Can. Remove the whole plastic scope, fit sponge at the joints before refitting the plastic scope again.
Potenza very quiet when new. But u must also take into account that he's using 215/45/17, which is actually quite thin compared to stock tyres. The thinner the tyres are, they're bound to be noisier.
Economy not good lah.. Backside also he sell..

SIEN AH!!!

Yes.
If it is still very dark brown (almost black) BUT still transparent looking, still ok but if its black and practically non transparent, its best to start planning for oil change. If waited too long, it might start to become honeylike..
Normally if change at 5K, it will rarely hit this level unless its an old engine with lots of deposits inside. However if exceed 5K, better check constantly. Note that this relates to contaminant suspension that can form sludge. Addictives will still start to wear out after 5K in general.
Only exception should be true FS or those extended mileage FS (specifically designed for extra mileage, more longer lasting addictives).
hmm....actually i am damaging my engine coz my petronas syntium i normally changed at around 7k-8k interval. @@ no money. but actually i dun feel the loss of power. i just feel rougher engine.
