Honda Finally Acknowledges the Problem ... Kind Of

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."

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.

A simple software update should fix the timing issues in the VCM and should be covered under the standard warranty.

Honda's Fallback Plan

If the software update doesn't work, Honda has a fallback plan: to have the mechanic tell you it's your fault:

Talk to the customer about the many factors contributing to oil consumption. This software update should have a positive impact … however, this is just one of many factors contributing to overall oil consumption, including engine braking, frequency of use, trailer towing, etc.

Remind customers that with less frequent service intervals for modern engines, it’s not uncommon for a customer to add oil between services.
