I used this oil 4 times, I will not recommend using it more than 1800 KM in Bangladesh 14mm T spanner used for draining oil. 8mm T spanner used for opening oil filter cover.
Yes I have used, gear shifting is very smooth. Vibration will happen if your clutch is worn, otherwise no vibration. Heating issue will be only if you stand idle for too long, it doesn't depend on the engine oil.
I have ridden maximum of 1780 KM with this R9000 full synthetic oil by Ecstar, which was at the first time use. The gear shifting got a little stiff so I changed. Second time I replaced the oil at 1540 KM just for safety, the gear shifting did not get stiff. Currently, using this oil for third time and I am riding for 1707 KM.
I still have to assess it before I can answer your question. Today I have replaced my bike's oil after 1710 KM. This is the 5th consecutive installment of Ecstar R9000 in my bike. I had to change it because the bike's sound got suddenly louder with hard gear shifts today. I think this oil is not much of a use after 1700 KM. Summary is, in all of those previous 4 installments I could not use Ecstar R9000 more than 1700 KM. Before Ecstar R9000 I used Motul 3100. So I have to check other brands next time. I think I am done with Ecstar R9000.
Yes, you can use Motul 3000 for 1000 KM easily. Just the issue is that the oil is thick and engine brakes hits harder as soon as you ease the throttle.
Yes you are right. But may I don't have that much finger strength to unplug it. But definitely it can be tightened by fingers only from my latest experience.
