hi all, I hope some of you might have some advise for me. There is an oily reisidue in the spark plugs of my 3003 Hyundai elantra 1.6 petrol car. I have had this car for several years with no problem. however I havent changed the oil for ages, It was almost bone dry when I checked it. right now I have given the car a full service and put in clean oil. However, when i went to change the spark plugs I noticed they were fairly oily. My question is will this have completly wrecked the car or is it rescueable. It has been driving fine remarkably. there was just a funny noirse from the engine that initially caused me to check the oil. Imagine my shock when I saw how empty it was. I have no excuse for doing such a thing, just kept putting it on the long finger. Any advise appreciated,.
