Reviews of YACCO engine oil

I opted for 10W-40 full synthetic oil (Yacco 1000 MVX 4T). Post-change, I've encountered a couple of issues: Reduced Power: There is a noticeable loss of torque. White Smoke: White smoke is appearing from the motorcycle, but it's not emanating from the exhaust.

I opted for 10W-40 full synthetic oil (Yacco 1000 MVX 4T) and a slightly taller but compatible oil filter (HF204).

Post-change, I've encountered a couple of issues:

* **Reduced Power:** There is a noticeable loss of torque, particularly, the sixth gear feels slower than the fifth.

* **White Smoke:** White smoke is appearing from the motorcycle, but it's not emanating from the exhaust.
