IMHO a whole year might be a little long for that oil. Here's why:
Motul 300V is "racing engine oil developed for Factory Teams". I'd be surprised to find out there's marketing hype for a racing engine oil that recommends leaving it in your engine for 12 months.
For that there's Motul 7100, which is their ester synthetic oil with an additive package that's suitable for street use and normal oil change intervals. There are hints in the data sheets.
Motul 300V recommendations:
For optimum engine and gearbox performance, avoid mixing with other synthetic or mineral lubricants.
Oil change: according to your own use.
Motul 7100 recommendations:
Drain interval: according to manufacturers’ recommendations and tune to your own use.
Can be mixed with synthetic or mineral lubricants.
