Honda Piliots with VCM oil consumption thread (All Honda Pilots 2009+) . [UPDATE 2/NEW CLASS ACTION SUIT 11/6/13.. 8 year warranty or paid repairs! (see post #26)]
Seems I'm the latest to get bit by the VCM bug (oil eating/plug fouling) in Honda engines. Seems Honda knows about problems with the V6- VCM system and are remaining tight lipped at the moment. The more complaints the better. In my case I have the dreaded P0303 code...misfire on cylinder 3 at 55K miles. Lots of oil used.
Here is Honda's official statement....
The Regional Case Manager at American Honda today. He again confirmed the Honda position that "... it's normal to use up to one quart of oil every 1000 miles", and stated that Honda does not intend to change this stance unless there are more complaints. So please, if you are experiencing this problem with your Pilot (or other Honda V6-VCM engine vehicle) using up oil let them know by calling, sending a fax or a letter. I received a quick, personal response but nothing will be done unless we flood them with complaints. Thanks.

"We do not *think* it has anything to do with the VCM, but Honda is tight-lipped right now. As was stated, VCM has been around since the 2005 Accord Hybrid and Touring Odyssey. The newer model Accords ('08-up) suck a little bit of oil during VCM mode, but all this has been causing is fouled plugs (usually #2 or #3), and probable misfires. The oil that is sucked through the valve stem seals is enough to foul the plugs, but is not noticeable on the dipstick.
So far, Honda themselves have kept their mouths shut about this issue, but we have seen (and confirmed by an American Honda employee I choose to leave un-named for his sake) that the new Pilots may burn as much as a quart every 800 miles!!! Check your oil!"
MY own vehicle was down over 2 quarts after just changing the oil 3 months ago.
Important: If you own a Pilot 2009+ CHECK YOUR OIL EVERY MONTH! USE 5w-20 only!
There is a TSB out also TSB 10-063 applies to all 2009/2010 Pilots and many 2011
And another TSB....
in July of 2011 Honda quietly acknowledged the problem in the form of a Technical Service Bulletin (TSB #11-033). The TSB says the probable cause of the problem is "the VCM (variable cylinder management) may be repeatedly switching on and off during light throttle operation, at cruising speeds, on flat roads."
PDFs of TSBs
Some dealers are doing goodwill "fixes" up to 75K miles and replacing engines for $500 in some extreme cases.
BEWARE VCM Honda's...the technology stinks and uses up oil. BE AWARE.
