In one of the Diesel Volume books it noted that the 6.2 takes 7 quarts with filter. I put most of a quart in the filter and the rest in the motor. I checked the dipstick and it is reading 1 quart low. I started the motor for the first time, let it run for a few minutes to circulate the oil and fill the oil cooler (useing the Toyota radiator cooler) Added another quart and half to maintain the original level (quart low on the dipstick) Possibly some one changed the dipstick?
