Change The Oil Or Wait A few Hundred Miles?

I would go ahead with the oil change unless you know a PDI was done one it.

You have the transmission oil right. 80/90 is correct. You should use 10W-40 oil though. Air cooled engines run hot and the extra viscosity will help.

I was always told that the manufacturer uses a "break-in" oil in both the motor and reduction/gear box and to change them at 600 miles. Not sure how true that statement is but I've always stuck by it. Also noticed every new scooter I've ever owned the factory "break-in" oil had a strange color tint to it. This was in new Genuine (Buddy 125), Yamaha (Zuma 125), Suzuki (Burgman 200) and my Piaggio (Liberty 150). Also my friends Lance (Cabo 200i).

Today I decided to change my motor oil & gear oil even though I only have 10 miles on my BD50QT-2A 49CC - scooter made by Jiangsu Baodiao.

I don't trust the oil/ gear oil that comes from the factory, so I changed it today, then rode over 20 miles with no issues.

When should I change the oil/ gear oil again? I was thinking of 500 miles? Just curious what your thoughts are?

I used Castrol 10w40 oil for the motor and Castrol 80/90 gear oil.

Also, down the road, what are your thoughts on synthetic oil?

at what mileage I should consider full synthetic?

I was going to change to Castrol POWER1® 4T Motorcycle Oil.

I was told this is a great oil to use when I change over to full synthetic?

At what mileage is it "safe" to change from conventional oil to full synthetic?

Also, which oil do you like best??


It has great reviews and is formulated for 4 stroke 49 cc engines.

your thoughts??

You don't have to run motorcycle specific oil, because your engine does not share a clutch assembly with the engine oil. Motorcycle oil uses different additives to prevent clutch slippage. Won't hurt anything if you do, but regular automotive oil is fine. Switch to synthetic around 1000 miles. Give the motor a good break-in with conventional oil first. Oil brands are very subjective. I use whatever Piaggio recommends for my Liberty. The change intervals are 3000 miles. On most China scooters people seem to change the oil earlier, 1000 to 1500 miles. Curious to what others suggest. I always forget about the reduction box oil, so it usually gets change whenever I remember, around 5000 to 10,000 miles. Another important thing is check the valves. Mine is every 6000 miles now. First check was at 600 because it was new. Some people do their valve checks more often. Not hard at all with You Tube videos. Also check the tire pressure weekly. Finally, enjoy your new bike!
