2013 Accord V6, Honda oem 0w20, 5K on oil, OLM 40%, 75k miles on car. First uoa on this car.
Car makes a couple of cold short trips (1-2 miles) 3-4 mornings per week and rest of it is a mix of city and highway driving. Doesn't burn a drop of oil.
There is a bit of a story behind this uoa and I was surprised this report came out a lot better than I had expected. Here goes -
Every time the OLM dropped below 50%, there would a noticeable increase in engine noise, a noticeable drop in performance and there would be a fairly strong (at least to me) smell of fuel in the oil. At that point I'd scratch my head - should I dump the oil or trust the olm ? And eventually I'd take an intermediate approach of replacing the oil filter and then topping off with fresh oil - about a quart or a bit less. Total capacity is 5qt. The noise goes away, car runs smooth and performance is restored. I thought this means the oil has deteriorated significantly and I should expect a crappy uoa but apparently not so from this report. The only thing I can see is that the viscosity is at the lower end. I did not do a TBN thinking maybe from other other mineral, wear and viscosity numbers we could make a good guess. I was surprised to find high flashpoint and low fuel dilution.
So what do you guys make of this ? Curious to know what your thoughts are on this.
