Thanks for the advice J!m!
This winter was the first time that I've noticed this, but this winter was colder than the last 2 I lived here. I haven't changed the oil since I noticed the froth, but it went away after changing my driving habits and letting the engine warm up more.
I have been checking the coolant levels, and they have been looking good. The heat works fine as long as the engine is at full operating temp, which doesn't usually happen during my short drives in the winter. I'm about to flush the coolant too - is there anything I should keep an eye out for when I do that?
As far as oil consumption, over the course of 5000 miles, I go through maybe one quart, if that. I usually add extra oil within 500 miles of the change.
The manual doesn't give an exact engine oil specification. It just has the diagram of the types based on temperature. |
