I changed my oil today, four quarts of Mobile 1 (10w30 Full Synthetic) and one quart of Lucus Oil additives. Current mileage at 101K.

Changed oil today, had to use channel locks to pry off the old filter, oil pressure is still high and ticks between 60 and 80, so I guess sending unit might be next. Also noticed sludgy goodness in the coolant reservoir, so I guess a flush is in order....

i like the old screw driver method of getting off old filters.. haha


Take a nice flat head, hammer it right threw the filter and spin her off. works every time, just a little messy

Exactly how I had to do my first change on the Tahoe. Bought the fancy fram filter remover but
The old filter was some skinny POS from jiffy lube or something.

Worst part was, I had the sidesteps squeezing my chest, and my son, trying to be helpful, climbed up to shine a flashlight down through the engine bay, thus further crushing me under the side step. I thought my wife's Honda's filter was in a bad spot, the Yukon is a close second.
