need to replace them with new ones
You should use Premium. It should say that on the dash by the gas gauge. My 1990 300e does. Hope this helps. I have never had a problem with Regular gas instead of Premium in my 87 300E. As long as you have a good strong spark and clean fuel injectors. I would recommend "Bosch Platinum +2 Spark Plugs" they have twice the spark so you will feel the power increase after you replace your pugs.
