I just sold my crf150f but i still remember how to change the oil, and its pretty easy. What you need is 1 quart of Honda Pro oil (i don't think that synthetic oil is necessary), your owners manual and a wrench (i think that the size is 12 millimeters but i could be wrong). 1st get a good container to put your oil in and unscrew the oil drain bolt on the bottom of the bike and the oil will pour into the container. screw the oil plug back on and then pour the quart of oil into the bike. your owners manual will tell you more.
