Wow those pics show fancy tubings. My gear oil comes with a little spout so I just open and squeeze. By the way, I ALWAYS use motorcycle gear oils. I use Honda brand for engine AND gear oil. That's cuz my engine is a honda replica, and only the best for my baby. I would not recommend using regular engine oil, or even car engine oil.... I'm sure they make different types of oils for a reason!
Here's a video I made showing me changing engine, then transmission gear oils. http://www.youtube.com/watch?v=q2fSVNYZsSc Hope that helps!

I like my bike as its a cg125 copy so the engine oil also lubricates the gears too!
Thats why I'm prepared to spend £11 a litre for it._________________ Stage6 Speedy:

Here's another example. Go into your bathroom and look at every product. Notice that every single shampoo/conditioner/dandruff product etc etc etc contains Sodium Laureth Sulphate, whatever the brand.
They are all the same._________________

Hello, new to this. My daughter has just started scootering so thought this would be a good place for a look round, learn a bit, etc.
Oil subject interesting. Without getting too anal there can and should be some differences in what appears to be the same oil for a car/bike - mostly due to a collection of additives called friction modifiers, there to work with motorcycle (wet) clutches.
Using ATF in place of gear oil, in this instance of constantly variable transmissions will cause no harm.
Cheers

the CVT on these scooters is a Dry System, no fluid involved. This oil actually should almost be called Differential Oil, or Final Drive Oil, as that is what it is put in, the Final Drive of the drivetrain, not the transmission. Would you put ATF fluid in a differential? I think not.

Just changed mine, at 250 km. The bolts are 10 mm, not 11 and I made a hell of a mess.
First of all they were very tight and I needed a bigger socket handle to undo them. I first removed the fill bolt (I thought they need some air to go in so it could drain better), but because the thing was filled on the side and not upright, some oil came out, like 20 ml.
I then removed the drain bolt, also very tight. Drained it, put the drain back in, tighned it and then the fill bolt.... which for some strange reason does not want to tighten. It's not loose, it has a bit of friction, but it wil just turn around however much I try it. What happened?

| This was my first oil change for the transmission. My daughters bike is a Lifan scooter, and the question is how much oil was needed was given by it being embossed on the casing 0.12 l. I used a 60 ml syringe with the bike on it's main stand with little wastage running from it. What had come out afer a 5 mile run was reminiscent of what our local chippie might discard!

automatic car transmissions have ball bearings, plain baerings, gears, shafts and seals just like these little scooter gearboxes do. automatic trans are actually more complex and intricate since they have valves and pumps to deal with as well as clutch packs. if atf can lubricate a cars transmission with no problems, it can certainly lube these little low power gearboxes with ease.
think about it. an automatic trans has to deal with horsepower ranging from 50-1000 depending on the car. if it can cope with that it then can deal with the sub 10hp motors in these scoots with ease.
also, an automatic trans fluid like dodge atf+4 is a synthetic, costs about $4 a quart. auto trans fluid also has roughly the viscosity of a 5w20 motor oil. so using atf should decrease drag in the gearbox allowing for quicker acceleration and more top speed because of less parasitic drag.
1 quart of the fluid should last for quite a few oil changes in a chinese scoot gearbox.

That's bullshit. ATF should not be use in a scooter transmission, period. Manual transmission oil (hypoid gear oil) is the best thing for the job.
Transmission oil's job is not to lubricate only the bearings (they could have use dsealed bearing for that) but to lubricate the teeth of the cogs. Any mechanichal engineer could tell you that (and this one is doing just that).

This subject of using ATF in the scooter trans has been written up before but bears repeating.
ATF is a hydraulic FLUID - NOT an oil. It has very little lubricating properties and the viscosity is very thin. Just what you need in a complex automotive automatic transmission.
However it is NOT recommended for manual transmissions, differentials, or (scooter) gearboxes (which is what we have in the scooters). These devices are "gearboxes", and as such the gears need the properties of "gear" oil, which are anti-wear additives like phosphorus or the like. Gears also need thicker oil to reduce and distribute the contact pressure between the gear teeth, which is why it is thicker than motor oil or ATF.
The use of ATF in gearboxes WILL shorten the life of any gearbox.
