Anyone running Valvoline Extended Protection ATF in the ZF 8 speed? How's it going? thinking of doing a ppe pan in the spring wondering if it's worth it over the maxlife I'm running now

I’m running HPL Green Cold Climate in a ZF 9 speed and happy with it. Not the same in either case but a data point nonetheless.

I am at 16k miles, so not anywhere near servicing my ZF. I’m looking at the PPE and the Ravenol. Keep us posted whatever you decide to do.
 
I dropped my pan, changed filter, and filled with Valvoline Extended Protection on my gladiator a few hundred miles back at 32,xxx miles. The Mopar/ZF fluid that came out was the consistency of water, at best. Shifts fine after the changeover and temps are normal. I can’t imagine I’ll be going back to the ZF/Mopar fluids.

How long have you been running the HPL? From what I have read, the ZF 9 fluid is a super-low viscosity and the only aftermarket fluid that has been specifically formulated for it is Pentosin.

I would love to not pay the premium for the OEM fluid, but I am hesitant with how sensitive and finicky I have read about the ZF 9 being overall in general.

Thanks! Good to know it works.

About 7,000 miles. Zero issues so far, it shifts great.
 
I ordered Mopar 8/9 speed fluid for mine. I have some maxlife on the shelf, so I could top off with that if 7 quarts doesn’t cover the spill and fill with filter for my 2020 Wrangler.
 
Rock Auto carries the Pentosin for a reasonable price. Which i used in a Honda Passport with no issues. Also recently put the Liquid Moly in our Gr Cherokee from FCP Euro, with their ZF pan, the transmission seems to shift smoother.
 
Not when it's over $30/qt :sneaky:

A gallon of Maxlife is cheaper than a quart of Lifeguard :D
FCP Euro, one and done. I send it back and get store credit. Use pirateship.com for inexpensive return shipping. So my second and all subsequent services only cost me the return shipping. ($20) This includes the fill and drain plugs, gasket, filter kit and o-rings.

I return the differential fluid, fill and drain plugs also.

And you see nothing wrong with returning consumable maintenance items?
