What is high velocity oil flushing?

High Velocity Oil Flushing is an industry best practice for meeting oil system cleanliness specifications. Using auxiliary pumps and jumpers to bypass system restrictions of a lubricating system, the process rapidly removes contaminants from fluid systems.

When should you flush engine oil?

Exceeding a service interval one time is usually no reason to perform an engine flush (unless the interval has been exceeded significantly). It is only if you haven't changed oil on time several times in a row (which is extremely damaging to you engine), that you can take this procedure into consideration.
