer? Can it pull a trailer? I thought it's not a good idea for v6 to pull a trailer.

As a rule I would always go with the bigger engine. Get the tow package and you will be fine. I like the Buick over the Saturn as it comes with auto load leveling rear. The tow package comes with the heavy duty alternator ( you won't have any of the electrical issues), Transmission cooler, Tow harness, hitch. Rated at 3500 lbs.

the 3.9ltr is rated for 240HP vs. the 3.5ltr with 200HP. But the downside is your CANNOT get the AWD with the 3.9ltr (FWD ONLY). So if you wanted the AWD you would not be able to have the larger engine. Plus the larger engine has more torque, which will be better for your towing needs. As for the diffenece with Gas mileage, it doesn't look any worse for wear. The mileage looks about 1-2 mpg less than the 3.5ltr (fwd) and the same for the 3.5ltr with AWD.

I have the 3.9L V6 on our new Buick Terazza and I absolutely love it. The vehicle accelerates beautifully, nice and smooth on the highway and there is definitely extra pep available for pulling trailers or a whole van full of people - I would recommend it, especially since I didnt pay an extra dime for it here in Canada - just request it on the van when they find you the one you want. The mileage differential seems to be zero by the way.

Appreciate your feedback!!
And your feelings are the same as mine. However, I think with the cases of faulty vehicles that we read about here goes to prove that GM does make a few Lemons!! And these lemons...they (GM) need to take responsiblity for!!
My family and our business have owned about 10 GM vehicles in the last 8 years (we like to trade the company vehicles every few years). I know that my van is NOT GM quality!! I just need GM to accept the responibility and let me out of this lemon headache!
I came to this forum to look for advice on how to handle my Lemon case and I have received it.
