The specification is ".055 or less", that's from the service manual. Even .070 would not impact the battery much, but point is, the design calls for .055 or less.

I've found our cars to run as low as .010 and usually not run much over .040; if it's over .040, its WAY over, like .360 or .500.
Mine runs very little, .008 or so - but I have no TPMS, Homelink or audio amplifier (it's a base model). I don't think you can get lower than the Base models and I cant remember measuring either of the Limited's that Iv'e owned.
