I am dynoing my car tonite and am a bit over on my oil change, should i dyno it with the old oil or change it before hand???

Does it really matter??

Doesn't really matter. I mean you should change it when it's due, but if it's ready to be changed or slightly over it won't make a difference. I'd change it, but that's because it needs to be changed, not because you are dynoing it.
