Will Shell pay me for water in their gasoline?

I had just filled my cars gas tank with regular unleaded gasoline at a Shell Station, just off the interstate. within two minutes on the road, my cars engine began bogging down. i could pump the gas pedal and it ran smoother for a minute or two and then it repeated the same procedure. i stopped by Auto Zone and bought a can of Heet moisture remover and poured it in my cars gas tank. this was of no help, so i took my car to a mechanic friend of mine. he installed another can of moisture remover and installed a new fuel filter. engine ran fine after this. my total bill was $215.97. i paid the bill. Question: is Shell responsible for reimbursing me or am i just wasting my time?
