You're overthinking this. Remove about a half-pint of oil into a clean container. Check the stick. If you took too much out, pour some back in (aren't you glad you used a clean container?). Repeat until level is 25-75% (edit: or whatever you fell comfortable with) between the dots. Just about every hardware store sells siphon bulb pumps (think squeeze bulb on blood pressure cuffs) for ~$5. You may need to get some smaller outside diameter (OD) tubing to fit down the dip tube.

Well i figured if im half a quart or less ill be able to sleep at night w/o going through the trouble. Thats why i'm wondering about how much over i am.

Let's assume that the distance between the holes is two quarts (64 fl oz). The "H" is a tenth to an eight (10-12.5%) of that distance above the top hole (using my eyeball micrometer). So that would be ~16 fl oz (1/2 quart). I pretty sure it's closer to one quart between the holes.

It's a handy piece of info for the guys at the dealerships that do oil changes, so how much oil between-the-dots represents may be in the Owner's Manual and/or the FSM.

This thread is hilarious.

If that's the case then I'm sure the amount I'm over is not enough to think twice about (even though I already have!). I'm sure the engineers have designed the engine to allow for a small amount of accidental overfill. I mean just think of all the people out there with this car, I'm sure there is plenty who have had the level a tad over without having a negative impact on their engine.

No there isn't any hash mark, just a L, 2 dots, and an H.

Kinda like this: L o----------o H

My level is basically right on the first line of the "H".

oh, thanks for the clarification.... im starting to lose my sight. :ugh:

my G35C's dip stick has hash markings (no dots), so this is why i wondered. :D

To get to the just of this reply; plesae check back to my original post "oil change" back in 7/21/13. From observation and experimentation, i have found that a bad oil stick reading can be in a matter of inches or feet. I use to check my oil hours or days after an oil change. the oil dip stick would read at the H mark. Since nissan was doing the the oil change; i thought this is where the dip stick was suppose to read. I would read the dip stick on level ground in my garage( the car did not roll forward or backwards) So after assuming Nissan's were the bad guys; i took out my level and check my garage floor were the car was placed to check the oil. IT WAS LEVEL. I checked another spot in my driveway. IT WAS LEVEL. But get this; two different dip stick readings. In my garage was high, in the driveway just were it was suppose to be. In conclusion; checking your oil on unfamiliar ground could get you a bad reading of the dip stick. But finding a sweet spot where you can check your oil everytime will give you the best reading.
