2014 Yamaha FZ-09, 36K miles. Spirited street riding, no track use.
Out: Valvoline 10W-40 Synthetic Motorcycle oil
In: Valvoline VR1 SAE 40 monograde (dino)
No filter change, Fram FPS6607 is now on its second OCI. I change these every third oil change for a FCI of ~10K-12K miles.
With 600 miles on the VR1 so far, bike is running great. Shifts brilliantly (in fact possibly even better than the oil it replaced), and no clutch issues despite Valvoline's warning about not being recommended for wet clutch applications. Interested in seeing how well the monograde holds up in the long run.
Other oils previously run in this bike: Rotella T 15W-40, T5 15W-40, T6 5W-40, Valvoline 10W-40 dino M/C oil, Redline 10W-40, Motul 7100 10W-40.
