Oil change service near Saint Johns, FL

I had an oil and filter change at this place while I was visiting from out of state for the winter. After paying for the service, I checked the oil level and saw that the oil was black! I have been changing oil(I'm a mechanic) for fourty years and I know the oil was never changed on the visit, All they did was spin a new filter on and top off the oil. When I complained the mgr. quickly refunded my money. I know what oil should look like on the dipstick since I change it myself and the oil was not changed! To be sure, I sent the oil out for an analysis at a cost of 30 bucks and the analysis indicated high level of contaminants not consistant with new oil. The owner Laurie was a nasty person when I spoke to her and continued to defend her workers. THIS PLACE IS A RIPOFF. BEWARE!!!!!!!!!!!

Their diagnosis was wrong. Now they say they did not give me a diagnosis. I wouldn't complain if that were true. I paid GMC $166 for labor and I paid $225 for the control module. Now I have to also pay GMC $166 for a diagnostic test because All Pro gave me the wrong diagnosis. I told GMC not to do the diagnostic test because it was done by All Pro. Now I know better. Never trust All Pro Automotive! Not only did they diagnose it wrong and point out the part that needs replacing when I asked what it was, now they deny ever diagnosing it and say it was beyond their ability to properly diagnose. So I just paid over $550 for nothing. Don't trust their word. They are liars.
