1st Oil Analysis- 97 boxster- 26K miles
Just got the results back on my first oil analysis for the Boxster from Lube watch Maintenance Management System (Chevron) - Only concern noted was the lower than normal viscosity. Any expert opinion(s) on the data below? Should I try a different oil? (I know there are some opinions on that!)
M1 0W-40 3000 miles on the oil (Mixed driving, 1000 mile road trip) - 26k on the car, super clean oil filter. Metals (ppm) Iron (Fe) 11 Chromium (Cr) <1 Lead (Pb) <1 Copper (Cu) 1 Tin (Sn) 1 Aluminium (Al) 2 Nickel (Ni) <1 Silver (Ag) <1 Titanium (Ti) <1 Vanadium (V) <1 Contaminants (ppm) Silicon (Si) 4 Sodium (Na) 4 Potassium (K) <5 Water (%) <0.05 Coolant No Additives (ppm) Magnesium (Mg) 239 Calcium (Ca) 2549 Barium (Ba) <1 Phosphorus (P) 892 Zinc (Zn) 966 Molybdenum (Mo) 85 Boron (B) 162 Physical Tests Viscosity (cSt 100C) 11.8 SAE Rating Determination 40 Physical / Chemical Base Number (mgKOH/g) 5.7 DIAGNOSIS All wear levels appear within acceptable limits for first sample. Silicon level (dirt/sealant material) satisfactory. Water content acceptable. Fuel dilution satisfactory. Viscosity slightly lower than typical. Action: Resample at next recommended interval to monitor and establish wear trend. |
