Gas Brands

6spd

BP/Amoco, Chevron/Texaco, Shell, Sunoco, and Mobil are perhaps the big 5 of the major gasoline brands. All of them have quality fuel, given proper quality control is place (and this is very crucial). Lower octane is not as good for an engine as premium, for the most part. Of course this is just a general statement. Some cars are tuned to run on lower octane, but inherently suffer shorter engine life than cars tuned for higher octane. This is because of the cleaner combustion and the subsequent carbon build-up. Using too high of an octane can scorch the inside of the combustion chamber. What you choose to use is up to you and for most people, they will fill up with whatever/whoever is cheapest. For the Z, just use premium fuel, whether it be 91 or 93/94, and get it from a quality station like the aforementioned companies.

That pretty much sums it up.
