Sunoco fuel at Indy

This info is about 10-15 years old. I believe that it still holds true. Sunoco Blue and Purple are blended gasolines. VP equivalents are specifically designed race fuels. This why VP is more expensive. It even smells different. It was designed for the turbo and supercharged "gasoline" powered engines many years ago( outlaw cars etc.). It then trickled down to a variety of race fuels. Sunoco to the best of my knowledge is fortified pump 260 that was available in the 60's and early 70's. This is why it burns well in older iron. The two are hard to compare, sort a like big box store spring water and Fiji water. When you have a system that works it is hard to change it. If you test and tune or dyno with a specific fuel you do get different results. Tuning to a new fuel can be difficult when cars are run on the edge. When fuel or gasoline is tested in a lab they NEVER put it in plastic containers. It screws up their testing. It is sold in metal containers not plastic. Storing one type of fuel in a plastic container for many months can taint a new manufacturers fuel. There is a difference. As far as bulk sales, you always have to consider who is delivering it and how professional are their standards .
