I am having to change my filter about every 5000 miles . The coolant level seem normal . When I open the Davco's drain valve , only about 4 ounce of discolored liquid drains out. Right after that, it looks like diesel . Could it be the winter blend in this weather ? Truck drives normal .I drain 6 ounce and it rises back up to where it was within a minute of idling . I hope it ain't my cups . Any ideas ?
Detroit 12.7 in 2000 Century . Davco 382 filling up quick
