Help, I received an oil change and engine flush at a local valvoline and three days later on the interstate with grandbaby the car lunged and i barely made it to the side of the interstate. Once taken to mechanic we had motor dropped and they stated most likely engine flush did damage but really no way to prove. All the oil veins were dry and there was sludge in the oil pan. Motor was locked up. We only have 73,000 miles and oil changed regularly. Valvoline says not responsible. My understanding those oil flushes are suppose to get sludge out. Any advice appreciated. I am to the point I am comtiplating doing a demonstration in front of that business might get response that way. LOL

I realize that you are distraught, BUT, to get any meaningful help in an internet discussion group, you'll be doing yourself a giant favor if you include a little more information such as, the year, make, model, engine size, engine type, (gas, diesel, hybrid, turbo, no turbo) transmission type, (manual, automatic, AWD, FWD, RWD) and any other relevant information <recent maintenance/repair history/modifications, location on the planet> in your initial post.

What prompted you, at 73,000 miles, to have your engine "flushed" in the first place? What type of engine flush was used? Was this done on a special flushing machine, or simply out out a can with the words "miracle XXXXXX" written on it? What type of oil was used after the flush and how far did you drive before your vehicle encountered problems?

I don't mean to be flip, but with the information you've provided so far, the best help you could hope for in this format is a wild guess about what might have happened!
