Knowing that you are in Miami, I am in Ft Lauderdale and I go to a place called VP Racing Fuels on Andrews ave. I fill several 5 gallon containers (he sells the real good ones there for racing) and add about 2 gallons to every tankfull of high test. It works better than any octane boost. I use 112 octane which is $7 a gallon. He sells 103 Octane that you can pump directly into your car (too expensive though), 110 octane, 112 and 116 that can only be pumped into gas containers. It took me several tries to discover the right mix using the minimal amount of the $7 a gallon gas. I found that anything less than 2 gallons to a whole tank of standard high test resulted in engine ping. Since I don't drive the car a huge amount a tank could last me several months. Best Wishes, Russell Housen PS Since you are in Miami let me know what shows you attend, perhaps we can meet at Tower Shoppes one night. What model letter car do you have?
