Fluid advice Nissan RE5R05A

RE5R05A (08 Titan) – Valvoline MaxLife vs OEM Matic S for heavy idle use?

Running a 2008 Nissan Titan with the RE5R05A. Truck sees a lot of idle time (3–4 hours daily for work), plus normal driving.

I know Nissan calls for Matic J/S (now basically Matic S), and I understand the friction characteristics are tuned specifically for that fluid.

My question is more from a builder/rebuilder perspective:

Have you guys seen any measurable difference in wear, clutch life, or valve body behavior running something like Valvoline MaxLife (which claims Matic S compatibility) vs OEM/Idemitsu Type S over the long term?

Not worried about cost—more interested in longevity and heat stability under extended idle conditions.

Would you:

1.	Stick strictly OEM fluid

2.	Run MaxLife and shorten service intervals

3.	Or is there a better fluid option you’ve seen perform well in these units?

Appreciate any real-world teardown observations or failure patterns.
