Thanks Guys! Basically this is what Iszu said today when I had the vehicle checked out. I guess I was just PO'd when I was only seeing fuel usage comparable to my old Ford 350/v8 van! All my life folks have been telling me that smell was a bad cc. Who knew?Amigo-2k said:The smell is from over spray of under coating. I had the same smell for about the first 7k miles. Also, as your engine breaks in your MPG will go up. At about 15k my MPG leveled off at about 18/22. So no worries. Don't forget to check your oil often on the new engine.
