Thanks for your reply it goes thru a qrt in a tank of gas depending on how many stops I make just wanted to see if it was common to the engine I've had a few cars that did the same and it never caused them any problems it just got worse as the miles piled on I'm just new to the boxer motor I'm really enjoying the car have u driven yours in the snow I'm concerned about my awd because I can get the front tires to spin I was under the impression that it's supposed to put more power to the rear when that happens or do the back wheels need to slip for this to happen I have so many questions lol I'll try to keep them at a minimum thanks G
