Do audis take regular gas

Do the different options at the gas station really matter that much when I’m filling up my Audi? What kind of gas does an Audi A4 take?

Answer provided by

They do, especially when it comes to an Audi A4! An Audi A4 takes premium unleaded gasoline with an octane rating of 91 or higher.

Using fuels other than the recommended kinds for your vehicle could potentially lead to damage to your engine or fuel system.

For more specifications about what kinds of fuel and additives are best for your Audi A4, as well as what kinds to avoid, refer to your owner’s manual.

I have been putting premium gas (93 Octane) in my 2007 A4 2.0T Quattro. But I was told by the Audi salesman that there is no problem in putting regular gas (87 Octane) as the system senses that and adjusts accordingly. The trade-off would be in performance. So I tried the regular gas with half a tank and I did not notice any degradation in performance. Before I try the full tank with regular gas, I wanted to get your opinion regarding this. Are there people who have been using regular gas on their A4s? And if so, what are their impressions with regard to performance and fuel mileage?

I just got my 2006 A4 2.0T Quattro, a pre-owner certified I got a killer deal on. The salesman, like yours said, it is "okay" to put in the cheaper gas, but he said it is more mileage that would suffer. I had a Toyota pickup that would develop knocks with cheap gas and when I put in 91 octane it went away, but the cheaper stuff is tempting at paying $3.91/gal for gas here in the Bay of San Fran.

not only are you going to loose power(performance) you will loose gas mileage.... if you feel the need to use "cheap" gas, trade in your car that requires good gas and get a "cheap" car to put that cheap gas in.....

i don't understand why people buy good cars just to go cheap with them, also why your salesman, who must be an idiot would tell you.... yeh you can put crap in your tank, unless you were on the edge and he told you that to sway you........ then that is your fault and you should of stayed over the edge and bought that honda you wanted

Never use anything lesser than 91 Octane on your A4, or any Audi!

I also wonder why people go and by a luxury car and then they want to put cheap gas, or cheap *** mods on it, That makes not sense. If you don't mind bad gas mileage, loss of power, sputtering, and shortened engine life put in the cheap gas. You can also save moeny but not changing the oil. It is not like the oil isn't still in the engine, why take it out and put in new?

I concur with all the above. In an emergency regularis OK, just use as little as possible. You didn't notice in a half tank because it was either a sufficient mixture to provide the required octane or the ECU had not yet fully adjusted the lambda channels. But as everyone else has already stated, why buy a $35k car then try to save $0.20 a gallon on gas. 16 gallon at $4 per gallon is $64, 16 gallon at $4.20 is $67.20. If the $3.20 saved is required to continue living, I'd still be looking for a different expense tocut the $3 from.
