How much oil?

I would tend to believe that there is something really wrong with an engine that consumes that much oil, however, BMW has rephrased their oil consumption statement to include the higher output engines as being "normal" when 1 quart is consumed in 750 miles. I find this disturbing on a commuter compression combustion engine car such as yours. I would recommend that you take the car to the point of sale and insist the issue be addressed straightaway, if resistance is met, document your findings and retain legal assistance. The heater issue may somehow be related, be sure to include it in your legal docs. The fact that the engine does not seem to be able to make it to temperature is not normal. Sometimes the dealer just wants to wear folks down and not do anything to fix problems, you need to be unwilling to take "no we can't fix it, it is normal" as a response, hold their feet to the fire, have your wife cry a little, jump up and down, cause a commotion, or you may find the warranty period past and then you could be left holding the bag on this one.

I would only add that while it is technically within limits, I would complain directly to Toyota first. That is to say the corporate office.

That is WAY to much oil in anybodys book.
