Maybe Brad Penn is only giving you 7/8th of a quart per quart of oil.
Kinda like Subway, home of the 11" foot long.

I don't think I like the idea of running a engine with no oil as sometimes a worn oil pump that's empty might not pick up the new oil. One interesting fact is, if you drain a Nissan Nevara and go to lunch, If you come back from lunch and top it up. It will not pick up the oil. Modern stuff is wonderful.
For a good flush, we used to drain the oil, then half fill with oil and kerosene. Idle the engine for 15 minutes. Then drain. It would really clean out the insides. Then when you refill it, the oil would look clean after a week. It doesn't mix with dirty oil that was left in the engine.

750HP was just having a bit of fun. Nobody with half a brain would ever run their engine without oil unless they were just doing an experiment to see how long it would run before seizing.

Now, I also put air in my tires and I noticed there was some missing air from there as well....

I am thinking that your tires are not the only place that there is some excess air leaking.........

Ya got that right. I remember going to something, somewhere, where the exciting attraction was an almost junk car would be run without any fluids and whoever guessed how long it ran until it seized up won a prize. It actually ran much longer than you might have thought, like five to seven minutes, as I recall. Maybe they had extra air in the tires.

What do the elevated levels of sodium, calcium, and magnesium mean? And, is this conventional or synthetic oil. Thanks for posting this.

Sodium, magnesium and calcium come from the additive package and detergent qualities of the oil.

Thanks. Good data.

Of course not. I'm simply providing a benevolent service to others, out of the goodness of my heart.

Speaking of tests, I had my "Body Composition Test" yesterday. I'd say it's a bit more important than testing your engine oil.

Yep, most of the guys around here will be long dead before there's any appreciable wear on their Cobra engines anyway -- regardless of the oil they use or the interval in which they change it

That said, a UOA is pretty handy to red flag obvious problems that will eventually lead to a very bad day. They have little vacuum pumps and surgical tubes, that you fit down your dipstick hole, to make it extra easy to get a sample, for those that are interested.

Are we still talking engine maintenance or now off to body health testing? Sounds a little too much like my digestive health doctor's lingo.

I tried to read through this thread but couldn't do it. So if this has already been said then excuse the repeat. The ONLY explanation for getting 1/2 qt more oil on an engine drain when cold vs. hot is that "extra" 1/2 qt is what would normally be held in the engine from circulation and wetting all oil quenched surfaces. Let it sit and cool down, then that oil drains back to the oil pan.
