Oil Consumption

1 qt per 3k miles?

Give or take, all but my earliest vehicles had that short an interval. To be sure any vehicle I've touched this century, generally they've all been on a minimum 5k interval.

At least in my case according to the manufacturer’s oil measuring device my vehicles worked as designed.

To be clear I'm not arguing whether your vehicles do or do not use oil. I am interested in continuing a technical discussion about what amount, if any, we can measure as being 'used' or 'lost'.

 

As I stated, I measure the oil volume that I have drained from the oil pan and compare that directly to how much I put back in. There is always more going in than what came out. Generally, at a minimum, 1-2 cups, at most 1-1.5 quarts. The smaller discrepancies, were smaller oil capacity engines (5 quart load) and the larger discrepancies were on larger oil capacity engines (9 quarts). 

 

Generally, these never showed any 'measurable' oil loss per the dipstick(s). Oil was always within the marked area. Could it have been higher in the marked area one time vs another, I have to assume so, but the level on the stick never warranted a more significant dipstick reading accuracy check. 

 

I've come to the conclusion that so long as the oil level is within the range on the dipstick the volume is acceptable. Any loss that doesn't exceed the published acceptable use or fall below the dipstick marking is not considered a problem, meaning, the amount that I see being lost are not 'abnormal' or enough to warrant further investigation. 

 

Could it be that your measurement method isn't accurate enough to show an amount of oil loss? (This isn't an insult; I am exploring the measurement limitations of dipstick readings.) 

 

To wit, an oil pan that spreads a large volume over a greater surface area compared to a narrower pan would show variations in their measured volume quite differently on a dipstick.

Don’t get hung up over this. No disrespect intended. People have a different opinion of what constitutes using oil. I stated mine.

Doesnt take an engineer to read a dipstick. Otherwise the manufacturer would require dealership oil level checks. Not brain surgery either.

Ok well I guess Lake disagrees with me on a few points.

• I call oil consumption pretty basic. Rudimentary. He calls it "really complicated."
• I think 1qt consumed in 3k miles is a lot. He says that's normal.

In 22 minutes, he'll use his natural talent to explain oil consumption to anyone watching this video. He covers everything from obvious engine damage to how normally functioning healthy engines consume oil by design.

• Lake explicitly states how you drive will impact oil consumption.

 

Shut up and watch:

I dont care what Lake says. Goodnight.
