04 silverado clock is at 16,100mi Hi guys, last oil change i put the whole 6 qts in the truck. At time of most recent change (1/26) i pulled about 4.75 quarts out of the fluid. (ran the oil MUCH longer than i should've unfortunately) and put 5.5qts back in 5.5 seemed like enough (i couldnt remember if it was 5.5 or 6) prob gonna put the other .5qt in tomorrow morning. but is 4.75qts out something to be concerned with? the truck went about 10,000mi on the last oil change (is any evap to be expected even when running several thousand past change interval?) ty, drwmbt ETA: Another issue im having and i thought it was from waiting too long of an interval to change the oil, but after turning the truck on (completely warm and temped up) there is a jerk or kick coming from the transmission? possibly when the truck is in parked and being turned back on after a brief stop (such as at an ATM or while getting gas) does anyone know what this might indicate?
