I had an oil change at Walmart . After driving 160 miles my car died on the side of the road . I changed the spark plugs and checked the oil . Two spark plugs were wet with oil and their respective cylinders were full of oil . The oil level was too high . It was way above the hatch marks . I drove the car home and the car had very little power , the engine was running horribly and smoke was billowing out the tailpipe . Walmart denied responsibility . I watched the video of the oil change and it showed what looked like a proper oil change , however the camera was too far away to verify the correct amount of oil was put in . And the view of the oil being taken out was completely blocked . Assuming a certified mechanic verifies damage due to too much oil , will I have a case ?
