We filled 45ML of GT Oil in one of my friend's 3yr old R15, which had an Engine Oil/Oil filter change at the same time
What I observed was after 200Kms the bike was zooming to rev limiter much faster and totally vibe free and also the engine noise has comedown.
My friend is not sure about the mileage difference, coz he hasn't checked it yet.
One seeing the breath taking performance from a 3yr old R15, We placed an order for a 250ML pack and I have filled my 3yr old R15 with 50ML.and he topped up 30ML to his bike.
We both use Motul 15W50 Full Synthetic oil, the color of the oil is Green. Even while draining the used Motul FS oil the Green shade will be clearly seen.
Now I have 2 questions,
1) My friend has done about 500Kms and the oil has turned Brown and also I find his bike's oil level has come down by 100ML. But the smoothness and rev free nature is still sustained.
2) I have done close to 200Kms, I do not notice any change in performance, engine noise or vibes, its all the same like it was before.
PS: My Motul engine oil at the time of 50ML GTO treatment was just about 500Kms old, the greenish color in the oil was well retained and was almost equivalent to a fresh oil, also Oil filter was replaced while changing the engine oil.
Also I applied the oil in both the bike's exactly the same way as mentioned in the brochure. I.e., applied in cold temperature and then idle the engine for 15mins.
