2005 Honda Odyssey: excessive oil consumption

Filed Nov 9, 2023 · Engine, Lights · CA

The engine VCM system is burning oil and destroying emissions systems on the vehicle. Catalytic converters are mainly affected as burned oil goes through the exhaust system. The check engine light comes on and the the engine starts to misfire and very abrupt engine vibrations make it into the cabin.

My honda odyssey is burning too much oil than it should. I am needing to add 1 quart every 2 weeks if that as it is already down 1 quart. It is regularly on time going in for oil changes and has been serviced since I've bought it in 2015. It has had many other issues and has been repaired. Now this is seemingly a problem. The oil percentage is not telling me that it is low or none at all. No oil dummy lights have come on when I have not a drop of oil. I have switched and used high mileage oil rather than conventional and go every 3,000 miles & even did a treatment recently. Nothing is doing the job.

Excessive oil consumption with 3.5l vtec engine for which honda was found liable on 2008-2013 odyssey and a slew of other models. My 2005 is doing the same thing yet 2005-2007 cars are not included. Safety wise - when the oil pressure is low enough, the engine will lose nearly all power and cannot safely accelerate (barely maintain speed) yet, the engine oil warning light has never come on in the vehicle...

Summer of 2014 my 2005 honda odyssey was losing power on the road to the point I had to be towed to my mechanic. Turned out I was low on oil with no leaks at all and not due for an oil change. This is very stressful on my engine. My van is only used for local travel, about 20 miles per day and I have been needing to add oil about once per month, still with no leaks. I understand there is a class action suit for honda odysseys 2008-2013 for excessive oil burning, entering the combustion chamber and burning excessive oil at normal operating speeds and conditions. Copied from the internet, http://www.hondaproblems.com/trends/excessive-oil-consumption/ the original lawsuit claims honda hid the problem from consumers. Honda denied the allegation, despite issuing a technical service bulletin (tsb #11-033) in july of 2011 that quietly acknowledged the problem. The tsb states that "the vcm (variable cylinder management) may be repeatedly switching on and off during light throttle operation, at cruising speeds, on flat roads." essentially, the engine is working much harder than it has to in normal driving conditions. In fact, if your commute doesn't consist of climbing through the rockies, you're probably going to see more oil consumption than normal. Just spoke to american honda who advised I need to take my vehicle to honda for an inspection.

We own a 2005 honda odyssey, which was purchased in july of 2005. We started having problems with it in april of 2008. First the catalytic converter went out, then there was an oil consumption problem. We had many oil changes at the dealership and faithfully changed the oil when the computer in the car told us to. But then, it would dump two quarts of oil without any notice. For instance, on may 23rd, 2010, we had a oil change at the honda dealer we had purchased the vehicle from, in anticipation of a 400 mile trip. The car started acting up on our way there and we ended up spending the majority of june 14th sitting in a dealership. We left the dealership and almost made it home before the car started acting up again. We limped into the driveway, but it required towing to the honda dealer in santa cruz, ca for more repairs. They accused us of not maintaining the car because it was two quarts low, yet we checked the oil before it was towed to the dealership and it was full in our driveway. The dealer said it was because we checked the oil while it was off. It wasn't even driven in between until the dealer did diagnostic on it. Then they told us all cars need a value adjustment at 80,000 miles. We have spoken repeatedly with honda of america and honda care and they have repeatedly acted surprised with our problems. They deny that they know or suspect that there is a problem, yet a search on the internet reveals many pages of complaints about several models of honda cars with oil consumption problems.

Excessive oil consumption noticed at 85,000 mile oil change, approx 1/2 quart per 1000 miles dissapearing. No noticable smoke, nothing on driveway. Loss of this much oil between maintenance cycles could cause engine sieze resulting in accident. Service/manufacturer claim this level of consumption is "normal".
