on my 03 ssei, how many miles until you need to change the oil, or do you even need to change it and just watch the level

A lot of people who have their engines modified will change it once a year or so. You probably don't have too many miles on that engine, so it isn't critical to change it.

In most cases, the */C will outlast the engine. For cheap insurance, it wouldn't hurt to change the */C oil once a year.

We have a Techinfo article on it. I agree with SOL. I currently change once a year, but am going to twice a year soon. It'* easy, and I'm spinning my SC at insane speeds. Cheap insurance

yeah my bonnie has only 20k on her, buts its almost 2 years old, is there a drain plug?

On the right side of the snout of the */C, you will see a black plug. Take that off. Use a syringe or something to suck the old oil out, and fill it up with the new stuff. You only need to fill it right up to the threads where the plug goes. You might need a flashlight or something to help you see how much is in there.

Usually it takes 1 and a half bottles of the oil to fill it to the proper level.

Be warned, that stuff smells something fierce.

i just check mine every once in a while... and i added some just after i got the car...

ok thanks for your help
