Kraig Hermes & his crew took good care of my 2003 Chevy Duramax with an oil change & engine purge in about a hour and a half. The price was about what Al Serra would charge but it was much more comprehensive . First they drained my old oil, then filled with new oil & filter and added the engine purge. Ran the engine for 30 minutes, drained the oil and filled with my Mobil One Turbo Diesel Oil & Filter. This extra step of engine purge into clean oil and then draining would not have been done at Al Serra Chevrolet and the price was almost the same. I feel more confident with this process and thank Kraig & his crew for the fine work they performed.
