Deffinetly consult your owners manual on the correct octane gas you should be using..But if you are still into the break in period you might want to wait and see cause a few people have noticed an increase in mileage after the break in period was done....I noticed that in my SE....

Not really....
In most states I would have to agree. But I'm stationed in Louisiana Barksdale Air Force Base, the prices are not that bad here.:alien:

The dealer told me that the car will take regular. (87 octane) What gas you put in should be based on the car compression ratio. Higher octanes are for higher compression ratios. If your octane is too low the fuel will ignite prematurely and you get knocking. I found the compression ratio is 9.5:1 for the Spec V through Sport Compact Car Magazine. I'd say you can go on regular for about 8-9:1 compression ratios. 10 and higher you probably want to use premium. Consider the Sepc V is a non aspirated engine, I don't think it needs premium. My manual says 91 octane. I use 89 and my car runs fine. I have yet to calculate fuel economy.

gas
Manual says 91 octane. I am sure that the care will run ok on 89 if you want to save a few cents. Also, elevation has something to do with it. For every 2500 feet above sea level, supposedly you can drop 1 octane level.
As far as efficiency... I have not been very happy with my Spec V. I was expecting to get 26 - 28 city, and 31 - 34 highway. I have been getting about 25 city, and 28 highway. I did get over 30 one time. I am sure I have a bit of a heavy foot (If I didn't there would be no point in owning a SER), so I could probably improve a bit just by backing off the accelerator. I would use the higher quality gas even if we weren't instructed too. It is cleaner and I think better for the engine. Some engines get detonation and run poorly on too high octane, but not our cars.

I use 91 octane cause thats the best we have in Cali. I was getting better gas mileage and now it's just horrible. I get like 20 miles to the gallon. I am really dissapointed. I takes $20 each fill up. It's really hurting my check book.

I calculate my gas milage every tank. I am averaging 26 mpg. I also use my ac everyday, and am constantly flooring it! I got it up to 28 mpg once, and that was after a trip to Orance county and back, and I set the cc to 75 both ways.
The small gas tank doesn't help us either.
