What justanold replied as far as types is all the basic info that you need, however, let me insert my two cents with some info that you may benefit from.
I am by no stretch of the imagination an expert or authority to be blindly trusted.
However, there are a few things that I know for a certainty and others that I am comfortable with.
One thing that I know for a certainty is this.
ALL gasoline is the same. Each company has their own name for the additives but it is all the same.
There isn't a secret recipe, varied aging process or any basic products that are different. It all comes from crude and the only real difference in crude is that some crude is easier and less costly to refine.
Even if I did not know this, and before I knew this, I was doing some electrical work at a Tenneco oil refinery in Mereau, La, south of New Orleans, in the early 60's.
While there, over a period of 3-4 hours, I saw major oil company trucks coming in and filling up, Texaco, Gulf, Mobil, etc. And to confirm this, there is a Chevron refinery about 60 miles from where I live and they supply gasoline to all of the stations within at least a 100 mile radius.
Now as far as the fluids for your vehicle, they also come from crude, I use Wal-Mart products since they guarantee that whatever they put their company name on is equal to or better than national brands.
One thing that I did hear but do not know for sure is that Quaker State is said to contain a lot of parifin which will cause a wax type sludge build up in your engine.
I hope that my rambling is of some use and help to you.
