I read somewhere that the motor oil that Honda recommended in 1990 had additives that are no longer in the oil. Basically that means that the old recommendations are no longer valid. Your best bet is the fluid Honda provides for their new manual transmission cars. I can't remember where I read this information since it was two years ago when I sold my VX, but I changed the transmission fluid and used the Honda fluid. It doesn't take much and one of the weaknesses is the input shaft bearings in the Honda transmissions. If you don't have any problems with your transmission then personally I would use the fluid Honda currently recommends.

I learned this lesson the hard way a long time ago when I changed the fluid in a BMW 2002, only to find out later that BMW used mineral oil in their transmissions at the time. Had to replace all the synchros in the transmission, a $600 mistake in 1975, I'll never forget.
