Oil Capacity between the dots on the dip stick

nis350

I was wondering if anyone knows the accurate capacity between the upper and lower dots on the oil dip stick.

During my recent oil change, I poured in about .75 quart of oil and that moved the mark from about half way to about 80% near the upper dot (I waited a couple of hours before checking). Based on that measurement, it appears that it is about 2 q. between the dots which I think it quite high?

Another question is where do most of you fill the oil up to relative to the dots? I left mine at about 80% full.

Thanks...

Top dot... if we're gonna be specific about it.

but MORE is not ALWAYS better. Oil fill is an example of that.

EDIT: should be about 1QT from bottom to top of dipstick.

i like to fill to 0.027mm from the top dot

Most dipsticks are "calibrated" so that there is about 1 quart/liter between the H and L marks.

I aim for about 75% "full" but some engines seem to like a little more or a little less.

To sum it up: no hard and fast rules.

Owner's Manuals sometimes have that info. Or, in this case, maybe the FSM.

That's way too low,be careful,your engine might seize!
I've always been told it's a quart in between the lines. And I don't recommend over filling it.

It made sense to be about 1 quart between the dots, but I think it is more than that based on my measurement.

I filled it around 80% full which is on the upper range of the dots. I don't want to over-fill it.

i buy the 5 qt bulk and after pouring the entire jug into my vehicle, i drive around and wait until morning to check. its always at the 75% mark between the two dots

I keep mine topped off at the top dot all the time. Since I switched from Redline to Pennzoil Ultra the consumption dropped from 1.25 quarts/5K miles to about a half quart/5K miles so it's much easier to monitor. I don't know if the drop in oil consumption was coincidental with the change in brands, maybe it was because the engine had about 35K miles on it when I switched and was finally settling down but at least now I don't worry about the oil level dropping more than a few mm below the top dot before I see it and add a few ounces of oil.

1.25q/5k miles seems a bit excessive and was a good idea to keep the level at the upper dot just in case. .5q/5k miles is probably normal for our motors.

Just putting in 5q is probably not a bad idea as other poster suggested.
