Where did you hear such a thing like that ???? Not with Delphi's fuel injectors that are in GM vehicles. If you car is set to run on regular it might not be best to run premium all the time in it. Some GM, cars are set up to run on premium but regular is okay but they might not achieve max hp.

Right, if you car is set to run on Premium you should run it, although running on regular will have the ECU dial back your timing and dial back performance, but likely won't injure the car. If your car is set to run on regular you are wasting your money and probably seeing worse milage and performance from higher octane fuel.

in here: G8 production may come here based on demand.
"It is highly likely that as we move to higher volumes for the global rear-drive architecture, we will begin to produce" in North America, said GM Vice Chairman Bob Lutz. "Importing from Australia at this point is a transitional phase. It permitted us to get the car quickly and for a minimum of investment."
I hope they hit the demand.
What I like:
The G8 is 2.1 inches shorter than the Grand Prix, but its wheelbase is 4.3 inches longer, and the vehicle is 3.2 inches wider.
So, no more ridiculous overhangs and a car that may actually have as much working space as the exterior implies? All good in my book, and a heck of a step forward for the General!
Know what I hate?
Waiting...

Well dad said run premium every 10 fill ups to flush the injectors out. My uncle runs 89 mid grade in his pick-ups that require 87. He says he's able to gain about 1 mpg extra. GM's engines you are correct won't gain much power if it's set up to run on regular 87' octane. I however always ran premium in my 02' Cadillac Seville STS and it was fine to run on 87' octane.

Yeah when I'm doing towing in my Armada I throw in a tank or 2 of 93. More important than the octane is where you get it. High volume, newer stations you are going to get better fuel than lower volume older stations.

Hmm, well interestingly unless your car is tuned for higher octane, you actually get WORSE performance from a higher octane fuel. The higher the octane the less actual power you get from each explosion.
Got to disagree on that one.
I ran the car on the lower grade, 91 here, which is what the car is supposedly tuned for 4 about 3 years.
Then I started using 95.
2 tanks through the car and the increase in power and economy are terrific.
Have been using the 95 for about 2 years now and the car has never been better.
It runs so much smoother and has heaps of grunt on tap.
I'll never go back to 91.

In your case, your ECU must be tuned to run on the 95 then, or learned to run on the 95. Similarly, here in the states the Armada is the same truck as the QX56 except the QX56 requires Premium and the Armada only requires 87, a msg board did a test and dynoed both vehicles then reset the ECUs and ran 1000 miles of the opposite fuel in them. After that they re-dynoed them and the Armada had the HP/Torque curves of the QX56 and visa versa. The Q get's about 10hp and 10lbs torque more than the Armada.

Yeah I agree.....I try to also buy top tier-1 fuel from places like Shell and Phillips.
