Just changed the oil in my 2012 RX350. I made a mistake and others my learn from this error. Specs call for 6.5 liters with a filter change. I was in a hurry and put 6.5 liters of oil in the engine before checking the dipstick. The oil was level was well above the full mark on the dipstick. I ended up draining approximately 0.5 liter of oil from the engine in order to get the oil level to the top mark. I assume that when I drained the oil with the car parked on level ground, 0.5 liters of old oil remained in the oil pan. To test this assumption I will raise the front end of the car next time I change the oil. Further, I will run the engine and check the oil level at the 6 liters before adding more oil.
No, oil does not stay in oil pan. If you put in 6.5 L, and had 500ml leftover, it's simply oil not quite filling filter right away. Your capacity is 6.1 L plus 0.4L for filter.
gotta keep on mind that you dont drain all of the oil each time. I add only five qts and 12 oz to hit middle of the dipstick. thats draining the oil for 15 mins

Did you run the engine for few mins. B4 checking? Filter has to soak up some oil needing oil circulation.
This was likely operator (me) error. I will verify on my next oil change. It is interesting to note that there have been several posts by owners with high oil levels after an oil change. I appreciate the feedback and value this forum.
I fill the oil filter with oil prior to installation. That lets the engine oil get up to pressure faster. The paper soaks it up so it may take a couple of pours. Don't fill it so much it spills out during installation.
On any vehicle you generally want to allow enough time (I usually aim for 15 minutes or more) for as much oil to drain as possible and, even so, you may not get anywhere near 100% of the old oil out. As stated above, you also want to underfill, fill the new filter, allow time for the new oil to settle and check the level before topping off.
Hi, needed this forum to help me with my overfill error and trying to decide whether to drain the excess or not as it was not to much, about 5mm passed the max mark.
I took a photo of my dipstick (I guess Australian models have the same dipstick) alongside a ruler and some pages out of the Lexus owners manual to give people some more information that might help them with a similar problem of putting too much oil into the engine.
I worked out that for every 1mm on the dipstick equals very close to 65.28ml so my overfill of about 5mm above the max mark equaled about 326ml or a 1/3 of a litre (assuming that the ratio per mm stays the same above the top mark).
The owners manual says that from the bottom mark to the top mark it will take 1.5Litres to fill. So dividing 1500ml by the 23mm distance you get about 65.28ml per mm on the dipstick.
Hope this gives owners a guide to their particular overfill woes I used the 100 mark so it was visually easier to see that I got it in the middle of the dip stick mark. My manual front cover for reference. Info from manual stating that from the minimum mark to the top mark it will take 1.5Litres to fill.
