When you are dealing with CVT (new gen CVT) you need to be cautious.
You can't really say oil is oil, all lubricate, right? With a specific CVT, the manufacturer adds special additives to match clutch or friction materials.
Different trans fluids should not be mixed. For example, Honda transmission fluid made for their accord regular 4-speed auto trans has a warning not to put it in CVT trans.
Another example... go to domestic brands, Ford Type-F cannot be mixed with GM's Dextron ATF. Both are slushbox automatics.
Each has different additives to work with their clutch or friction materials within the trans. Using with the wrong additive can/could cause slippage premature wear.
When Castrol Amsoil starts to make Honda approved CVT transmission fluid that may work, but even then there are older type CVT and newer more advanced CVTs that don't share the same fluid.
In our Civic's and Accords the designation HCF-2 is specific to the latest CVTs.
A name brand, HCF-2 application fluid, is all you need. I'm using Castrol to drain and fill every 2nd or 3rd oil change. It's readily available and usually inexpensive.
There's no need to stick with typically expensive Honda HCF-2 fluid.
I get a kick out of members saying they'll stick with Honda-labelled HCF-2 during the warranty period...apparently for fear than a cvt failure won't be covered if a non-Honda branded HCF-2 fluid is used. Not the case--manufacturers can't product-tie.
