Are engine flushes a good idea?
A good engine flush can help loosen deposits and dissolve sludge, helping return your engine to like-new condition. However, in old engines with high miles, sludge may be the only barrier keeping oil from seeping through worn or cracked seals. Removing the sludge exposes the seals for what they really are – junk.
How do I know if I need an engine flush?

They will bond together in the oil passages and stick, potentially causing a blockage and reducing oil flow and pressure.

An engine flush can help you go longer between oil changes, especially if the maintenance on the car hasn't been perfect.
Will engine flush clean piston rings?
It can make the rings move better, but it won't actually clean them. An engine flush basically circulates oil through the engine to get rid of gunk and buildup. This can actually get some of the gunk off the piston rings to keep them loose, and might improve performance temporarily, but it's not a long-term fix.
How do you flush old engine oil?

Is synthetic oil better for older engines?
Myth: Full synthetic oil is not good for high mileage cars or older vehicles. The myth is rooted in the idea that synthetic oil is “slipperier”—lower in viscosity, or not as compatible with seals and will therefore leak or leak more in places conventional oil might not. Again, completely untrue.
Does ATF clean engines?
ATF is not made to clean sludge from engines. Instead, it's best to use a dedicated engine flush. AMSOIL Engine & Transmission Flush helps to remove sludge and deposits from engines and transmissions.
