Calling all 06/07 SS owners
I have a new 07 SS on order. I have seen many conflicting areas as to what type of fuel (Regular or Premium) should be used.
In the 2006 Monte brochure it states that the 5.3 V8 runs on regular. In "Spec" out sheets on the car it indicates premium. I seem to remember that somewhere I heard that yes, you can run regular with no problem, but premium should be used for maximum performance. Will there be any problems is you use regular grade (87 Octane) all the time????
What are you using? Have you tried both grades, and if so, do you notice any differences?
What's your feelings?
Are there any GM techs out there following this board that can give us the straight goods on this?

In my 06' manual it clearly states for the 5.3L to use premium fuel of 91 octane or higher. Any LSX engine should use premium fuel. If you can afford a Monte Carlo SS, you should be able to afford premium fuel.

Your comment on being able to afford the premium fuel strikes me as somewhat sarcastic. I don't have any problem with the damn cost of the gas, I am asking the question because there is a discrepancy in what various GM literature says.
I have a 2006 brochure and on page 9, where they explain the technological features, it says, and I quote:
"The 5.3L V8 Displacement on Demand (DOD) engine on the Monte Carlo SS features pent-roof combustion chambers, flat-top pistons and a composite intake manifold that all help the engine generate outstanding power without having to use premium gasoline."
Who knows, maybe the specs changed since the brochure was printed. If you are reading from your owners manual, I would assume it should be correct.
No offence

Yeah in the fuel section is does say to use premium, not being sarcastic at all! A car as nice as this should use premium without hesitation. I dont know why GM prints conflicting information. Vette with LS1/2/6/7 all recommend premium. Camaro With LS1, recommend premium. Even my Cobalt SS Supercharged requires premium. I would assume for sure the LS4 does as well.

None of the monte carlo engines require premium.

In my 06 manual, it says Premium should be used, however, if necessary you can use regular in a pinch. I will scan this page and post it here as proof... Unless for some reason the Canadian Manual is different then American.
Going to sleep so I will do it tomorrow...
3.5, 3.9 no
5.3L Yes

unleaded gasoline with a posted octane rating of 91 or higher. You may also use regular unleaded gasoline rated at 87 octane or
higher, but your vehicle's acceleration may be slightly reduced, and you may notice a slight audible knocking noise, commonly
referred to as spark knock. If the octane is less than 87, you may notice a heavy knocking noise when you drive. If this occurs,
use a gasoline rated at 87 octane or higher as soon as possible. Otherwise, you might damage your engine. If you are using gasoline
rated at 87 octane or higher and you hear heavy knocking, your engine needs service".
So there you have it. You can make your choice. I know which grade I'm going to use. 91 or higher, no spark knocking for me.

Recommended and required are two totally different things. Required in a GTP with supercharged engine yes. In a trans am NO. Maybe recommended for maximum performance in a Trans Am but it's never been required. Wrong info 07montessgirl!!!!
