Diane-It's a 2006 BMWx3. Is regular ok for that do you think? I don't drive much/spend much on gas, but it'd be great not to have to pay the premium.I always feel like a patsy at the premium pump.

Do you have the owners manual??? It should tell you what octane you should be using...

High Octane for most cars do nothing but waste your money. Its really not necessary.

My Sadie requires 93. But she's worth it. I just try to combine trips n stuff.

This is in the area of what I do. Check your owners manual. It will tell you. Don't call the dealership, they might not know. Or go to the BMW website.

If it says use 93 or higher it is because the engine was designed to provide the best performance AND mileage with higher octane gas.

If it says use regular, go ahead and use it. Higher octane does nothing for a car not designed for it and it may even decrease mileage

Not quite. BenzEne is the simplest aromatic hydrocarbon molecule.
" An aromatic hydrocarbon (abbreviated as AH) or arene [1] (or sometimes aryl hydrocarbon)[2] is a hydrocarbon with a conjugated cyclic molecular structure that is much more stable than the hypothetical localized structure. The term 'aromatic' was assigned before the physical mechanism determining aromaticity was discovered, and was derived from the fact that many of the compounds have a sweet scent. The configuration of six carbon atoms in aromatic compounds is known as a benzene ring, after the simplest possible such hydrocarbon, benzene. Aromatic hydrocarbons can be monocyclic or polycyclic." http://en.wikipedia.org/wiki/Aromatic_hydrocarbon (Mirrison and Boyd was the organic textbook I used at Uni)

"Gasoline (North America) or petrol (outside North America) is a petroleum-derived liquid mixture which is primarily used as a fuel in internal combustion engines. It is also used as a solvent, mainly known for its ability to dilute paints.

It consists mostly of aliphatic hydrocarbons obtained by the fractional distillation of petroleum, enhanced with iso-octane or the aromatic hydrocarbons toluene and benzene to increase its octane rating. Small quantities of various additives are common, for purposes such as tuning engine performance or reducing harmful exhaust emissions."
(also from Wikipedia)

HK, keeping the record straight.

I thought they referred to the fuel as benzine in Germany, so I included it. Maybe in other places it means something different.

Glad to see our resident chemist is back.

You are right, I am wrong. Benzin is the German neuter noun meaning gasoline. I should have remembered that. In my defense, the last time I was in Germany (2003), I took trains, trams, subways, and busses everywhere. Not much of a defense, I admit.

What Term said.
I drive a 2009 Lincoln MKS and it runs fine on "regular" gas.
They say it gets another 10 horsepower if you use "premium" but it doesn't run any better on "premium." I get 275 horsepower out of it in "regular" gas and that's more than I need.
Some engines do need "premium" fuel like high output engines in Corvettes and other high compression engines but most will get along just fine using "regular" fuel.
