In short, the answer is yes.
Having your engine flushed regularly, say once a year, helps to keep the inside of your engine cleaner. Why is this important? Keeping your engine clean helps to keep it running at peak efficiency meaning better protection, faster circulation, smoother performance and longer engine life. As well, your new oil stays cleaner longer!
It’s not cool to put clean oil into a dirty engine. An engine flush dissolves and removes any sludge, varnish and deposits in the engine that will drain away when you change the oil.
Using a safe petroleum based and solvent free engine flush is the best and will not cause leaks, plug ports, galleys or screens.
If your doing an engine flush at home, be aware NOT to use any kerosene based flushes as they can do much damage to your engine.
