I had the same question when i was using 10W40 and wanted a fully synthetic one -Motul's 300V 10W40(**** , there is no other 100% synthetic 10W40 in europe.Amsoil, red line do you copy???,we are waiting for you!!) so i asked motul about it.
The answer i got was something like .. they are using an obsolate approval in the label just to have something there because racing designed oils don't get bought for their approvals
" Dear Mr. Kariotis,
nice to hear from you again; thank you for your inquiry and for your interest in our products. Attached you will find detailed information regarding your request.
The 300V series was designed only for racing application and therefore no need for actual approvals. You can use it without any risk in your car . But if you are driving under heavy stressed conditions you have to drain the oil earlier. Because the manufaturer says: 15.000 km or once per year for this car when it runs under normal operating conditions.
If you are only looking for an approved product you can take:
MOTUL 6100 SYNERGIE 10W40, but this is not a fully synthetic one.
I hope these information helps you further.
Best regards,
MOTUL Deutschland GmbH
