Testimonials

  • “I had bad valve guides from the overheat and worn rings. Lots of smoke even with 10W-40 until warm, and always on acceleration. I flushed the engine twice – once with a flush and then again with diesel, and then added your product. The smoking stopped.”

    Roy B.

  • "We use Entek Smokeless Oil in our racecar and not only did it stop the smoke it also felt like the power increased. Great product!"
