From a 2008 Saturn Aura with a 3.5L V6, 26860 miles on the car and 7775 miles on the oil, I used the GM oil life monitor down to 0% left. Using Castrol synthetic Blend 5W-30 oil and an AC Delco PF-61 filter. The engine holds 4 quarts, the oil lasted a little more than 4 months. Iron 24 Molybdenium 7 Copper 87 Silicon 9 Sodium 174 Boron 6 Calcium 2304 Phosphorous 485 Zinc 598 Solids .1 Glycol NEG Water <.5 Viscosity [email protected] 57 PH 5.2 TBN 2.18 Fuel dilution 1.1% All other reported values was Zero. Are the metal values too high? The fuel may be because the car was only driven 3 miles before the oil change.
