They messed up my oil change 2 out of 3 times. I always bring my own oil as i use Amsoil Full synthetics oil and oil filter. They come in 946ml bottles and my Mazda 6 requires 4.5L the first oil change they under filled with 3.5L only. Second time was fine. 3rd oil change they overfilled by 700ml. They made a mistake, I called them on it and wanted it fixed as overfilling can cause engine oil frothing and cause damage. They called me crazy and a bad customer and was kicked out.
