synthetic oil in oil-burner engine

As others have stated, this is a perfect candidate for both Valvoline’s R&P, but more importantly a piston soak at the levels we are seeing, more than anything.

There are several threads on how to successfully perform a piston soak on the boards here; to maximize effectiveness of the soak and also to avoid hydrolocking engine by expelling extra residual solvent from each cylinder, done prior to reinstalling the spark plugs.

That said, the vehicle would need to be able to sit for a few days ideally during this process, and is followed immediately by an oil change after successfully starting the engine post-soak to rid the sump of excessive solvent.
 
The only cure for oil burning in a older Chevy 2.4 Equinox burning oil per GM, is a engine rebuild. Seems the rings weren't the correct size for a few years. But that didn't stop GM from continuing to use them. My '2011, would burn 1 qt every 750 miles. That was with the recommended 5w30 wt oil. The car only has 98k miles on it as of today, so I decided to use whatever helped the situation. What works for me is 10w40 wt oil. It cut the consumption big time. And the engine sounds a world quieter. It may use 1 qt every 1400-1600 miles, depending on how much highway driving I do. I wouldn't worry about using strictly synthetic oil in your car, or if the oil bottle says it dexos or not. It will still disappear fast, so use the cheapest 10w40 you can find. The way I see it, if GM can't build the car right to begin with, why should I take their recommendation for what oil to use?.,,
 
A quart a week!!? How many miles is that?
This cracks me up every time. Shopping for a used car and when asked about gas mileage then getting told tank lasts two weeks...
Back to the subject. My Sportage started burning oil and it got to about losing a quart every 2k miles. After single 3k miles OCI with VRP burning slowed down to under half a quart over 3k miles. I may run another VRP OCI in near future.
 
This is a car that may be on its last legs - what have you done to troubleshoot the consumption? Is it leaking? Is the PCV clear?

New Class Action Claims More Chevy Equinox, GMC Terrain Vehicles Plagued by Oil Consumption Issue

https://www.classaction.org/blog/ne...ain-vehicles-plagued-by-oil-consumption-issue
According to the 43-page complaint filed January 6 in Missouri federal court, the affected vehicles include 2014 to 2017 Chevy Equinox and GMC Terrain vehicles equipped with a 2.4-liter EcoTec engine. The case, which echoes previous litigation against General Motors involving earlier models of its Equinox and Terrain vehicles, says the 2014 to 2017 models have “one or more design defects” that prevent them from properly using engine oil and cause the engine to burn off or consume as much as one quart of oil per 1,000 miles driven.

Oh he is planning on getting a new(er) car next year. Just putting money away to avoid having to finance

Tell your son to keep an eye on the oil and add oil every week, so the level doesn't go below the minimum. Run always full synthetic oil because that is the safest for the car's catalytic converter.
Buy the Super Tech synthetic oil from Walmart because is the cheapest - use 5W30 in the winter and 10W30 or 0W40 (this one is not that safe for the catalytic converter if it says A3/B4 on the back of the bottle) in the summer.
Show the videos and the articles above to your mechanic, if he can do anything about it.

Must be fogging the road burning that much. Catalytic converter not plugged?

I thought my old clapped out SBC was a bad oil burner at ~5-6 quarts every actual oil change (250hrs, roughly 10k miles)
 
i’d invest in a BG 109 EPR bottle from amazon and run it at 2.5k rpm for 30-45 minutes to see if you can get it to stop.
The BG 109 for 10 minutes at 1100. Drain, run 10w30 dino Supertech Synblend (high mileage if they make it) and a bottle of Schaeffer's Moly EP 132, its a pint, you get some additive in it vs lucas. Drive for one week, check it daily cold. If improvements are seen then top off til your jug is empty. Once it starts to play hell again, top off and repeat bg epr 109. Repeat steps. If this works, donate to a beagle rescue if you can. Thanks 👍

have to get your money out of the BG, run it longer lol

What is the solution in the video? I'm curious and didn't want to watch the whole thing.

Is this the same engine in the 2014 Equinox? Family member has one...

The guy did DIY PCV out of the oil cap connected to the brake vacuum line. Also prior to that he run Seafoam through the engine for 100 or 200 miles.
However, those engines have problem with the oil rings as well:
https://www.classaction.org/blog/ne...ain-vehicles-plagued-by-oil-consumption-issue
First of all, the suit says, some of the oil that enters the combustion chamber is burned off, which reduces the overall oil level in the engine and, consequently, increases the risk of engine damage due to improper lubrication.

Second, oil in the combustion chamber that doesn’t burn off may coat the spark plugs’ electrodes and keep them from firing properly or at all, the complaint says.

The unburned oil could also harden and cause carbon buildup, leading to pre-ignition detonation, commonly called “spark knock,” according to the suit. Spark knock, the case says, causes the piston rings to be unseated from their positions and wear out even more quickly and vaporizes the thin film of oil on the cylinder walls, causing it to be vacuumed into the intake manifold.

Further compounding the problem, according to the case, are oil spray jets that “overload[]” the piston rings with excessive spray, and the engine’s positive crankcase ventilation (PVC) system, which apparently vacuums oil from the valve train and ultimately feeds it into the combustion chamber.

We don't know yet. I'm guessing it's the same engine.

Apparently he's still working on the solution.

I tried watching his videos. Couldn't finish. He rambles on and on. I think he's hitting the nose candy a little hard.
 
I don't know why some of the people on here do not actually read the posts. The problem the op is having is widely known. GM has know about their defect for years, and has done everything in their power to do nothing about it. I personally have received a notice from them to bring our car to them for inspection. Their response was, we can fix your car, but you will have to pay for it. The fix is a engine rebuild. We got the car with 35,000 miles on it. My reason for posting this, is to say to all those saying use this "treatment" or "cleaner", "THAT WILL NOT HELP THE PROBLEM". These cars were oil burners from day one. The only thing that will slow down the oil consumption IS, heavier oil or a engine rebuild. The two things that chevy's are known for is, 1. oil consumption, and 2. bad transmissions. If you don't believe that, look on Fb marketplace at how many Equinoxes are for sale, and what's wrong with them. And if the seller says it runs perfect, that means I'm selling it before something else expensive can go wrong with it.,,
 
I'd be more concerned about the catalytic converters at this point. They gotta be close to plugged up with all that oil passing thru them. 20W50 on those engines. Get some Catatclean or Oxicat pronto. Ahhh, don't bother, let her blow up.
