Marvel Mystery Oil as a motor flush? We try it out!
One of the downfalls of buying a used car from a dealership is that you have no idea what the maintenance history is. This is especially true of oil changes. Did they use good oil, the right oil or did they change it on time? I've used Marvel Mystery Oil as a motor flush every time I buy a new car and I've had awesome results. The wife just purchased a 2017 Nissan Rogue so I decided to use this as a test vehicle for this process.
