If you are seeing black residue in the oil after a short time then yes, the oil is braking down. All synthetics are not created equal, some are only 10%

If you are seeing black residue in the oil after a short time then yes, the oil is braking down. All synthetics are not created equal, some are only 10% synthetic yet still call themselves synthetic.
I would stick to the oils that people have tested successfully for now. |
