I don't understand why some engines burn oil and others don't. I heard LS1'* burn oil from the get go. My 2000 GTP with 100,000 miles on it didn't burn enough to even notice on the dip stick. My Bonnie doens't burn any either. That'* the way it should be in my opinion.
I usually add 1/2 to 3/4 of a quart between oil change intervals of 4000 to 4500 miles on average. Castrol 10/30- I also drive the car hard with my lead foot. There aint no lettin up when I get the pedal to the medal with this L36, it get'* a beatin.
