Off-topic slightly, we changed oil suppliers recently and the bottles of universal cvt fluid do not show that it meets the J4 specs but their website shows that it does.... so it gets dumped in hole.
I don't know that I'd still use it thinking that it didn't have the proper amount of herbs and spices specified by the mfg, regardless of how the mfg says it works well in racing applications where drivetrain components are often replaced after a season if not every race.
For some real-world data, do a search for "cheap plastic car" or stevedmc. He used his 5speed Mirage for work and posted most, if not all his service records for the car. It was the highest mileage Mirage on this forum for the longest time.
