Brand: Q8 Excel
Oil Type : 5-40 fully Synthetic
Price : RM165
My Thoughts : Excellent durability and revving all through its lifespan. I change my engine oil at 5000 KM. Good cleansing properties and reduce tappet sound (If tappet sound too loud need to go and adjust)

Brand: Sumo Racing R1
Oil Type : 5-40 Fully Synthetic
Price : RM180
My Thoughts : Was curious of this brand. Engine felt a bit coarser and tappet sounds a bit louder even after adjustment. Smoothness deteriorates at 5000KM mark. Not recommended.

Brand: Mobil 1
Oil Type : 5-50 Fully Synthetic
Price : RM149 (Carrefour) | rm189(bulk buy)
My Thoughts : One of the best oils I have tried. Excellent lubricity and oil break down is very minimal at the 5000km mark as shown by the way it flows when draining the oil. Expensive though. I guess AMG, Porsche and Nissan (GTR) chose this oil as their standard recommended lube based on its excellent performance that I can vouch for.
