Okay, I would say why I "like" rather than "prefer" the Honda MTF-III Ultra because I have never tried any other brand besides the one that the previous owner of my car used. Before using it, there was this crunching noise when I shift gears especially from 2nd to 3rd. And since it was also time to change my gear oil, I surveyed around and asked here for opinions. Many suggested this brand. So, I got it. Since I changed the gear oil, shifting is smoother and I love it. I don't know how to express it in words but it's just easier and smoother and nicer to shift gears, being shifting up or down. Besides that, I also noticed that the crunching noise I had due to the gear synchro was gone. I know this is only temporary but at least till then I don't have to hear the crunching sound.
