2014 Lexus GS 350 with 2GR-FSE engine (3.5 liter V6). Purchased this car with 13654 miles (CPO). At 20081 miles, changed the oil to Mobil 1 Extended Performance 0w-20. The oil was used approximately 9 months. I used a Toyota/Lexus oil filter. I took this sample at 30058 miles during the latest oil change (also M1 EP 0w-20).
The car is driven approximately 80% hwy, 20% city. Work commute is 19 miles, one way.
Blackstone Comments:
This is a nice first sample from your Lexus, so don't let the highlighted iron scare you. Universal averages show typical wear for this type of Toyota engine after ~6,300 miles of oil use. Iron tracks with oil use, so most of it in your sample is simply from the longer oil run. It should really be closer to 19 ppm, so we left it marked at 25 ppm, but really, we're splitting hairs here. Some extra iron maybe normal for your engine and the use it sees, which is fine. The trace of fuel is harmless and the TBN was good at 2.2. The 4.0 TAN shows mild acidity. Pretty good report!
