Owners Manual says oil capacity is 4.5L including filter. However when i drain oil and replace filter and fill 4.5L of fresh oil. I'm almost 1 inch over the full mark

Any suggestions?

Id go with the dipstick and add a little less. Then check it after a few hundred miles.

agreed. and remember that the filter is empty when you first refill the crankcase, and before you start the engine after an oil change.

Also remember that when you drain the oil, you're not getting absolutely all of it out. Fill it to the line on the dipstick, run the engine for a bit, let it sit half an hour and then top it back off again.

Yes i run engine and let it all settle down and it still reads over.

I always need to fill half a litre below the manual spec to not exceed full mark.

I highly doubt it's an design issue or engineers calculations error

Can engine hold half a litre of oil?

Easily, especially if you're referring to half a liter of oil that won't make its way out of the oil drain.

There have been cases where dipsticks have been wrong from the manufacturer.

There have been some cases where the manuals have been printed incorrectly.


Here's an example where the manual was wrong

And cases where the dipstick was wrong

So with that said, need to know what you are driving and dig into that particular model a bit more.

Always trust your dipstick to guide you.

The manual may have published the amount incorrectly or you are referencing a different engine in the manual.
I have been changing oil on my vehicles for over 3 decades and have never had that much variance on the stick vs. the published amount in the manual. I would do some additional research to verify that one.

Lots of engines will still hold oil in nooks and crannies (near the pump, oil cooler, low portion of the oil pan, etc) when you drain by gravity. I do top-side oil extraction on my TDI using a vacuum pump and am able to get an extra 1/8th of a quart that the drain plug does not extract.

I would trust the dipstick.
