I don't need a decal advertising what brand of air filter I am running, and I don't need a sponsor either for air filters.
Or you can be like my buddy an x top fuel racer.
A big company wanted them to use a certain oil. They were going to give them big bucks to put their oil in there engine and put their name on their car.
Big problem. Their oil was junk and my buddy did not want to use it.
Solution:
My buddy took the deal and got the money. They then proceeded to pour the new oil out of the bottles and throw it away and refill those bottles with an oil that worked for their needs. The fans saw the label on the bottles and the oil going into their engines and never knew the difference.
Everybody won and made money on this deal. Win, win, win!
