I was just curious what you guys are using for fuel in your SS/TC. I know it "recommends" premium, but Im thinking of probably using Plus.....maybe regular, but I dont think Ill actually go that low. I think the only really draw back is you wont get optimal performance, I dont think it will do any damage though. Im just trying to avoid having to put Premium in another car seeing I already have to in the Vette .

 

Does the 1980 vette have alot of motor work done or is it stock? I would spend the extra 2 buck a fillup and go with 93 if it was my car ... hell i don't use the AC in my car half the time cause it robs HP lol.

 

Premium!!!

 

dude its like 5 dollars extra a tank, it says premium, but hey what do the car makers know


and for the people who say yea youll be fine, the computer compensates, if you cant afford the gas you cant afford the car.

 

For what it's worth, it's 20 cents more a gallon usually. Thats not more than $3 for a dry tank, so a regular "E line" fillup would be an extra $2...

But hey, if you have a better use for two bucks, knock yourself out (figuratively speaking)...

 

u have a turbo,, u put in premium no less.

 

Are you shitting me?!

For premium fuel, don't forget that there is no sensor to "detect" lower grade fuel, there is only a sensor to detect knock. Knocking is BAD. In a pinch you can use 87, but using it on a regular basis means you will likely be hitting knock every time you get hard on the throttle, and then the knock sensor will trigger the timing to be pulled back. This means that every time the knock sensor pulls timing that some knock had to have occurred already for it to detect it. Is it going to blow up? no, but its definitely not helpful to the long term health of the engine. I mean for chrissake, you spent the money on a brand new car and you aren't willing to protect your investment...


Calculate your additional cost per year...it is going to be a $200 difference at most.

 

mmmmmmmmhmmmmmmmmmm

 

I use Sunoco 94, unless it doesn't have 94, then it's 93. If it's not Sunoco, I will use a similar rep gas Co.

 

I use 91 or 93

 

Ok here we go, i have looked through some info and the tech 2 data on my car, you are allowed to use any grade of fuel, but you won't get max performance, the ECM reads the fuel volatility level which can be low-premium, medium-plus, high-regular, it is totally up to you. I use 92 cause i want max performance

 

Actually GM doesnt say it NEEDS premium, they "recommend" it. According to them plus is fine but they say it MAY "decrease acceleration times slightly." Hell according to GM you can use 87(not that I would), all they warn is that (like with any high performance car) you may hear some knocking. And who the **** said I couldnt afford it? I was just curious because there is no need in spending the extra cash if its not necessary. I know how different grades will affect the engine, the reason I asked was because Im not familiar with turbo cars, Ive always been N/A. Thanks for your awesome advice though. And by the way the according to GM the computer does compensate...but hey what do they know?

I completely agree, I was just curious to get other opinions. Im not using less than 91, and most of the time Ill probably be using 93.

 

It compensates by knocking first, then retarding timing.

93 only for my car

 

yeah what everyone else says.....Octane 91,92,94 etc. is the fuels resistance to detonation/explosion and you don't want the mixture to explode before the piston has reached the top of the combustion chamber....otherwise known as knock because is explodes and knocks the piston ie: (VERY NOT good!)

....knock is even more prone in turbo engine because they run hotter....hence the use of the intercooler.....

GET PREMIUM!! or risk the short/long term consequences.....

 

Hell Im with you man. Try 87. The GM guys told me that same thing. You can use 87 but it could ..."could"... make a knock. If you can save cash do it! I will pit 89 in my car when I get it before putting 91. IF it knocks then I will put 91 in. This will be my first turbo car too so we will see. I just hate it when people say ..." you payed bla bla bla for the car if you cant afford the gas you cant afford the car". That is BULL ****! Sorry if some of us are trying to save some cash and not throw it out the window like some people are. We all got the car being that we could afford it.

 

knock knock...who's there??? ohh its ur engine hope you have money

 

You shouldnt use anything less then 91, I never use anything less then 93. You bought a car with forced induction and you expect not to pay alot for gas?

 

When i bought my 08 ss when ever they filled it up the guy put regular unleaded in the tank and it made a weird nosie so i drove till i was on e and put 93 and every since its been fine dont go the cheap way it will mess your car up

 

*****sigh*****

 

ahahaha - good one.

 

Use 91+, 2 dollars extra a week might save your fatass a heart attack if you cant buy an extra 2 double cheese burger from Micky D's.... stop being so stingy.

 

just use 93

 

Thanks man, that was very helpful. This is the reason I asked the question, because like I said Im not very familiar with turbos. Thanks for the info!

 

If you were really trying to save money, you would have gotten a base model or an LT instead of the LNF. Like others have said, you're not going to save much money by using reg of premium. At a station in my area, reg is $4.05 while 93 is $4.27. The difference is under $3.

 

Premium FTW
