This is Motul's last stop on the way to 300V. Very high, relatively speaking, ester content, it is more like 300V than it is the 5-40 Xcess product just below it. I've wondered what the differences really are compared to the 300V. Though it probably won't tell us much I'm looking forward to the UOA to see the rudimentary data. Thank you for testing this. Your willingness to test so many oils is much appreciated.
