Like a lot of us, I tend to get the "Evil Eye" from my wife when I start any new project on this car. On top of that I have learned that it can be a bit pricy (hard to hide from said wife). In most cases dealing with this car I like to do things the right way and try not to cut any corners. That's one of the things that make me proud to drive this car. But with that said, I'm leaning towards just running the car a half quart low and not worrying about it. As said before in this post, I don't think that much is going to matter on the low side and only allow the smoking/potential plug fouling on the high side.
