I cant seem to get a clear answer on which motor oil is the best for the 150f. Also where does the oil drain out of and where is it?

Thanks in advance

And to add another question, what is the oil capacity for the 150F? I got a used one with no manual and I'm used to there being a clear marking next to the filler hole telling the amt to put in, but I find nothing on this bike.

You will never get a clear answer on what one is best. Just use a good quality non-energy conserving 10W-40 and change it often. I like synthetics but there is nothing wrong with conventional or blended synthetic oils.

There is an advantage to synthetic blends as if you find yourself down some oil and don’t have synthetic around you can top it up with conventional oil.

However there is no doubt that synthetic is best for your motor.

No idea on the capacity of the 150 but you should have a dipstick on it.

I have an '05 crf150.

The owners manual for my bike says the bike will take 1.1 quarts after an oil change. I have been using 1 quart of oil.....
The oil plug takes a 24mm socket. The oil plug is located behind the shift lever on the left side of the bike. You should start the bike and let it run for a couple of minutes, then shut it off and let it sit for a couple of minutes before you drain it. Be careful when you remove the oil drain plug, because there are several parts to it (plug, spring, screen, etc).

I too would recommend using synthetic oil. My opinion is that a person should use conventional oil for the first couple of oil changes so that the engine "breaks in" properly and then switch to synthetic. Maybe I am being too cautious, but I change the oil every other ride.

Thanks fpr the replies, but what is "Be careful when you remove the oil drain plug, because there are several parts to it (plug, spring, screen, etc)." - This is something I should look out for when I remove the drain plug?

Thanks

It will become obvious after you thread out the bolt. Behind the bolt there is a spring that will come out as well. This spring holds a little metal screen filter that will come out also. If your careless when you do this you could be looking in the laneway/garage for these parts they could fly off or be fishing them out of your oil container.

It’s just a heads up on what to expect.

Thanks guys. Changed it last night. Old oil was nasty, but it's all good now.
