Tiger 955i (2006) - Recommended Engine Oil

Hi, I am about to service my Tiger 995i (2006 model year) and would welcome any recommendations /feedback regarding which engine oil to use.

 

10/40 semi synthetic immune...same bike, same year.
Any decent quality brand.

 

'immune'?...er, ' in mine.'

 

Just switched to Westway 10/40 fully synth in my '95 Trident 900. The bike seems to love it - runs smoothly with excellent clutch and gearbox action. At £24.99 for 5 litres I love it as well. There is a 'Westway Lubricants' thread hereabouts which may be helpful to you.
