I did a search but coul not get an answer so hopefully no one throws that one at me.

I got my 2005 but the sticker nor the dealership could give me an answer of fuel type for the 2005. I assume premium based on the Hp but my 2004 SSR took regular.

So...to the 2005 owners, Regular or Premium? :confused :confused :confused :thumbs

Ifd you put in anything but premium, the engine will run with it, BUT the pcm will retard the timing, so you lose power. If you buy a 40k vehicke with a 390hp Corvette engine, why are you screwing around with cheap fuel?

octane

I believe it tells you what octane is needed in the brochure. The 2004 needs 89 and the 2005 neets a higher one.

octane

Maybe I mean 87 for the 2004, whatever the low grade gas is. I just looked in the 2004 brochure and didn't see it. I know I read it somewhere. The 2005 not only cost more, but it cost more to run also.

Premium

Haven't tried anything but premium. When we bought the car they told us to use premium since it was a high performance engine. They said it would still run on a lower grade but it needs the high grade for performance.

The owner's manual states 91 octane or better, it will run on lesser but poorly....Don't chance it

:thumbs Sure enough, 91 says the manual. I had an Acura Legend that took 91 and I put 89 in it one occasion. I got a horrible knocking engine noise with that tank of gas, I do not want to have that happen again. Thaks for the replies, you'd think that the dealership would know. I was shocked that my 2004 SSR took 89 when I got it!

This is what my fuel gauge states................

Buffy,

Can I get one of those for me. I need it when it comes to putting fuel in the truck. But would it work better if it told how much from full not empty. :)

HA HA HA

Is there a Difference.

I know that most of the gas stations have 3 different choices on each pump. But, I have a real hard time believing that there truly are 3 difference grades in those pumps. Someone out there, convince me that I am wrong.

Steve,

True story, I let my friend take my Cadillac STS to Georgia to visit some of our mutual friends one time. The STS required premium fuel only. I forgot to mention this point to them so it is completely my fault (they could have read the placard on the fuel door but!!!). When they got back home with the car it is spitting, coughing, and pinging to beat the band. I took it immediately to the local Cadillac dealer and asked them to fix it under warranty. They drove it off and in about five minutes the mechanic and service manager asked me to walk back to where my car was sitting next to a computer. They pointed at the screen and said "Sir, why have you been running 87 octane in this car?", of course I said "I would never". The mechanic looked me straight into my face nad said, "this computer aint lying"!

Therefore, after a burning off the old gas, one full tank of premium, the car was back to its usaual high performance self. From that day on, I BELIEVE!

Regards,

Rob

Tell you what, it sure makes a difference which gas you use after you've used a Diablo Predator to "performance tune" your computer.

Steve, I too kind of was sceptical on this, but it made me a believer too.

and once again, make sure you do NOT use Methanol (ethanol) based fuel in the '05. It's in the manual...
