Greetings Berryman Team I am interested on purchasing one of your products and i have some questions on how to use it. The product that i am interested in is the Berryman B-12 Motor Tune Up for Gas and Diesel. As i can see on the bottle and based on what i read on your website i can use it in the gas tank,diesel tank and i can add it into the oil. My question concerns the quantitity that i should use based on where i want to add it. To be more specific i own a Mini Cooper S and the fuel tank can hold up to 50 liters of gasoline.How many oz can i pour into the tank?Can i use your product prior to an oil change as a "motor flush" product and how many oz should i use there? I also own a Yamaha XT moto how may oz should i use in the gas tank there last but not least how many oz could i use in a diesel engine of a small business van that i own? Thanks in Advance George
