Rotella T6 also has more than 1000 ppm of ZDDP which reduces cam wear in flat tappet motors. Yamaha didn’t develop a new engine oil specific to the FJR, likely because any SAE 20W-40 SE or higher grade is sufficient, and Rotella T6 meets API SM grade. Only Yamaha knows why they had to develop the Exclusive gear oil, and they ain’t talking.</p></blockquote><p></p>
