5w 40 is correct.
Many people will recommend going for 5w30 and see it as am 'upgrade', however I would recommend staying with the 5w40
Among other reasons.. I recommend staying on 5w40 and not changing to 5w30 as this would be counter intuitive to provide the correct protection - on a simple basis as an engine ages/wears gaps increase rather than decrease and so any change in oil in terms of protection would be better served by increasing viscosity rather than decreasing as would be the case with 5w30. (or sticking with original spec)
The other thing to consider when people provide advice is what do they actually mean by better performance? this may come down to what your objectives are...
* a lower viscosity oil may provide better performance in terms on drag on the engine, so this would relate to power and engine performance.
* while based on what the main objective of the oil - ie to protect, then stick with the 5w40.
(although not really a major concern between 5w 40 and 5w30, oil pump rates and other concerns should be considered if making significant changes to viscosity used).
Yep, it’s just Castrol Edge Titanium.

With regular 6 month oil changes, good quality semi synthetic would likely be perfectly fine, as the main drawback would be degredation over time, but with 6 monthly changes ithis is not really an issue. (even at 12 months is not a notable issue)
However it is clear than synthetic oils do offer better protection over a wider operating window and so synthetic oils are the better option. (but do look for good quality so its a true synthetic) id prefer a longer 9 month change with better quality oil than 6 monthly with a cheaper oil if cost is a concern..
