My '97 Mystique 4 cyl calls for 5W-30 oil. Check the owners manual, if you don't have it, Google for it. As for brand, I use Pennzoil, but it's all pretty much the same.

According to the 1998 Mercury Mystique Owner Guide : With engine oil filter change : The 2.5 liter V6 engine takes ( 5.5 liters / 5.8 U.S. quarts of 5W-30 )
engine swapShort answer, no. Based on information from ADP Hollander. Edit:There should be no problem, provided that they were the same type, ie, two V6's or two I4's. I have the engine from a '96 Contour or Mystique in my 2000 Cougar with no problems, you wont even have to deal with the issue of return-vs-returnless fuel systems.
Yes, but if it stays on you should plan to take it in soon to have the engine checked. That is why the light is there.
