HONDA CRV 2010 LX Burning Oil

[Andy]

Hi. Eric the Car Guy.
I’m writing this because of worries. I had a 2010 Honda Crv lx which I bought it brand new 7 years ago. I change my oil on time every 2500 to 3000k miles myself. 2 months ago I noticed minimal moisture leak on the valve cover washer seal then I replaced it with a new one also replaced the PCV valve. Then, after observation for a month with new oil, it’s still burning oil every 1000k miles I added 100ml of oil. My car has already 138,000 miles in mileage. I checked my engine weekly with leaks but there is no oil leak. Should I be concerned of replacing valve stem seal or piston ring problem in the future. I don’t wanna shell out thousands of money for this. Next week I will be going to reputable shop to final inspect of leaks. I hope to help me with honest opinion. Thank you and more power to your site.

Honestly, I don’t think the equivalent of about 3 fluid ounces, less than 1/2 a cup, per 1000 miles is anything to worry about.

If you want to get a better picture of the internal condition of your engine, you can do compression and leak down checks.

I’ve measured it about 80ml when I top off additional oil for 1200k miles. Do you think its early for a compression check and leak test?
Thank for thequick reply.

Any “reputable” shop will refuse to take your money for the issue you’re having as that amount of oil consumption is negligible. The truth is, every responsible car owner needs to be checking and maintaining their engine’s oil level regularly. I work at an Acura dealership, and that particular fact really irks my customers when they feel entitled to never open the hood just because they spend 40+ thousand dollars. And when my customers come in telling me it shouldn’t burn any oil at all, that’s simply not true. If no oil at all got past the rings, how would they get lubricated and maintain their seal against the piston wall?

The CRV and the TSX share a similar engine. They do have an issue with the oil control rings sticking in the piston and not preventing excessive amounts of oil from getting into the combustion chamber, but that is pretty rare. I’ve only re-ringed pistons in a TSX a few times in the years that service bulletin came out. Further, the factory tells us to tell our customers that unless the engine is burning 1 quart or more every 1000 miles, there is no problem and any repairs performed will not be covered under the warranty extension. I don’t say this to alarm you, but to tell you that unless you’re consuming 1 quarts per 1000 miles (which is a lot), don’t worry. And your rate of consumption doesn’t even touch that.

All engines burn oil. The amount your engine is burning isn’t even something I think needs addressing. At the rate of consumption you’re describing, it sounds like you likely wouldn’t even be below the lower mark on your dipstick after 3000 miles of not adding any oil. Performing any diagnosis at this point sounds like an exercise in futility. Hope that helps settle your worries.

There’s a warranty extension for those engines consuming excessive oil. Your car is not even beginning to approach the levels of consumption required to qualify under the extension. In fact, your engine isn’t even beginning to approach what Honda considers “normal” consumption levels. Anything under 1L per 1500kms (1 quart per 1000 miles give or take) is completely acceptable, according to Honda.

Check PCV valve.

Thanks for all the replies. I live in Canada Manitoba where extreme cold is high. The reason why my CRV 2010 2.4 is burning a 100ml of oil is
because of the cold weather that shrinks the valve seals or rubber inside the engine, my mechanic says its normal. Now, its spring time I’ve checked my engine oil and stays in high dot level. My mechanics says your engine is still smooth and does not need to adjust valve. My car has 140K and change my
oil every 2500miles regularly with synthetic oil. My car is 7 years old I have change all the fluids by myself, serpentine belt and brake pads. My rotor is still original. Maybe those CRV’s out there that has issues never took care of their regular oil change. Thanks
