molson had said to add a quart of mystery oil 500 to1000 miles before doing an oil change, i did this with no problems. My question is on the bottle it said to add 20% in with the oil at oil change. Wondering if this is about the same thing or if there are any advantages to doing it right before oil change?

20% is about 1 liter for 5 liter of oil, putting the Marvel Mystery oil before the oil change will clean out all the carbon build up in the engine and free up your oil journals and passageways. Good indication it's working is to inspect your PVC valve, you should see the part that is in the engine cleaner then the last oil change and you'll notice the amount of carbon collected with the old oil compared to the past oil changes. Keep up the great work Kyle
