I own a Bajaj V15 and was using company recommended engine oil for DTS-i engine. The engine of my bike was producing a hell lot of noise even at speeds as low as 20-30 km/hr. I used to feel like I am driving a truck!! - _- Apart from that I was also facing problems in shifting gears. Today, I got my engine oil delivered by Amazon. Packaging was good and delivery was real quick. As soon as I got my product, I headed to the nearest mechanic available and changed the engine oil. You won't believe it, the harsh engine noise got drastically reduced, riding has now become smooth & effortless and also I got rid of gear shifting problems. To confirm the positive effects, I rode my bike for about 25-30 km continously today and the riding was damn smooth and performance has improved a lot!! Dump that Bajaj recommended engine oil and use Motul!! :) :D Cheers!!
