Re: Gasoline Prices Below 99 Cents/Litre By Christmas

Oil, filters, tune up, coolant flush.

It's just a thirsty engine. GM's 3.9 is known as a guzzler.

That actually isn't too bad for a 3.9L 6. To call it a "guzzler" isn't really fitting.

The Corvette may also have a better tuned displacement on demand system or whatever marketing term GM is calling it now.

When other people are managing to use half the fuel for the same distance, it seems excessive.

I vow every time I buy a car that I'm going to get something small to save money on fuel, but ultimately find that I need a mid-sized car to be comfortable. I then need a decent engine to move that car. I'm a slave to my automobile.

I told my buddy I'm going to buy a Vette just to save money. lol

I've heard that too. Did the G6 not come with a 3.6? My previous car (Saturn Aura) had one and it wasn't too bad. My current car (Pontiac G8) has a 3.6 but in north-south configuration not east-west. It's a bit of a pig in the city but on the highway it's decent.

Mine is a 2006. It was the only G6 available with a manual transmission, which is the main reason I got this combo as I really wanted to learn stick. It's fun to drive.

2007 is when the GTP's started including the 3.6. The GT "Sport" package got the old GTP 3.9L with F40 6speed manual. By 2008 the 3.9L wasn't available anymore.

The Impala's had the same engine with active fuel management (displacement on demand). I'm not sure why they didn't pair that configuration with the G6.

Ah, this is why your 3900 is crappy on fuel. The same thing happened with the old V8-fired Grand Prix and Impalas. The Grand Prix had no displacement on demand, while the Impala did. Evidently this is the same deal with the 3900 between the G6 and the Impala.

No idea why GM did it this way, but it wasn't the first time they did it. In the grand scheme of things though, the 3900 *still* isn't bad for an engine that size with all cylinders firing at all times.

the 3.9 is also used in a lot of GM "Minivans" (Pontiac Montana, Chevy Venture, etc) as well as a few other Pontiac, Buick and Chevy products.

»en.wikipedia.org/wiki/GM_High_Va···gine#3.9

there are lots of them out there, and i haven't really heard much in the way of "issues" with them, other than perhaps being a little thirsty.

Mine is exhibiting the typical GM 60 degree V6 gasket leaks. Another guy I know had a head gasket failure three times (I actually blame his mechanic for the subsequent repairs). Otherwise the engines are good.

yea, i think that issue affects several different V6 engines from GM...it is a massive widely known issue, but GM doesn't seem interested in doing anything about it.

Is this the same issue as the 3.1 and 3.4?

To the best of my knowledge, the 3.1 and 3.4 are part of the 3800 family. My mother had a 1996 Grand Prix up until recently with a 3100 under the hood. The 3.5 and 3.9 are newer designs that are related to each other.

Someone can correct me if I'm wrong, though.

Incorrect. The 3800 is a 90 degree v6. The 3.1, 3.4, 3.5 and 3.9 are all 60 degree v6's.

The new Camaro uses a 3.6...it produces 300+ hp and gets decent mileage according to EPA figures...

quote:
»usnews.rankingsandreviews.com/ca···ormance/

The base 2013 Camaro has a 3.6-liter V6 engine that produces 323 horsepower at 6,800 rpm and 278 pound-feet of torque at 4,800 rpm. A six-speed manual transmission is standard on the base 1LS model, while a six-speed automatic is available on 2LS and higher trims. The EPA reports that the 2013 Camaro gets up to 19/30 mpg city/highway, which is about average for a muscle car, but less than rivals like the Mazda Miata and Subaru BRZ.

There is also the 4.3 litre which is like a 350ci with the last two cylinders removed. I believe it is mostly used in rwd cars and trucks...

True, but the 3.6 is what they call a high feature engine. It is physically bigger than the 3.9 I have due to it's overhead cam design.

It would have been nice if they'd used the 3.6 with my car in 2006, but they waited until 2007 to start doing so.

Yeah, those HFEs are built in St. Catharines and Flint. When someone calls from one of the telephones the call display actually says HFE V6 LINE as the name, which I always found rather amusing.

I'm jealous of you sometimes Gone, you live a life I only dream about....I never get cool calls from HFE V6 LINE....only wrong numbers from the same person over and over and over again...and on the call display it definitely doesn't say HFE V6 LINE....I just get ones that say "ONT LOTTERY"....but that's not too exciting.....because I know I'm not winning the lottery...lol...I know that's completely OT for this topic, but to bring it back on topic...

Gas prices down to 124.9 here in the Nickel City...who knows...maybe it will hit 99.9 sometime before Xmas...but it'll have to go down at about 4c/week for that to happen here....and it hasn't been going down at that pace at this point, more like 2c/week...so maybe 115 or so by xmas...

Also, nitzguy is getting a car that's a bit better on gas than his Freestyle....so hopefully that'll help save me some more at the pump.

When you live in St. Catharines at some point everyone in the city is bound to get a call from the HFE V6 Line
