Yes! I had the same issue. I was burning oil deep in the engine and not coming out of the exhaust or dripping. I was burning 1 quart of oil every 1k miles. With the 2010 V6 you need to monitor the oil consumption even though Honda will tell you it's normal to burn the oil. What happens with the ECO is that opening and shutting the valves constantly wears down the seals and causes scoring inside the cylinders. It will also cause vibration being felt when the ECO is on. I had to do oil consumption tests every 1k miles for 5k miles. Luckily I had an awesome Honda tech and Honda paid for the engine to be torn down. I had to replace the block ... Without the extra warrantee it would have been $6800-7000. I would definitely do the oil consumption test. Have them monitor how much oil is being consumed ... Eventually, your engine light will come on if you don't do something about it.... Don't be alarmed if it does. It means that the ECO has shut it self off because it doesn't have the proper amount of oil and you'll be running on a straight V6. I would recommend taking it to Honda but you won't break down .... I drove 150 miles on it. After taking care of that issue I now get 28-30 highway and 25-27 city mpg. Hope this helps .... Check out the Honda forums on ECO problems.Report it
