Welcome to the forum 57j2olds1
Most Chinese quads come with a very low quality oil in them. Some refer to it as shipping oil. I would use Valvoline 10w-40 in it. Most hold about 1 qt. Drain bolt is on the bottom of the engine. The filler hole should be on the right side of the engine, towards the back.
