Do you guys think that Rotella non synthetic is better?

 

Both Honda and Yamaha oils are now API SJ, and no longer SG. This means a downgrade in the add pack, I imagine to keep the price compeititve.......but nobody seems to know for sure. I no longer use Honda's oils, not even as break-in oil.

If you must run an inexpensive oil, I suggest Maxima Premium (a petroleum oil), which I have found for as little at ~$3.50 a liter. Maxima has the best add pack in the business, so at least you know you are getting that.........
