I found a local Coastal that sells 100 octane gas for 5.99/gal. Even though
it's awfully expensive I decided to give it a shot. This past summer I pretty
much alternated between 93 octane and the 100 octane - in other words, when I
was down to 1/2 a tank I'd fill up with either the 93 or the 100, depending on
what I had filled up with the last time.
I didn't notice any particular improvement in the performance of the car,
so I am wondering if there was any benefit to using the 100 octane, or did I
just waste my money? When I bought the car four years ago I had the points
replaced with electronic ignition. I put very few miles on the car each year. I
do get it up to highway speeds fairly frequently when I do use it. I also use a
lead substitute every other tankful.
Thoughts, comments, suggestions?
Thanks
