So what is the point of changing? Despite that, aftermarket fluids have been used in vehicles for a long time. It has always been my practice to use the exact aftermarket product made by the specific automobile manufacturer unless I can find the same product made by the OEM.īy exact, I mean Z1 ATF, not a fluid that can be used for multiple purposes. It is more cost-effective to produce a formulation that can be mixed or applied to a broad range of applications produced by aftermarket companies. Final WordsĪs an example, Honda/Acura manufactures its own in-house brand, the Z1, that is designed for a specific application. As far as I know, there are no failure reports of one running Maxlife. It is important to remember that the Odyssey probably has the worst track record for transmission longevity, and Maxlife performs exceptionally well in these vehicles. Honda isn’t going to approve any of them. ATF Maxlife is “suitable for Z-1 use” according to its specifications. Honda Odyssey owners with Z-1 spec’d Odysseys use Valvoline Maxlife ATF. You probably don’t have to change your engine oil and filter as often as you change your oil. The process of adding fluid usually takes longer than draining it. Make sure you do it after you’ve driven through all the gears as well.

Make sure the ATF dipstick is at the right level using the ATF dipstick. The funnel, a wrench of the right size, the location, a container to catch the old ATF, etc. It is also important to know where the drain plug is located. Add the new ATF in the right place and in the right way. DW-1 is probably available for purchase and could be brought to the garage, but is it really necessary? The Honda dealer is much more expensive than an independent garage because I don’t do this kind of work myself. No matter how good or bad a substitution might be, it’s not the same as the original. DW1 can still be used instead of Z1 for draining and filling at the next recommended interval. However, they haven’t been tested and don’t meet the specifications.Īll Honda transmissions that are not CVTs can be upgraded to DW-1, which is compatible with Z1 and replaces it. Your car’s oil maker recommends the other fluids. Honda’s own fluid is the only fluid that meets Honda’s specs. No bad experiences have been reported, or at least no more than would be expected with Z1. However, users who switch seem to like it better than any other alternative. I would recommend Amsoil if you are dead set against using the Z-1. Substitute Transmission Fluid That Meets Honda ATF-Z1 Again, Honda has officially replaced ATF-Z1 with ATF-DW1. It is compatible with Z-1 and DW-1, so there is no need to mix it with the old ATF left in the truck. Valvoline MaxLife Dex/Merc ATF has received great reviews from owners. Several people have posted on other (non-Honda) forums about using Castrol ATF with no problems. Sticking with OEM is often better than using Valvoline or Castrol.Ĭompared to the Honda DW-1, they are a few dollars cheaper per liter. It is recommended that you use DW-1 if your vehicle originally used Z1. The ATF DW-1 fluid has replaced the ATF Z1 fluid.
