Hello all, I recently purchased a 2008 yzf 450 and just wanted to make sure I am adding the correct amount of oil into my bike. With an oil filter change it is 1200cc correct? How much oil should I use if I change the oil without doing a filter replacement? I printed out some directions online but just wanted to be sure. Any tips or suggestions would be appreciated! Thank you

I believe you put in a little too much.


If you change the filter - 1 liter

If you DONT change the filter - 1 quart

Oil change procedure from the sticky's:

1.2L is the total amount required if you are filling the engine after a complete rebuild. During maintenance oil changes, there is roughly 200cc of oil that will never drain, which explains the difference. Read the procedure linked above, and grab a manual online. :thumbsup:

Yea I think I did put too much in but when I drained it after the first oil change there was approx 1200cc/ 1.2L. I orginally put in 1L but after seeing the 1.2L from the previous owner I added the extra 200cc. The instructions say 1L with oil filter and .95L without. I'm sure it won't hurt the engine to add 1L of oil with every change? It will be much easier for me to just add 1L with every oil change...

If you drain the oil properly from both points and change the filter, it takes 1L. If you leave the filter in, it takes a quart, so you either dump the quart in it and forget it, or fill your quart oil bottle to the 1 liter mark from another quart and dump that in. It can't get any simpler.

* If the oil brand you use doesn't come in bottles with a level indicator on the side, and/or doesn't have a 1 liter mark, add 54cc or 1.8 ounces (50cc and 2 ounces is close enough) and pour that in.

Overfilling the engine by 200cc can actually cause problems, so don't do it. The excess oil ends up staying in the sump where it coils around the crank and over oils the cylinder walls, causing power loss and oil combustion in the top end, which leads to carbon build ups on the piston and valves.

There are 946cc in a quart, so the difference is 54cc the way I work it.

I have the same bike. After I let it warm, I drain the oil from both drain plugs and clean my Scott's stainless filter. I add 1-quart and using a ratio rite, another 9 oz. of oil. Bike always measures perfect on the dip stick. I use Amsoil 10w-40 and love it!

Too much oil. 41 ounces is 1.2 Liters, and that's a 200cc overfill. The bike will read perfect on the dipstick with 1 liter, 1.2 liters, or 2 liters, because there is no room in the oil tank for anything more than gets pumped back after a 1 liter fill. The excess is forced out of the tank through the external line that connects to the right side crankcase cover, and the sump level is kept above normal, as I posted above.

Looks like I'm pulling my bike out and draining about 7oz a.s.a.p! Hopefully I haven't done any damage putting 1.2L each time I've changed the oil. Thanks for the info.
