I have a 2011 Acura MDX with 66,000 miles eating oil like crazy.

about 60% of my oil life got a notice on my dash of low oil had it changed immediately turned out there was about 1 qt left.

After that incident I read up on it and noticed that Acura has extended the warranty and they do oil consumption test to see how much oil it is eating.

They do a 3 visit 1000 mi test, first test after 1000 mi they said it only consumed 0.5 qt oil I know it was not true because before i took it in looked at the dipstick and there was no oil on it.

Before the second 1000 mi test i looked at the dipstick and there was no oil on it again, so i took it to another car shop and had them drain and measure the oil and pour it back without adding any, turned out it was 2.75 qt left, right after went to Acura and they said only 0.75 qt was missing. I told them about the independent shop that they drained it and measured it and gave me a piece of paper saying how much oil was left they kept repeating that only 0.75 Qt needed.

They told me Acura will only pay for the rebuild if it consume more than 1 qt in 1000 miles.

What do you guys think what i should do!?

I been watching this guy on You Tube Scotty Kilmer he is saying that no amount of oil being burned by the engine is acceptable he has 50yrs of experience as a mechanic.

I can't drive my car on 1 oil change because about 50% of oil life i left with not much oil and Acura don't care to fix it.

Honda went to very low tension rings around 2008. There is a problem with oil consumption on some of their V6's of this era. It seems to have something to do with care level. As you are not the original owner it is probable the prior owner used low grade oil and/or extended change intervals. Shmoo on the ring lands can lead to increased oil consumption.

Use a premium synthetic for a year and see if it will clean things up and improve oil consumption. Check your dipstick monthly and add oil. I doubt Honda is gonna rebuild your engine.

These engines are also know to have an issue with a gasket leak on the cvcc hydraulic shuttle valve. Look and see if your consumption is a leak rather than a burn.

Check and replace your plugs as if it is a compression ring leak, the plugs will foul faster than the 100K change interval

Well, we know there is something going on. You need to find out if its a leak or blowby. A leak usually can be fixed and maybe the other might be able to be helped. I believe you can rent a compression tester at Autozone for free if needed. If your car is eating that much oil i would think it would be fairly obvious and smell lovely too.

I am also having issues with bad consumption of oil for my 2011 MDX. I notice the oil consumption right before hitting 100,000 miles. I took it to the Acura dealership and they performed one oil consumption test. They told me it only used .50 quart of oil. After driving 2,000 miles, my low oil light came on. I had to add 3 quarts of oil to get a middle reading on the dip stick. I believe it is a issue with the 2011 MDXs that Acura do not want to resolve due to $$$ they would spend to correct the issue. I am getting my MDX ready for a trade in on a Audi Q7.I am done with buying Acura’s.

I also have a 2011 MDX and it has been a great car. It has been using more oil than normal compared to other cars I own and I have had to add 1 to 2 quarts between oil changes of about 5000 miles. I do all my own oil changes and have really extensive mechanical experience. Recently I did a complete tune-up with new plugs and I ran two cans of seafoam through the intake and I replaced the PCV valve. I have since done two oil changes with no extra oil required in between. I have had to add none whatsoever and the oil level has been stable from start to end. The PCV valve was only $35 and the plugs are denso. Run the seafoam through the brake booster hose running into the intake manifold. Think what is happening is the PCV valve was not closing properly and oil was being consumed and there also sticky piston rings that were loosened and sealed better after seafoam was run through system. I also add 1 oz of seafoam per quart of oil to clean up oil passages inside of the engine to better cool. The car has been running much more responsive and I have noticed more power and better fuel consumption. I think this is a very inexpensive initial try to fix. Between the two cans of seafoam at about $8 a piece, six plugs and the PCV valve I accomplished all of this for less than $100. It is the first time in a while that I feel I don't have to babysit the oil level and I can actually trust the car.
