When i tried this synthetic motor oil for my Kawasaki bike I was amazed by the IMPROVEMENT in the engine`s performance .My bike runs smoother and faster than ever before. The oil reduces friction and wear on critical engine parts, providing better protection against corrosion and heat. Its impressive properties make it ideal for high-performance automotive engines as well. The only downside is that it's pricier than other brands, but it's worth the extra expense for the superior quality it delivers..
