Motul rep on internet:
------
Myth: 300V is only used for racing
Truth:
Although Motul's 300V lineup is engineered for use on the track and is tailored for ultimate engine performance and protection under extreme conditions, *it is also suitable for use on the street.*
*What matters more is the viscosity*.

Use the right grade (5w40 Gen 3 manual)
Its a question of cost vs use case. Not suitability.
I agree its not worth the extra cost if you *don't already have it*, 7100 is better vfm for the road.
Ester based oils like 300v are the ones with the highest film strength they are ultimate in terms of protection. If you're seeing 12k rpm or more, regularly, its ideal. If you're usually not extending the engine beyond 10k then again vfm wise 7100 would do.
3-6000miles *road miles* have been done plenty of times, on 300v, according to anecdotal internet reviews which have shown no ill effects. How many cover more miles in a season, without a change?
It turns black because it has additives designed to clean the engine. So using and flushing it often is great for cleaning but clearly harder on the wallet. Colour change is not a gauge of if an oil needs changing. Smell and viscosity compared to unused would be better but not perfect.
I have read the additives in the oil are shorter lived than in 7100, but thats it, nothing beyond that statement. If its the ones that do cleaning then its not a surprise. 7100 doesn't have them, so it seems logical to presume so. Cleaning additives have nothing to do with film strength.
300v doesn't breakdown from shearing forces it survives the brutality of racing. So its likely only 'done' when its overloaded with contaminate. Overly rich fueling can end the life of oil early.
Don't bother reading American forums on engine oil (read one guy thinks it only last 300 miles).they have all been had by marketing. Can't separate 1960's mineral oil practice from 2020's Synthetic.
I'll buy your 300v if you don't want it though its got to be less than what Opie would charge
