My Nissan Micra is a 51 usually a good runner however today after work on my way down the main road which is 60 my car would not gain speed. It would only reach 40 at a push. When I’ve arrived to my destination it smelt. I lifted the bonnet and some smoke came out: not a lot, but enough to question. I’ve checked my oil and it was bone empty. I have topped it up and took it for a run and has picked speed up like normal. I only topped the oil up before Christmas. Is this normal or should I be worried?

Obviousy, it is not good if you lost all your oil in a month. However, we need more clarification. 1) What do you mean by 51? 2) 60 and 40 is in km/h? 3) It smelt of burning oil? 4) Was it blue oil smoke or more like a steam? –  theUg Feb 9 '13 at 0:46
I suspect 51 refers to a UK 51-plate, meaning the car was registered in the second half of 2001. This would make the speeds miles per hour. –  Nick C Feb 11 '13 at 13:33
@NickC, is there any link on that topic, so I could educate meself for future reference? –  theUg Feb 12 '13 at 6:33
