Because they can.yipching said:Why do different states have varying octane ratings of their premium fuels? Is it a state law thing?
I live in upstate NY, and our high-grade gasoline is 93 octane, sith some Sunocos offering 94...
If you put in 87 Octane, just make sure the engine is not knocking. There will be a slight degredation in performance from the lower octane as the computer will have to retard timing a little to compensate. However, it should retard the timing and there should not be any knocking. BUT, if it does knock, you definately will want to go to a higher grade.Tuxedo Mask said:So what will happen if you use 87 octane in the GTO?? Gas over here in Vegas is very expensive. $2.30 for premium. Does using 87 octane with additive good for the engine?
I am not too sure how much the additive cost. I am just asking because it seems here in Vegas that gas prices are rising almost at an hourly rate. Regular unleaded is at 2.20!!!!! i put in about 15 bucks yesterday and it only filled up about 1/4 tank. So if i put in 87 for the time being i will be okay?Neo-GTO said:If you put in 87 Octane, just make sure the engine is not knocking.

I see no real problem with using 87 and an additive, but is it really that much cheaper than buying the higher grade right at the station? (serious question, I have no idea how much those octane booster additives cost).
Your engine should run ok on 87 Octane, but pay close attention to it and make sure it doesn't begin to knock. If it doesn't knock, you are ok. If it begins to knock, get octane booster and dump it in. It shouldn't knock because the engine should be able to compensate.Tuxedo Mask said:I am not too sure how much the additive cost.

Look premium is about .20 a gallon more if you were to buy 1,000 gallons of gas a year good for at worst 15,000 miles or 21,000 miles if you drive thrifty by coasting to red lights ect it will cost you $200.00 extra a year about $17 a month extra. My fiancee gets about 18 mi /gal in her 6 speed avg, I think she can do better if she would up shift to 5th faster. my vette averages 20-21 mpg overall, at 80 mph on a 600 mile round trip to vegas I get 29.8 mpg.Tuxedo Mask said:Well, looks like it's gonna have to be peanut butter and jelly sandwiches from now. i didnt realize that using premium is a must with this car. i am going to give this car a couple of months...if it takes too much money from me.....i will trade in the car.
Oh trust me, i love the car. Right from starting the ignition, you can tell the car has some power. But right now, i guess it depends on the freakin price of oil per barrel. Gas is going way high and it seems like no end in sight. i was thinking of trading it in for a G6....ONLY IF I HAD TO!TORRIDONE said:Look premium is about .20 a gallon more if you were to buy 1,000 gallons of gas a year good for at worst 15,000 miles or 21,000 miles if you drive thrifty by coasting to red lights ect it will cost you $200.00 extra a year about $17 a month extra.

Also think about the trade in hit you would take! Keep the car enjoy! Don't do it.

Wow, $2.39 for premium gasoline in 2004!!! I wish. 93 Sunoco Octane is costing me over $3. Some interesting old posts.So what will happen if you use 87 octane in the GTO?? Gas over here in Vegas is very expensive. $2.30 for premium. Does using 87 octane with additive good for the engine?
