I have been looking for SAE85w/90 but to no avail. Halfords do have gear oil rated at 10w/40 for bikes but do have ones for cars rated @ 75w/90. Not sure which is best to go for - I have a Baotian BT50-QT9.

BTW great site - excellent informative posts.

Two bits of info to add to the above...

1. Buy a 100cc syringe if you can, makes the job a hell of a lot easier. I got one for a couple of pounds off Ebay.

2. Be careful when refitting the drain plug. Because gearbox oil acts to reduce friction between sliding metal parts, it makes it very easy to over tighten the drain plug to the point of stripping the thread in the gearbox casing. It definitely won't go as tight as it was when you undid it, do it up finger tight only then give it half a turn with a spanner, then recheck after a ride to make sure there's no oil seeping out.

Was just wondering if buying better oil will improve the performance of the bike? just picked up Halfords own brand Scooter engine oil and Scooter gear oil both 10w/40 would I be better with the 75/90 car gear oil as mentioned before?

Also wondered how often should be changed? the scooter says every 1500 miles

I used halfords scooter oil and I personal felt the bike ran better than on car oil, It certainly didn't run any worse that the Magnatec stuff I put in before.

My old maunual stated 'change the oil at the first 300 km and 1000km then every 1000km after' and I'm sure thats the standard.

EDIT: I'm sure there will be a few peoply who will disagree with the rating of the gear oil but I think personally 10/40w oil is fine for your scoot as long as it is 'Gear Oil'

I've just done mine today. The guide was right, that stuff stinks !!.

I used Castrol ATF as the replacement and used an oil can with a hose and a pump to top it up.

Only just got the bike, not even done 120kms on it yet but wanted to get some decent stuff in it, as you don't know what they use in China.

Thanks for the guide BTW, really helped out.

Ive had mine for about a week done 60km on private ground, I know where to change engine oil? the dipstick screw one, no idea about transmission e.t.c
Could someone be specific as to what I change my engine / dipstick oil to e.t.c and transmission? I want to get this done as soon as I can. Thanks

Should I change the Castrol ATF I put in my tranny for the other gear oils mentioned here ?.

I just ran a google search for Castrol ATF, and stumbled across a chart somone had produced comparing different gear oils and it said that ATF offers the lowest protection.

I've done 440kms on my scooter, changed oil and tranny fluids at 300kms and it is running fine, cruises easily at 55mph and will go upto 60mph if I really gun the throttle all the way open.

Acceleration is ok initially, then there appears to be a slight dip in the power from about 25-35mph then the power comes back in again.

Just wondered what peoples thoughts were as I don't want to cause any damage to the tranny by using ATF.

Remove the ATF "fluid" now. Read the label and you will see it is a "fluid" not an oil. ATF = Automatic Transmission Fluid
Put in "Gear Oil" 75w90 Synthetic is best.
You have two sets of gears in the trans and they need the properties of "gear oil" not the ATF fluid.
A good synthetic "gear oil" will last 20k miles or even more sometimes, so get some good stuff and you may not need to change it ever.

Cheers Larry.

I'll get right onto it however 'twill have to wait until tomorrow evening. I'll call in and get some from the scooter shop I pass on the way home and do it when I get back. It will have to do me for another day as it is too late now to do anything about it today !!.

Found this in a bike shop near me:

Its a 100ml tube of SAE 90 gear oil, exactly what my manual specifies and it has a handy nozzle on the end for application, no messing around with syringes or turkey baster

I have always used 10W 40 in my transmission gear box, its a lighter oil does the same job and to my way of thinking cuts down friction from a thicker oil. But hey thats only my opinion.

As Larry said ATF is a fluid not really a lubricant so its best to dump that as fast as you can.
