Gas premium 91 or 93?
 

Hi all,
Audi suggests Q7 take premium 91 gas. But I usually feed my sweet ride with the highest level gas like 93.

I'd like to know what kind of gas do you use for your Q7?

Is it a waste of money if manufacture suggestion is 91? Do you feel any difference between 91 and 93?

Thanks.

I run only Exxon 91 in mine since new, never experimented with anything else.

I love how the average consumer assumes that the higher the octane number, the better the gas...............

I use 93, but only because it's "2" better than 91.

I do use 93, but I don't have to pay for my gas.

i always use the highest octane available.. 91 and 93 has very little to no difference at all.. but if we were talking about gasoline brands than that's different, i always try to use exxon as much as i can.. in the audi i can only feel a slight difference in accelerations while on my old lexus it's a big difference when you accelerate if you use exxon vs let say "sunoco".

If it says 91 is recommended then that is what you should use, any higher is just a waste of money

It helps RTM closely - it says 91 octane content minimum, not exclusively 91.
I do buy 91, 92 or 93 where it is convenient at the moment. When I am at home town, I often gas up at Costco Gas selling very decent 91 grade 25-30 cents cheaper than anyone else in town (using Costco Visa for gas gives additional 4% back).
If I'll have a choice, I'll buy no ethanol gas, because this whole thing about burning food and being environmentally conscious at the same time is a complete baloney, or as Brits'd say bollocks.

I have to go 93, because thats what we mostly get here...87, 89, 93. If I happen to be at a pump with 91 (some sunocos I believe), I'll fill with 91, even though its only 3-4 cents cheaper than 93

I get 93 because at the station closest to my work, it's the cheapest at that octane, and also is the only one that contains no ethanol.

I have never seen 93 here in NM - only 91.
