Always like to get an analysis done to see how things are going with the engine. With a little over 35000 miles (63000 kms.) on it, the engine appears to be in great shape according to blackstone lab results. Peace of mind for sure.
@me32 I just recently purchased this Boss. Believe previous owner was using the Motorcraft 5W-50 and had a Mobil 1 extended life oil filter on it. Car uses a stock air filter. When I changed the oil, I used 5W-50 and the Motorcraft FL-500s filter. We'll see how it performs after my next oil analysis.
