Extended oil drain intervals: good or bad?
Manufacturers of many modern passenger car and light truck engines recommend extended oil drain intervals; 12,000 to 15,000 miles is not uncommon. It’s almost impossible for these engines to operate for such extended intervals without forming engine-destroying sludge in the lubricating system. The solution to this problem is to use Flushing Oil Concentrate at every oil change - a very small price compared to the costs of engine damage due to inadequate lubrication caused by sludge and other contaminants in the engine oil.

"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!"
