The Wag's oil pressure gauge would read lower than normal and that was the clue. My Bmws have a low oil level warning light.And low coolant too. The current pair sling off a pint pretty fast, then settle down. The Rat doesn't use much oil either.

I did an oil change on a 2011 Forester with the FB engine and 1.5 quarts came out. I think last oil change was 12k miles and 4-5 months ago.

What's a low oil level?

Nothing I have owned or driven regularly has truly been low on oil. Low on oil for my truck is half way down the safe range on the dipstick. At that point it's usually due for an oil change anyway.

The cars I have seen that were more than a quart low on oil ranged from "running fine" to knocking/valve clatter. Sometimes it went away with a change, sometimes not.

This question varies depending on your definition of low and how long it has been there.

"How well does your engine handle low oil levels?"

Don't know, as my oil levels are always 1/16" to 1/8" over the full mark.

Perhaps you can intentionally run a few of your vehicles low on oil and educate us on this conundrum. wink

That is amazing. Because I've ran Saturns with no oil touching the dipstick and you would never know the difference. You must have a very keen sense of hearing.

How much oil is actually in circulation in an engine? Probably less than a quart. I bet every vehicle would run just fine with no damage on a quart of oil. The sump is a resevoir...

Interesting point. With several others raising the same issue, it got me to thinking. Is it likely that when the oil pan is tippy-top full, the windage from the crank makes more of an aerosol of the oil, which is then drawn off through the PCV system?

Or maybe enough oil gets splashed onto the cylinder walls that it overwhelms the rings' ability to wipe it off?

Haven't ever ran one to lower than "add a quart", which is when I add a quart. But the current fleet does not use oil over there 10k OCI so I have had not had this issue for a long time.

On my Saturn I timed it so that it would be needing an oil change when it got a quart low. Ran just fine.

Yea, I pay very close attention.

To be more specific, the engine starts sounding a little "raw".

I check it & sure enough, 1/2 quart low. smile

Saturns of that vintage will take an enormous amount of abuse.
