A few months ago I had a 25-row Stillen oil cooler installed.

The guy who did it said it took about 7.5 quarts of ester oil and that sounded about right.

Fast forward to today when I took it in for an oil change. I provided the tech with the 8 quarts of ester oil and told him that's how much it'll need. I picked up my car and went home. Later I opened up my trunk and noticed I still have 3 bottles of ester oil left over. I called the tech and he said it only needed 5 quarts. I checked the dip stick earlier and it looks right.

So I thought about it for a while and I'm reasoning that there's about 2.5 quarts of oil still in the engine, lines, and cooler itself. It's kinda like maple syrup inside a bottle, you can try to pour all of it out but some of it will stick to walls and never come out. Do you suppose this is the case? Or should I be worried that my Z is burning oil?
