alright. I want to switch to an extended drain on my 98 maxima(vq3000 engine). It's got 73k right now. I just past 3750 miles on the last oil change. I'm wondering if I should do amsoil flush or auto rx before switching. been running castrol gtx.

Even if the engine is relatively clean Auto-Rx is still worth while! It clean all the componets that oil touch's includeing you seals. It will recondition them with out harming them in any way. Their is no solvent in Auto-Rx. Most problems associted with ageing and millage in a car usualy relate to seal failure in some way valve stem seals, cam seals,rear main, front main, oil pickup o-ring, valve cover, oil pan, a tiny seal in a tensioner leaking down etc. THe other great think about auto-rx is that it will clean the ring pack of your pistons some and the oil pick-up screen and tube. Most peoples pick up screens are starting to get enough build up from years of use by 100,000-120,000 to reduce flow by 10%-30%. Auto-Rx will break down sludge and help the filter trap it if their is any in the engine. IF you have any seals that have started to dry out and harden Auto-Rx can help reverse this.
