Yeah it's been a while and for some reason I can't find my manual. Got to do a full oil change on my son's z400 this weekend and I just cannot remember how much oil it takes.. Filter is already handled.

4 gallons.......

OB......

I'm showing 1.8 quarts

I would call the dealer to verify with your year; it may vary by year

Why do they do that why not just make it 2 quarts. TRX is like .75 quart per side Banshee is 1.5 they never make it an even ###

up to the line on the little stick thingie

The HONDA 400 is 1.8 quarts

I have Z400's, last oil change i drained the cases and the tank up front, it took 2 Liters in the tank and it was perfect.

his is an 03, my daughters is an 04. Thank you
and thank you also for the thought of calling the dealers, i'll find the number and see if they can confirm for me

Thank you

you guys are the best... I am and it's just what the dr ordered

1.8 qt

There's a sticker on the oil tank... 2000 ml (2.1 US quarts).

Here's the relevant page from the service manual...

Thank you bunches.. and now that you say it I seem to vaguely recall the info being on the tank... Just been a while since I changed his oil.. (he's done it the last few times but that was last season - time to get it ready for him for this season)

Sounds like your taken care of

Hope so.. this is why I ask questions here, most people are very helpful

Much easier than reading the sticker on the tank, yes

Well since the bike is at home, and I'm at work that's debatable.. And it's easier to get the oil on the way home instead of having to backtrack across town tomorrow.. Plus if I don't know how much to buy and have then I may not even get around to the oil change and be further behind my own schedule

You go girl!!

My girlfriend has a z400. I went by the book when I changed her oil and filter. The book say 2100ml but when I checked the oil level after adding, it didn't register on the dipstick. I had to put in 2500ml in. Just one thing I had to deal with while changing the oil. Thought you might want to know.

I have a question, when adding the oil and using the line on the dip stick for measurement, am I supposed measure it up to the line, and thats it, or am i supposed to start the quad, and then add up to the line?

I have been told to add the appropriate amount of oil, then run the bike for about a 30 seconds, shut the bike off and then check the level....

**edited to add the crutial fact that ehall added thanks

shut the bike off then check the level

Definitely shut the bike off. Otherwise you'll shoot oil all over the front of the quad, the floor, you... don't ask me how I know this

buy 3 quarts. If you run it real good first and get all the sludge out I used to put about 2 1/4 quarts in it.
