Latest report for our Volvo. Everything trending nicely. I put the same oil back in, so in October when we do the next UOA, there will be less carryover oil of a different kind skewing the results. I expect a higher viscosity and TBN due to 2 consecutive runs of this same oil. Based on TBN and oxidation, this oil could've easily made it to 10k miles, but we probably won't ever push it that far in this car. We're changing it out every 6 months, with typical mileage of 6-8k miles per 6 months.
Air filter has 14k miles on it, and with silicon levels staying low, we're keeping it in for another 6 months.
Total wear metals is 22ppm, for an average of 3.31ppm per 1000 miles. I'm happy with that.
Lastly, fuel dilution keeps trending down ever so slightly.
Gotta say, Oil Analyzers has a fast turnaround! I mailed the sample on Monday, and here it is Thursday evening and I already have results.
