I already use bikes from various companies so I can say which engine oil is suitable for my bike. I have been using my Yamaha FZS V2 for about 9 months now and have driven 5000 kms so far. I have been using the Yamalube 10W40 Semi - Synthetic Motor Oil since my purchase, but I will share information about this.
The Yamalube 10W40 Semi Synthetic has been in use since the bike was purchased. There was a good performance from the beginning. The performance is actually based on the mileage. Alhamdulillah, I used the Yamalube 10W40 semi synthetic so I get a pretty good kilometre. I'm over 50 in the city and over 52 on the highway, I'm very pleased.
I didn't feel that the viscosity was low. I changed the engine oil after 1000 kilometres. I don't have much time. I'm a little aware of the engine.
After emptying the engine oil, the bike can drive very smoothly. There is no noise in the engine. I know very much about engine oil so I don't have any issues like other bikes.
Overall, I would like to say that the Yamalube 10W40 offers me half synthetic engine oil. If anyone wants to buy it, I recommend the Yamalube 10W40 semi-Synthetic Engine Oil. I hope my experience with using version 2 will definitely be helpful. Thank you.
