Previous oil was GC; replaced with RLI 0W30 on January 7; sampled i.e. NOT drained on August 7th.
I know it is easy to say a passenger car experiences severe service but I think this one does qualify.
For most of the year (including an Ontario winter) it is short tripped M to F i.e. 1.5 miles to a train station parking lot, sits all day then returned home in the evening. So coolant let alone oil rarely gets up to operating temp. I know HWY miles would help on the weekend but this is not likely to happen.
This sample was drawn using a hand pump. I wasn't going to drain and fill until I got back the analysis (Dyson).
[Probably a 10 to 15 minute HWY run was done prior to sampling so likely the fuel dilution # shown here is (very?) understated given the driving routine experienced by this car.]
Will do a full drain today or tomorrow with Toyota 0W20.
