Who knew? I’d always bring my vehicle to the dealership. Bringing my vehicle in for an oil change at TGK, I was impressed with all of the additional details they were able to give me in all sorts of areas of my vehicle. While the dealership gave me a check list of items they checked, I was impressed to see the additional detail that TGK provided besides just the check marks. Great reference material for future maintenance… as well as estimates. I found this extremely helpful. Peace of mind.
