The AC-21 Engine Oil Flush is formulated to effectively clean, dissolve and remove harmful deposits, sludge build up and varnish before an oil change. Oil deteriorates in quality and performance over its service life which accelerates the build up of contaminants.
Use of AC-21 prior to oil change will see benefits such as improved engine compression, longer oil life, reduced oil consumption, increased engine efficiency and less oil oxidization. AC-21 promotes suspension of impurities to remove them safely from the system and provides lubrication protection when cleaning.
The AC-21 product does not contain high aromatic solvents which can deteriorate the existing oils lubricity making it safe to run if driven after adding the product. AC-21 contains anti friction additives to ensure that this product is effective yet safe to use. As engines run hotter due to advances in technology an oil flush prior to changing is vital.
