## Description

Pre oil change treatment that helps maintain the cleanliness and efficient operation of your engine. Suitable for use in petrol vehicles.

Review: Perfect end of service additive - A perfect blend to your engine just before your car's service. Just pour it to the engine bay and that's it. It does the job. Flushes and cleanses the difficult to reach part or slug and carbon deposits. I could feel a little better in the car pick up. And that's because all of the dirt or deposits are removed. The provided quantity is suitable upto 1.5 cc engine car.
Review: Fine product!! - Used it for the first time. I think it worked well. Even topped it with an engine oil I used for the first time. Vibrations have reduced. Seems alright but too early to tell.
