REVIEW BY READER: ZDEN
BIKE 2013 KAWASAKI NINJA Z250 2 CYLINDER
MILEAGE ON THE Z250 BEFORE LUBRICANT REVIEW: 18900km
NASA GD7 Fully Synthetic Motor Oil 5w/40 API SM/CF Review
0-500km
i-Moto has sponsored me 3 bottles of Nasa GD7 Fully Synthetic Motor Oil 5w/40 for me to review. I am using Kawasaki Z250 and the bike uses up to 2.5L of the engine oil.
I can feel the power has restore right after the engine oil is replaced.
The bike feels so much lighter and more torque compare to the previous engine oil.
The FC has improved a little since oil changed.
The engine oil still looks clear after runs about 300km.
After the engine oil heats up, which i full-throttle for around 15 minutes,
i encountered ‘miss-gear’ when stop-and-go at the traffic light.
It happens only twice during the 500km runs.
Overall, the engine oil still satisfied me.
500-1000km
The engine oil run continues till 999.4km in 5 days time.
During this period, the engine was smooth and i only encountered ‘miss-gear’
twice.
The color of the engine oil turns dark brown but the performance still remain.
At 640km, i added 1 bottle of NASA Oil Treament to improve the engine performance.
Probably because of 1 bottle, i could not feel any difference since the
addition of the oil treatment (the bottle states that add each bottle to
treat every litter of Engine Oil).
I brought the bike to K. Klawang in the afternoon (12pm – 2pm), the engine
roars like a champ and feel light. But i still encountered ‘miss-gear’ once at town area after the touge.
Overall, the engine oil still good at the moment.
1000-2000km
During this period, the engine oil still working like a champ. The color turns dark brown at this stage.
As daily bike, during the run, the engine still running, feels smooth.
I also ride to K. Klawang during this period and the engine is still powerful.
As for miss-gear, the number has reduced.
