I wish to change the transmission oil of my two wheeler. I have drained the existing oil and bought the specified grade of oil from the company authorized service station.The problem is the manufacture's recommend using 120 ml of transmission oil in the sump but the service station guy has asked me to pour 200 ml of oil instead saying that 120 ml of oil is not enough for it and may cause serious engine harm . What should I do?
I found this forum where owners of the Activa (and a couple other models) discuss various stuff. This thread is all about "gear oil changes."
Just at a glance, it looks like the 120mL is the correct answer. I didn't read much more, but there probably a lot more information there too.
I'm not saying that you should take their posts as authority. Honestly, I always say, do whatever the manufacturer says to do. The manufacturer is the authority! Even certified service technicians working at an authorized shop can get things wrong, but the manufacturer will be the most consistently correct (as long as no vehicle modifications have been made).
140 mL is sufficient. Do not exceed.
The only information I could find for a 110cc Activa scooter on Honda's web site was for a Activa 4G.
In the manual it states to use 0.7 liters of oil after just draining it. If the strainer is replaced, use 0.8 liters.
The manual does not say anything about transmission oil.
This information if vastly different than what you have. That means you must be careful. If you overfill the engine oil and run it that way, you could do damage. I suggest starting with the lesser amount then check the levels. Add as needed.
