Recall for sludge
 At around 113000 miles their is a oil gel/sludge in the engine below the valves. At 131340 miles there was dried oil in the form of coffee grinds in the internal oil screen that filters the oil inside the oil pan cover. WHEN OIL LIGHT comes on at 131340 miles HAVE IT TOWED to your closest dealer or you will be paying for a new engine. Make sure you tell the Service Manager NO ONE IS TO DRIVE IT or let it run at idle.  Or you will have major internal engine damage. I was not notified by the manufacture that there was a recall for sludge ... so if it is smoking that could be the sign that it has an oil gel problem and it is covered by the manufacture. At 131300 miles changed front springs.
