Motul 300v Engine oil - revisited. Important.
As most of you (probably know) I am an AVID Motul 300V oil fan. Been using it for years and years on every bike from racers to Goldwings.
However, my dealer has informed me to now use 10w50 instead of the 10w40 (which is also authorized by Triumph).
The 40 may be too thin and eventually cause a very slow leak as it seeps through certain parts and sensors. No major damage can occur, but it could be an irritating issue to rectify.
Read into this as you will, but i do trust the mechanic and I have now switched to 10w50 Castrol power 1 racing. I would recommend anyone using 10w40 300V oil to change to 10w50, especially as we enter spring/summer.

Reason: Castrol, not Mobil
