Is there any benifits from using off the shelf engine flush with an oilchange?

If so which product is best?

 

no unless they have a way to flush it all the way through the oil coolers .

if you cange the oil often there is never a reason for a flush.

Engine flush is for old engines. We don't have moving parts like Pistons so we don't have alot of metal and carbon to burn off.

That stuff may damage your apex seals.

Got a 1965 with a ton of miles? Use it on that beast.
