I have summarized and compared the specs of the three Lambdas from the '2008 Online Order/Reference Guides'. It looks as if the Enclave is marginally longer/wider/heavier with minutely less interior volume.

Yup, I've noticed that too. The curvier body panels most likely contribute to the slight variations in exterior dimensions. The "quiet tuning" materials (i.e. extra sound deadening, laminated glass, triple door seals, etc) most likely add the extra weight. And the slightly less interior volume is surely because of the sloping roofline compared to its sisters.

There is actually a mistake with the gas mileage figures. Edmunds (and other sites) put up the 2007 estimates from the Acadia/Outlook on the 2008 Enclave. All 2008 vehicles will ship with the new "lower" EPA figures (Federal law) which for the Enclave are probably going to be 16/22 (AWD) and 16/24 (FWD) based on the new 2008 ratings for Acadia/Outlook. In NJ this means we probably (don't know for sure yet) have to pay the .4% (yes, "point 4") gaz guzzler/luxury tax (see http://www.state.nj.us/mvc/Vehicle/luxurytaxsurcharge.htm) ??? My NJ dealer is unclear if this will be the case. The question is if NJ will be adjusting their MPG avg point slightly lower due to the EPA now rating cars lower (true MPG).
This tax is not a lot of money ($160 on $40K) but is kind of silly on a car like this.


Refer to http://www.fueleconomy.gov/feg/ratings2008.shtml regarding the new regulations

Shouldn't it be $1600? 4% of 40,000. Thats a lot! (for me at least)

I think monsters stated it as 0.4%, not 4% - so the $160 is correct.

I've been trying to determine the fuel grade requirement for the Enclave but can't find that info anywhere including this forum.

Can anyone shed light on that for me? With all the discussion about fuel economy, the difference in actual cost between regular and premium fuels (like the Lexus requires) can be a significant factor in the purchase decision.

Thanks,

87 grade fuel

Thanks. Based on my understanding of fuel grades, that would be regular.

Regular - 87 octane
Super Unleaded - 89 octane
Premium - 91 octane

BTW, some have mentioned sluggishness. Has anyone tried a higher grade to see if performance improved?

Thanks again for the info.

Based on what's been said, the "sluggishness" sounds as if it is a transmission issue, not a problem with the engine, although 275 horses moving 5000 pounds does not a rocket make. With regard to fuel, while higher octane gas allows certain high performance engines to run without knocking, etc., I doubt that putting a higher octane mixture in an engine designed to run on regular will improve its performance.

I'd agree. In fact, in some cases (probably not for a new Enclave) with older engines that have lost some compression a higher grade fuel can be "too" difficult for the engine to burn, leaving unburnt fuel in the exhaust and leading to lower performance, fuel economy, emission problems, valve buildup, exhaust damage, etc. Of course, a new Enclave isn't going to suffer from compression so low that even 93 won't burn completely, but the idea is that you should run the fuel in an engine that it was designed for.

You should check out "TOP TIER FUELS" (TTF) Regular Grade
GM And other auto manufacturers us this when testing the vehicles for emissions and fuel economy.
You can find it at http://www.toptiergas.com/deposit_control.html
I am using Shell In my Enclave.
Wet on a 243 mile trip to Jacksonville, averaged 26.7 MPG with some Town Driving. Wasn't broke in yet
so I had to hold the speed down and not use Cruise.
On the way home I cruised at 60-70MPH and averaged 26.4 MPG

Was that FWD or AWD? Either way, that isn't bad at all for a vehicle with more room than a Yukon or Sequoia...

You're right, I should update the specs to the new 2008 EPA standards. I simply copied what was already out there, and I'm aware the EPA changed their methods for review and pretty every car on the market gets downgraded since their new tests take into account things like AC usage and road gradients. I'll be sure to get to this soon. Thanks for the reminder!

Does anyone know whether or not the Enclave can accept the Ethanol gasoline at 105 octane?
No, Enclave cannot accept Ethanol fuel (E85). I believe some stations (Getty/Lukoil) sell E10 (10% ethanol) fuel which is supposidly safe to use in any car.
If you go by the manual, GM wants you to only run TopTier fuel http://www.toptiergas.com/ in the enclave

sorry to bring back old threds but i think your premium is wrong, isnt it 93 octane for premo.

also there is next to know difference in preformance with premium fuel.

Nitrogen in the tires? Color me ??? I am just a girl, you know!

Also, I was not happy to see that my beloved Costco gasoline was not on that list - they save me $.10-$.15 a gal!!!!
