Wynn’s Professional Formula Engine Flush is a pre-oil change flush that internally cleans vital engine parts, removing harmful deposits, sludge & varnish that impede oil flow. Wynn’s Engine Flush is specifically designed to gently dissolve & remove internal engine contaminants by suspending them in a high level of dispersants. The Wynn’s Professional Formula Engine Flush ensures maximum drainage of the contaminants with the old used oil, thereby minimising new oil contamination.
