It does prevent carbon sludge build up.

There's your answer.

I find all this amusing and perplexing. In measuring oil I use the supplied tool. It’s called a dip stick. Using the supplied tool I have been fortunate enough according to this thread not to have oil usage problems in all but two vehicles. They use one qt every 2500 miles. Different manufacturers both said within normal perimeters. I have access to quite a few vehicles. They have countdown meters for oil changes. I figured using that and pulling the oil checking device I could actually show no oil usage problems. I’ll show them I thought. Then I realized I can’t prove I didn’t add oil. So I decided, screw it. I know what I know. If people want to believe that all vehicles use oil. That’s fine with me. I’m not going to get in the weeds. It’s comes down to what your definition of what is, is. Seems I heard the analogy before.

That makes me think of all the years on this farm that I was pouring oil into an old chev 350 pickup engine as long ago it had the fuel pump diaphragm fail and the pumps cast in hole was on the internal side that bolted up to the block to drive off the cam so naturally the crank case was filling with oil and my brother realized this at some point as it was his truck at the time not demoted to farm use but the damage had already been done to the cylinder walls, why the engine didn't blow up with failed bearings all these years later is a mystery. Threw on a new pump back then and kept on using the truck but it burned oil, quite a lot of oil. So many years go by of us using that truck going back and forth to the fields spring and fall and during the fall is when it got used the most. Every few days to maybe a week I would be pouring in another quart or so of oil out of a jug and certainly a lot of the time the oil level would end up a ways above the full mark as more is better than not enough !. Anyway was maybe last year I said something to my brother about the amount of oil that truck uses and was pouring in oil all the time, he had no idea it was consuming that much oil because he never actually checked it himself throughout the year as I did all the maintenance on the pickups in changing oil, doing brakes and so on and he wasn't paying any attention to the pickups oil levels. He still is the owner of that truck, only he didn't realize all this time that it used THAT MUCH oil because someone else was adding the oil.

Stan, is there a chance all those years that you had someone checking and adding a little oil every time you turned your back as they were also checking oil on other pickups and equipment but never mentioned it, they just did it.

@KARNUT not sure why they need to find a way to be right? Dipstick can also describe.....

Early on we all had our own crews and worked different jobs. I was the one who hauled the equipment and campers the most. One brother ran the shop. So each was responsible for our own equipment, maintenance and repairs. Chainsaws, weed eaters etc. We each built, race cars too. I was a bit extreme. I had a lot. I would build, restore get bored sell it get another. To be clear no one touched my stuff but me. Vehicles using oil would go through spark plugs and ruin cats. My one car that did use oil clog the cat. Some people are splitting hairs and it’s rather amusing. I used my equipment hard as well as my vehicles. During my extreme times we used Amsoil maybe that was the difference. We didn’t use measurable oil.

I really didn’t use oil. My vehicles still don’t. They are higher mileage vehicles.

I have 3 vehicles, one of which is a 2016 jeep grand cherokee. My wife and I bought off the show room floor 124,500 miles and doesnt lose a drop. The other is a 2023 toyota 4runner 24k miles same thing no oil loss between oil changes 4k-5k.

Ive owned many cars/trucks since 1981. None used oil except as mentioned before 1968 buick lasbre and my 2024 siverado 6.6.

Dipstick's tend not to lie...

So what does it mean when I say Pepper uses no oil? That for the duration of my chosen OCI there is no perceptible movement in level on the stick.

When I change plugs on the DOD cylinders they have some oil on the threads. Normal. Explained by the above missive. So I know it uses oil. Just isn't a MEASUREABE amount by the METHOD I choose to gauge it by. The dip stick.

Why doesn't it change if it uses oil? Fuel, soot, moisture in a good GDI gas motor can be up to 4% total of the oil volume so in a six quart system at change time could be as much as 7.68 ounces of a six quart system. Call it a cup. Half a pint of lost oil made up by contamination products.

Think it through.

Where does the oil on the spark plug threads come from on the DOD cylinders?

If a motor uses ZERO oil then what lubricates the valve guides and top rings?

Ok, all you hair spitters. All engines use oil because you change it, happy? And according to the manufacturer it’s all normal up to a qt every 2500 miles. Some even more. Probably the question should have been have you lost an engine because of oil usage. So if you don’t add between oil changes you’re using oil efficiency. Just like if you hit the manufacturer gas mileage numbers. At least in my case according to the manufacturer’s oil measuring device my vehicles worked as designed. Gee, I wonder if my tires are using air?

False. That statement is not logical.

"Use" in this discussion refers to consumption via combustion. "Use" in your statement probably means an engine necessitates oil to operate normally.

But no, engines do not either need or consume oil because of the act of the user changing it periodically. Because an engine both consumes the oil that it necessitates it, the user is required to periodically change it to maintain the engine. Not the other way around.

Some of us split hairs for a living.

You are correct on one thing. Tires do lose air over time and that does not mean they are defective or have a leak. And that can greatly affect both efficiency and safety which is why digital TPM became widespread in the last 20 years.

I’m quite bored with this subject. I’ve been mostly amused by the logic presented. I will happily drive along in my non oil using vehicles. That’s my definition and that’s good enough for me.

Hey, who can blame ya? Some people are engineers, and others are end users. Both have to exist.
