A little over a year ago I used Seafoam and Lucas in the Ford Ranger. The engine was making a lot of noise. The gasoline engine sounded more like a diesel engine. After using Seafoam and Lucas, the engine sounded great! But did the fix last? In this video, we take a closer look at the ranger, looking inside the oil pan using a boroscope, checking the oil and filter for contamination, and checking the used oil for film strength. We also take the Ranger on a test drive.
