Hi,
This is my first UOA on this car.
1997 Honda Accord
2.2L I4
149,900 miles on the car.
7,500 miles on this oil sample.
Half stop and go/half highway.
I ran Mobil Clean 7500 for approx. 7,500 miles with an AdvancedAuto TotalGrip filter. 0.75 quart of makeup oil was added (M1 EP for the makeup oil)
Blackstone's Comments:
Lead was the only element out of line in this sample. It shows excess wear at the bearings and we think it's going to be a limiting factor in how long the oil can be run. This level isn't high enough to think you have any major problems. If you do alot of city driving and/or idling, then the lead may even be normal. 5 ppm is average after 4,900 miles on the oil. The viscosity was normal and no fuel or anti-freeze was present, though the TBN was fairly low at 1.6, so there wasn't much active additive left. Suggest staying with a 7,500 mile oil use for now.
