Amazing Product

"I tried the Flushing Oil Concentrate on my 2016 F250 6.7 with 180k miles. I've never seen a clean dipstick on that engine as diesels are well known for dirty oil. You have to do two oil changes but after carefully following the directions I saw a oil color I've only ever seen on brand new engines. I even thought that I didn't have enough oil in the engine, it wasn't until I realized the oil was clear that I had to pick my jaw up off the floor. If you want to clean your engine to make it last, this is the product for you!"
