Just had a look at the Motul site/s and see that the 300v line has updated the series with "double esters." check out the French site 300v Motorsport range
Would be great to learn from somebody what the theorie and practice say about impact of weight on valve train wear.quote:

Which grade would give lower valve train wear ?
In my limited experience, it is a combination of valve train weight, valve spring pressures, materials used, surface finish and hardness.quote:

These graphs give just a general idea/trend, but data itself is similar to an average patients' temperature in the hospital. No doubts that 0W-20 and 20W-60 will give different wear.quote:

According to the graphs in my link above the new 300v is tested as having less than half the valvetrain wear of the old 300v.
