2000 Honda CR-V, B20Z2 engine with 215,000 miles.
The car is burning about a quart a month, and I’m still using the manufacturer’s recommended 5W-30, always synthetic.
I live in South Carolina, so we don’t have to worry about sub 0 temps, and honestly, we only get below freezing about 2 weeks out of the year max.
Can I start running 10W-40 in it? Will that help with the oil consumption? Without an engine teardown, what else can I try?
Thanks

I will always advise to not change the oil viscosity from the manufacturer’s recommendations. Going to a heavier oil is not going to do anything positive for you.
You could try switching to mineral oil of the correct viscosity. At least you won’t be spending as much to keep oil in your high mileage engine.
If you plan on keeping this vehicle, you have to accept that it’s at the point where it needs repairs. A compression test and leak down test will give you some info on the mechanical health of your engine.

+1 on the compression and leak down test
Start by checking for oil leaks–valve cover gasket, oil pan gasket, oil drain plug, etc.
Make sure the hoses for the PCV are in good condition and the PCV valve is working.
They eventually gum up and stick.
If the PCV goes bad, it can cause oil use.

After 17 years of heating and cooling, it is probably necessary.
