Can M1 ATF be used in lieu of Honda Z1 ATF? I really prefer M1 since it is full synthetic and is much cheaper than Z1 from the dealership. I am not near any distributer to pick them up to save on shipping cost. Currently, I am looking at almost $9 per quart of Z1 while M1 ATF can be had for $26 for 5 quarts.
Also, is using Z1 really that necessary? I mean, fluid is fluid and as long as it is changed frequently, it should matter, right? I am aware of the added protection some fluid has but is there a "do or die" rule that one must used ATF or fluid from specific automaker if longevity is desired. I know use M1 5W20 full synthetic instead of Honda 5W20. Can the same logic applies to ATF?
By the way, I just changed ATF and filter for my 1992 Corolla. All I can say is Toyota knows what they're doing in AT design. The filter was cheese to replace and very cheap (only 10 bucks for the whole kit which includes a rubber gasket seal.) I really hope Honda go back to have a serviceable filter. Why can't automaker make their ATF filter the same as engine oil filter, which can be change without taking things apart. For AT, heat and impurity are the two biggest killer. If I was in-charge of design, I would make it much more robust than they are now. Then again, I'll put mechanics out of jobs since the AT would last 500k miles without any problem.
