Why 5w-20? I would be considering an Xw-40 if I was trying to lessen oil burn.

Right, I went to a 10w30 and it helped reduce oil consumption.

That oil type is incorrect. The engine uses 5W-20. Its even stated on the oil cap.

OP that is a lot of oil. The engine will burn oil.... but not that much. As others have stated replace the PCV valve as your starting point.
Check if you are burning blue smoke from the exhaust. If you are, make note of when and how(i.e Is it at the start? hard acceleration ect)

In the US Honda specified 5w20 for the K24, but 10w30 and 10W40 will work and can help reduce oil consumption.

"Yes, in some countries outside of North America, a 10W-40 oil viscosity is specified for Honda K24 engines, particularly in regions with warmer climates where the thicker oil provides better protection at higher operating temperatures"

having owned a litany of cars - Ford E350s, Honda Civics, Subarus, Ancient and new Toyotas, they never used oil. Ever. If I was 1/4 quart down, I was shocked. All of these cars come from late 70s to late 90s. Hell, I had a 96 4-runner that went 375k miles before my son killed it. Never used oil. Oh, my 2005 CRV sitting on jack stands? Never ate oil.

What I gathered it was just an engine thing with the max. Had a pathfinder with the same engine - it ate a quart as well. With all of the eco crap going on ruining vehicles, I'm just amazed it's tolerated.

Anyway, back to the OP, 4 qts is a lot of oil to go missing as rapidly as it is happening.

Wizard, if you ever find out why, you must let us know.

Astonishing.

Google "how to check for oil leaks using UV dye". That might help locate the leak(s).

You don't state how many miles you drove in 2 weeks, but in any case if you were burning oil at that rate you would see blue clouds of smoke coming out the exhaust. The catalytic converter can burn off some minor oil burning, and the exhaust would still be clear. But assuming you didn't drive too many miles in 2 weeks, 4 qts is a lot of oil to burn. At that rate the cat converter would clog up before long.

My guess is you have a bad leak. And keep an eye on the oil level. If it gets too low it can damage the timing chain, etc.

My 2006 uses a quart every 500 and no leaks at all on the engine, and no smoke at all.

I think it is going past the rings.

I'm running Valvoline Restore and Protect oil which I've read many stories of correcting stuck rings, but I haven't run it long enough to know.

To clarify, should have written that a qt every 500 miles is a bit excessive (1 qt every 1000 miles is acceptable). Typically relatively modern engines use 1 qt every 3-5k miles. I'd keep an eye on it and continue driving, but the cat converter may end up fouled.

If so, it will likely result in an adverse effect on the catalytic converter. A little oil usage is acceptable, but 1 qt/500 miles is excessive.

The original post stated the oil is incorrect and should not be running it. 5w20 is not a incorrect oil.
Changing the oil viscosity is not the issue here.

Correct.
Losing 4 qts of oil in two weeks (unfortunately no info on distance covered was provided) is a massive amount. Serious leak or consumption issue.

If you are in the north atlanta area, I have a legendary shop you can take it too. They are not the cheapest, but they work on daily drivers to support their racing side of the business. They just know old cars and love them.

My maxima (sob, teen driver killed it) would routinely eat a quart of oil between changes. The situation was well documented, Nissan said it was normal (bull$hit), but I loved the car, so I watched the oil.

You on the other hand have a far more serious issue with 4 qts going away. No way it's the valve guides or vale adjustments for that. If it was valve guides you would see the blue smoke. Bad rings - you would still see the blue smoke. Idea: park the CRV on a slope. See if it smokes in the morning. My daughter's 2005 Camry with 250k miles does this, but it goes away quickly. That's the valve guide thing. But she never needs to add oil to the car. Damn thing is legend.

On a whim, check your oil filter. Are you sure you don't have a leak?

"My maxima (sob, teen driver killed it) would routinely eat a quart of oil between changes. The situation was well documented, Nissan said it was normal (bull$hit), but I loved the car, so I watched the oil."

One quart oil use between oil changes is well within normal.

Usually a mechanic familiar with Hondas would adjust the valves when changing the timing chain since the valve cover needs removal anyway....unless records show that the valves were previously adjusted per recommended miles.

Your receipt shows a new timing chain and valve cover gasket.
