People spend way too much time worring about saving 10-15 cents on gas.
 
18 months ago premium 93 gas was 2.89 gallon...now it's 4.09 You'll get better performace and mileage if you use 91 or better on Audi's, especially on a Turbo motor.
 
Keeping proper tire pressure and controling your driving habits will save you just as muh if not more than worring about 87/89 vs 91 octane gas.

Got an A4 brochure from dealer by willbuyan09

I went to the closest dealer yesterday and he had a brochure available. Not the flimsy card, but the book like brochure. He said they should have cars in late September-but these are the ones Audi decided to send them. The ones they have on order will arrive in Oct.
 
I took a picture of the brochure and got in an 08 A6. The dash is almost the same.
 
I think I am leaning toward the Avant to have the extra cargo room. It has the 2.0 T engine, which is the one I prefer. Better mileage. The salesman told me that I should be able to get close to 30mpg hiway.

"Shippo. Quick, tell John McBush! "
 
I wish...I'd certainly vote for Bush again in 2008. Anyway, don't you think this is off topic?

A4 Swap by mcmuney

I'm thinking of trading in my 2005.5 A4 3.2 CVT Quattro for a 2009 2.0 CVT Quattro. I'm doing this for 2 reasons: 1) I need a new car every 2-3 years, I get that itch and 2) Better mileage.
 
I'm currently getting about 22MPG lifetime average, which isn't bad, but I think I can get 30+ with a 2.0. I'm also thinking of leasing this time around.
 
Has anyone switched from a V6 to a V4? I'm wondering if there's a significant difference. I'm used to the power of the V6.

Just a couple of things. The '09 A4 2.0 Quattro comes with the 6-spd tiptronic transmission. The CVT is only for the front wheel drive version. There won't be that much difference from your V6 to the new 2.0TFSI engine in the '09. Although the new 2.0 T engine has 211 hp, the torque has increased from 211 to 258 pound-feet of torque which is really the key to accessing the full performance of your engine. I've read that the new 2.0T has great acceleration, but you should let your test drive speak for itself.
 
Enjoy!

If you are acquiring an Audi, BMW or Mercedes, etc. by markcincinnati

. . .you will note they have been engineered to use Premium gas. They have also been programmed to be able to retard the spark sufficiently to reduce pre-ignition (PING) which does, over time, do damage.
 
The impact of doing this does not totally eliminate the damage, but for practical purposes, you probably can get away with it -- besides the warranty will be long over before the damage would be paid for by Audi (et al.)
 
Mileage and performance are impacted by using 87 octane, when the engine has been engineered for maximum performance and mileage on 91 or 93 octane.
 
If you poke around you will find both opinion pieces and "objective" pieces that explain reasons to use the "recommended" octane. Often, at the same time, you will find articles that claim no advantage is gained by using premium in a car engineered for regular. The opposite is not the case, however.
 
For the heck of it, I tried regular in my Audi 3.2 ('05 A6). The car didn't start "normally," it seemed as if it were being driven with the emergency brake slightly engaged causing a drag on the accelerative capability. When I reached a 1/2 tank, I put premium in and couldn't wait for my old A6 to return.
 
Wondering, I did the same thing to my wife's car (a 3.0si engined) BMW X3. She thought the car needed servicing (I didn't tell her about the gas until after the fact.)
 
I guess if one were to start from day one using regular, well you might think the way the car performed was "as designed." Pity.
 
These cars are often over $40K (my new A4 will be north of $47K) and why would I not use the recommended fuel under the false assumption of saving money is difficult to imagine.
 
Audis are designed to use premium gas. If this is a show stopper for you, buy something else.
 
Using regular in one of these cars, especially the forced induction models is an exercise in a "false economy."
