Pennzoil/Quaker State Multi-Vehicle ATF users

[thecritic]

Is anyone using the Pennzoil or Quaker State Multi-Vehicle ATF in their transmission? If so, please state the year/make/model of your car, as well as the shift quality.

I'm interested in using this fluid in a Honda Z-1 application, as this fluid is a composed of a Group III basestock opposed to the Honda ATF Z-1's Grp I or II basestock, which should allow the Multi-Vehicle ATF to have better oxidation resistance and a longer service life. Jiffy Lube and many independent shops use the Pennzoil or Quaker State Multi-Vehicle ATF, so if you've had a transmission flush done by Jiffy Lube recently, they would've used the Multi-Vehicle ATF.

The reason why I considering to deviate from the factory, OEM Honda ATF Z-1 is because of the many issues I've had with the fluid turning brown or black, within 15 or 20,000 miles in the newer, post-recall 5-speed Honda/Acura automatic transmissions. (2004+) IMO, the Honda fluid is not up to par and is depleted very rapidly and I'm hoping that the Multi-Vehicle fluid will bring a longer service life.

I'd throw a cooler in there if there's any doubt. A particular brand or rating is not going to be that dramatic in difference.

Orney, not true. A particular rating (i.e. Mercon V, ATF+4, SP-III, T-IV, and the new/upcoming Dex VI, as well as many others) contains a specific friction modifier in order for the transmission to work properly. The fluid must also pass tests for oxidation control, shearing, service life, anti-foam properties, and many other tests. Thus, it is important to use the correct type of fluid for the application (i.e. a DexVI fluid in a DexVI app)

As far as Honda ATF Z-1 goes, the problem that Honda ATF Z-1 seems to suffer is not heat, but more a durability problem with their fluid as it seems to turn dark quite quickly. The Honda ATF Z-1 is actually a GrpI/II petroleum fluid, unlike most fluids which are often a blend in order to pass the tests for the specific spec. If one does stick with the Genuine Honda ATF Z-1, it'd be wise to do a drain/refill with 3qts of Honda ATF Z-1 every 15K to keep the additive pack refreshed.

wrong fluid will let the clutch packs slip or not let go. ever heard a LSD chatter from someone not using a friction modifier? same thing but alot more clutch packs to screw up.
