relationship between oil and cc ???

# Thread: relationship between oil and cc ???

1. ## relationship between oil and cc ???

Was wondering if there is a relationship between the amount of oil an engine takes and the cc of the engine ? and or number of cylinders ?

my 2001 ZX6R is 599 and has a capacity of 4L

how much oil in an SV650 ???

2.

3. Nope. My 9R takes the same amount. My CBX is about 4 as well. My old Seca 650 air cooled took 3.5....... And 2 strokes take an ever decreasing amount..........

4. ummm, interesting I will ask Ron tomorrow....

5. 599cc's here and my bike takes 4L including the oil filter after every change.

It say's 3.7 on the crank case.

6. There is no mathematical relationship between displacement and oil capacity -- it is a function of the shape of the oil pan and crank case. For example, your kwak 6 takes 4 litres, whereas my gixxer 1000 takes 3.3 litres.

7. well I spoke to ron today but forgot to ask him, I am going over tomorrow will ask....

wow, 3.3 for a GSXR1000 I dunno for some reason i expected a correlation between cc and oil liters, thought the bigger the bike the more surface area the oil needs to cover.....

8. No relationship at all. My 9R takes 3.8 from dry, but so did my Valkyrie (1520cc)

9. Well i spoke to Manny today at BK and he told me the only relationship that exist is between the design of the oil sump and the liters it takes he told me a ZX12R only take 2.5 liters I was really scratching my head after that...

6R - 4L
9R - 3.8l
GSXR1000 - 3.3L
12R - 2.5L

seems like the higher you go the less oil.....but anyway I was just wondering.....

10. So Manny told you the same thing as HPman..

My TLR takes 3.8 from dry.

yup....but I still think there is an implict connection as the shape of the oil pan and crank case would be a function of cc or # of cylinders...i think...

Why? All the oil is doing in relation to the cylinders is coating the sleeves, that will take less than a litre to do, even on a 1000cc bike.

Jim.

but wouldn't the oil need to cover a larger surface area given a larger displacement and to a lesser extent depend on how many cylinders ? If displacement is constant i don't think there will be much variation in the surface area the oil needs to cover between a twin and an inline 4.

I just can't understand why the 12R takes 2.5l while my 6R takes 4l, if it's the design of the oil sump then wouldn't the manufacturers ensure that the most efficient displacement design be choosen ? ~ extra oil means extra weight....more or less...

14. The oil will need to cover a larger surface area, however it's not covering that surface area with an inch thick coating of oil.

I don't see any bike using more than 1 litre of oil for the cylinders, therefore, any oil after the 1 litre mark is used to feed the oil system, and replace the oil currently used. Therefore after the 2 litre mark, there is no correlation between the amount of oil and the cc's.

Someone correct me if I'm wrong here?

15. Whay is the sky blue and the ocean green is some spots and yet blue in others???

Oil is a lubricant, it lubs the main and conrod bearings, it lubs the cam bearings, the lifters and pushrods, even small amounts of oil lub the inside of the cylinder walls and etc.

To lubricate all thoes parts oil needs oil passage ways through out the engine, (If you pour oil on the table the thickness of oil on the table is many times the thickness needed to lubricate the engine parts.)

The oil pump moves the oil to theos parts in the engine through the oil passage ways.

Now the oil is pumped throughout the engine oiling all the friction surfaces then drips back into the oil pan, but at higher RPMs the oil pump will pump oil faster throughout the engine than it can drip back into the pan. So, the pan has to be a maximun minimun size or the engine will run out of oil. So if you wanted a 5 gal. oil pan all you'ld do is lose space and add weight to the vehicle. So displacement size of the engine doesn't really matter at all unless the physical size of the engines oil passage ways get larger.

Small block chevys 283 all the way to 454 take 4L + 1 for the filter.

16. ahh....so now there is another factor I didn't consider: the higher the revs. the more oil needed and rev limits to a certain extent is controlled by discplacement, although don't tell that to the MotoGP bikes ....

well I can see my questioning is kinda rubbing the wrong way, so it's cool now, I am satisfied with the answer that I have arrived at, thanks to everyone that participated.
