Mazda is working on the excess oil consumption issue according to the factory. ...
The TSB from last year already mentioned a probable connection to valve stem seals, so I wonder what they're still 'working on'.
.... I found the consumption test and if your vehicle doesn't exceed 1,200 miles per quart, you don't have a problem=BS in my opinion. Ed
Based on the length of time that's elapsed since of the release of the TSB last year, I've been suspecting for some time that Mazda might just bail out by taking no action at all on this issue. And they seem to be confirming that by suggesting that anything even remotely close to a usage of 1.2 quarts per 1K miles is ok for a nearly new vehicle.
Yes, it's total BS, however Mazda is holding most of the high cards in this game. They can choose to call this level of oil usage normal and not make any repair, and there's no way to force them to do anything. About the only weapon an owner has is taking them to court, which is typically going to be a RPITA, with a crapshoot result. And given that this is not a safety issue, complaints to the NHTSA probably won't get much traction either. Perhaps something emissions-related, but that's probably a stretch as well.
Not a happy prospect at all on this, but I hope I'm wrong and Mazda eventually comes through for the owners.
