Hell you did Scotty. You are in this bunch who write about the oil that is there but:
you cannot see it you cannot smell it you cannot hear it you cannot feel it.
And just when it fits your purpose you claim it is making your engine knock. Try putting it in the fuel can next time and not the cooling system. That's if you can see it, feel it, smell it or find it.
There was no BP gas in the states 20 years ago it was Amoco you moron. So please quit making things up, BP has the best gas you can buy and thats a fact. Do a google search on best gasoline and you will see BP is rated #1
