2018 I had a 2015. 217k hard miles no oil consumption.

Only point I`m making is, this ****** happens.

Oh absolutely, my point is and has been driving style matters not. All brands manufacture faulty engines from time to time.

I joined this website to gain knowledge and entertainment. I like most people lived in a bubble. Like minded people with different talents to build a thriving business. I share knowledge and experience with no agenda. When I retire I did Uber for awhile because I like to drive and you get paid to do it. I wanted to experience different personalities and life experiences. I got an education. The common theme it appears some people don’t want to learn anything. They want parity. Your experience can’t be true. Mine is reality. It’s really simple if you can’t deal don’t read it.

There’s not many people who have had more experience with multiple vehicles than I have.

All combustion engines burn oil, literally, by design. The cylinder walls have to remain lubricated between strokes of the piston which means the rings can't and shouldn't totally wipe the cylinder walls clean when they pass. As such, oil on the cylinder walls is present during the combustion phase and is also susceptible to combustion, i.e. burning. And that's in a perfectly healthy engine with perfectly seated rings with perfect maintenance, whether you use Valvoline or Amsoil or whatever snake oil of your choice.

Anyone with such experience with multiple vehicles should know this; if you are the guy with the most experience and knowledge in this room, we're hosed.

It’s very unfortunate your engines use oil mine don’t. I guess you are one of those who can’t stand that people have different experiences. I’m sure there’s plenty of people even on this website have the same experience. Most engines don’t use oil. Spark plugs would misfire, cats would clog. Vehicles wouldn’t pass smog. You should really quit while you’re behind. You’re looking like a fool.

Yup hes a fool. Engines are not Supposed to burn oil, oh ask NASCAR and Indy noone adds oil at the pit stop...

What I find far more disturbing is when I see an engines oil level slowly rise because that is NOT a natural occurrence of a mechanically sound engine and fuel system, or engine design to begin with. In one instance I sent in an oil sample to the Cat lab because its here in Alberta from a diesel tractor and sure enough it came back that it had a certain percentage of fuel dilution and I called the lab and talked about the results and he said with this particular engine it is a known common issue and that the engine does NOT like idle time even if fully warmed up as it make it worse yet for fuel dilution issues. The answer basically was to monitor it as per the level, try not to let it idle any more than I have to and ultimately change the oil more often before the diesel dilution gets to a critical point. Of course this engine in question has the idiotic EGR that makes the oil black as tar after running it for one day, thankfully it was before the dpf and def was forced onto farm equipment. I'd much rather have an engine that uses a bit of oil because its typically natural for engines to use some oil over time and that the oil does not get black instantly vs an engine that is forced to swallow soot down its throat and due to weird fuel timing for emissions purposes end up with fuel dilution in the crank case.

My engines use oil, yes. As do yours.

However, you lack the ability to perform higher resolution analysis of data points in relation to your own experience. It's OK to acknowledge your blind spots or where you need to incorporate information to change your incorrect views.

I've got 7 vehicles in the fleet right now, two are diesel. Four of the gas engines use virtually nothing; we'll call it "nothing" but oil usage is actually non-zero, it has to be. They burn completely healthy amounts of oil for their use and design which really isn't noticeable during a typically oil change interval. That doesn't mean they don't use oil. You? You'd say they use "no oil" and it's not possible that they burn any oil. And that's simply untrue. The only vehicle that doesn't burn oil is our EV.

The diesels I described above. The small diesel is too new but is explained to burn oil during early mileage by the manufacturer and that matches my experience with other new diesel engines. The medium diesel burned when new and now burns acceptably normal which is almost nothing--but it's never zero.

That's just a dumb question. Because the engines have big enough sumps to keep the engine lubricated during the race, usually 12-14 quarts. Adding oil could cost precious time, or the entire race ($ millions and millions in sponsorships) and the potential of spilled fluids leading to disqualification.

But that doesn't mean they don't burn oil. Burning 2 quarts isn't unusual for a 500 mile Nascar race.

If you want to be technical. They use all fluids because you change them. But that isn’t what the thread was about. I’m not going to list all the vehicles I own or have a percentage of ownership in the family business. It’s enough.

Yep. Idle time can wash the cylinder walls and dilute the oil and add volume to it over time. On a smaller scale, the owners manuals for small diesels and gasoline direct inject engines for cars tell owners to limit idle time.

EGR is a different subject but I agree. 8 quarts of fresh translucent oil in a modern diesel with emissions and it turns instantly black.

When DI systems malfunction they can leak fuel into the oil system...not uncommon for people to see another half to full quart over full on the dipstick before they realize there's a problem. EEK

What? That makes no sense and nobody cares about your family business ownership stake here.

And yeah, I am technical. We're talking about engines on an enthusiast forum.
