I've got a 2013 roadster that was originally running 10 W 40 oil castrol
I'm now running 10 W 50 oil in the machine and although running well -doesn't seem to have the same grunt as before.
Does running at a heavier weight oil do any long-term damage to the engine as I'd like to revert back to the 10 W 40 and re-gain the horses lost.
