2004 Duramax 220000 miles

[Thomas H]

Pulling a travel trailer in Arizona. Found oil on the front of the trailer. Loosing about four quarts every 300 miles. Had the oil warning bell went off as soon as I pulled off the interstate. Anyone know if there is a common problem like this with the Duramax? I have another 3,000 miles to go. Any advice would be helpful. Thank'sl

You'll either have to clean off all the accumulated oil to locate then properly repair the leak or buy 25 gallons of oil and hope nothing let's loose.
