Since the MC21 came out in 1990 Lubricants and Oil technology has come on in leaps and bounds since then. Its fair to say that there would be a big difference in oils in the last 30 years. Do you think this means that we could be over looking a far more beneficial oil for our transmissions? Honda recommended what they had to chose from back in the day. Can we confidently say that Honda would still recommend this oil if they re looked at it?
