There is a significant body of both scientific and empirical evidence that suggests that using Regular gasoline in a car optimized for Premium (such as an A6) will result in measurably LOWER fuel economy. Said another way (using Mark's example), given that Premium gasoline is between 5% and 6% more expensive than Regular these days, any "savings" gained by buying fuel on the cheap will be eaten up due to having to buy fuel more often for any given number of miles driven.

There used to be an article on Edmunds about using fuel that had an octane rating that differed from what the manufacturer suggested. I couldn't find the link, but to recap the article, using octane that is too high for your engine results in fuel that is not fully used in the combustion process and as a result can damage your emissions system. Using fuel that is too low in octane rating can cause knocking which will damage your cylinder heads. So if you hear your engine knocking, you might want to reconsider the octane. What was said previously about the electronic fuel system compensating for lower octane might be true, but it wasn't discussed in the article.
#6672 of 6921 Gas Mileage

I have an '07 Audi A6 Quattro. I too have wondered about going on the cheap with regular or mid-level. However, I like the extra power of super and the cost savings of regular is offset by the better gas mileage with premium--plus no worries about any engine consequences.
Believe it or not, I'm getting over 24mph with the Audi and it only has 6k miles so far.
Here's what I do. If you drive with some common sense you can get some great gas mileage.
First, I always coast to stops when nearing lights. Saves on the brakes and the hated brake dust buildup.
I don't gun it taking off. I'm past the age (and ego) of racing lights.
Freeway mileage is helped by keeping it under 80. Since I enjoy the car so much, I tend to focus on the smooth ride and great Bose system.
I know its common sense, but check the tire pressure. Remember to do it when the tires are cold. A 10% reduction in pressure robs mileage unnecessarily. Plus it keeps those 18" tires from wearing prematurely.
Finally, I'm no driving prude. I take corners, off and on ramps like a mad man. Love that handling. That's where I get my driving kicks. Fast starts and stops just make no sense anymore.
Hope this helps. 24mph is nothing to sneeze at and I don't believe I'm shortchanging my driving experience.
Just my 2c.
#6674 of 6921 Use Bimmer 5 Series Cost Less than A6's?
Jun 11, 2007 (6:59 pm)
I must be reading this wrong. I stopped in at an Audi dealer over the weekend and liked the looks of an A6. I thought "Gee, given their horrible resale caused by the unintended acceleration/defective coil pack experiences, I should be able to score a current body style A6 with quatro for a lot less than a Bimmer." I fired up my computer and ran some rough numbers for the MY 05. Edmunds has the private party value of an A6 quatro with the 4.2 V8 at 35K and with the 3.2 six it is 28K. Lo and behold, the Bimmer 530 is less money at 31K and the anemic Bimmer 525 still lower at 29K.
I thought Audis had horrible resale and you could pick up a good one on the cheap? I never expected that they were more money than a Bimmer. What gives?
Incidentally, I asked the sales guy six times about Mark from Cincinnat's claim that you could buy an A6 with a stick and each time he said no.

Mark's discussion about a stick in an A6 was for the pre-2004 car.
When purchased new the 2005 Audi A6 4.2 cost a few thousand dollars more than the 2005 BMW 530. So it is not surprising that it costs more used. As far as depreciation, Edmunds claims that the Audi will depreciate $18,195 over 5 years, while the BMW will depreciate $16,824 over the same 5 years. On a percentage basis, the depreciation is about the same.

Thanks for clarifying the stick shift issue.
Conventionnal wisdom would have you believe that a used 5 Series ("The ultimate driving machine") is going to cost more than a Audi A6. Not so, according to Edmunds.

If you were comparing a 545 to a 4.2 the BMW would cost more. But you are comparing a 530 to the 4.2 so the Audi costs more.

The last A6 that could be had with a stick, here, was the C5, and not even the 2004 2.7T could be so ordered. As I recall, it was possible, POSSIBLE, to get an allroad 2.7T with the manual shifter then. Of course the allroad was discontinued since the "CUV" had not yet become as popular.
The allroad is due to come back. Probably won't happen.

Right, a 530i is a little more than a 3.2 Audi. The main point still stands: that Audis do hold their value roughly as well as a Bimmer. This is much to my surprise given their ongoing troubles, so-so dealer facilities, lack of being a "hot" brand among the 30 year olds, etc.
