What is the proper way to use engine flush? Do I drain the oil first or add the engine flush to the oil?
1. Check to make certain the oil in the crankcase is up to safe level and then warm engine to driving temperature.
2. Immediately before changing oil and filter, add Pyroil Engine Flush to crankcase and allow engine to run at normal idle speed for 5 minutes. Do not drive vehicle or race engine until crankcase has been drained and fresh motor oil installed.
3. Drain crankcase and replace oil filter.
4. Refill crankcase with fresh motor oil.

You don't have to change your oil filter every time you change your oil.: Valvoline recommends changing your oil filter each and every time you change your oil. This eliminates any risk of contaminants trapped by the oil filter, such as dirt, from re-entering the oil.
