> My 2000 Audi TT is supposed to run 95 octane gas (owners manual doesn't mention top tier). Around me, 95 octane is not very common (don't recall ever seeing it).
Your owner's manual probably refers to the Research octane number, which is what is commonly used in Europe. The octane number on US and Canadian pumps is an average of the Research and Motor octane numbers, and is quite a bit less than the Research number. I think 95 Research octane would be around 90 octane at the pump.
Top Tier didn't exist when your Audi was produced. Audi now recommends the use of Top Tier gasoline. Note that Top Tier is independent of octane; for a fuel brand to be Top Tier, it must meet the Top Tier requirements for all of its grades of gasoline, not just premium.
> When I had it out west, there were places I could only get 89 or 91 octane.
Gasoline suppliers in high elevation states like Colorado and New Mexico are allowed to slightly reduce their octane ratings, since (in theory) you don't need as high of octane at high elevations. I think all of the state must be over 3,000 feet to qualify. I always try to gas up in Nebraska just before I enter Colorado for that reason.
