Virgin cST@ 100 degrees C0.5 ppm Fe/1000 miles and a TBN of 8.5 after 20,000 miles?! That is out of category outstanding!
How much was the viscosity rise in 20,000 miles?
Keep in mind the TBN method they used is D2896, which is supposedly more suitable for virgin samples than used samples. It reads anywhere from 1-3 points higher than D4739. Still, even if you subtract a couple of points the TBN is really impressive.0.5 ppm Fe/1000 miles and a TBN of 8.5 after 20,000 miles?! That is out of category outstanding!

The same oil filter was used. Mobil 1 Extended Performancd M-103A. Factory air filter is still in place.The Fe wear rate is incredibly low. The other metals are just noise.
There's no contamination to be concerned with.
The base is still very strong.
This is still very serviceable fluid.
What was the filtration used for this sample?
True. Climate. All my conditions have proven to have been easy on oil.Very impressive results. Not to take anything away from the oil but it probably doesn't hurt you're in such a mild climate.
I'm a big fan of this 2.0 engine. I was happy to see it become standard on the corolla for 2023. Makes the LE a really strong value proposition.True. Climate. All my conditions have proven to have been easy on oil.
I actually had previous 180k miles of experience with this 2.0L engine in a 2019 Lexus UX 250h. The confidence grows.I'm a big fan of this 2.0 engine. I was happy to see it become standard on the corolla for 2023. Makes the LE a really strong value proposition.
Thank you RDY4WAR.You can't ask for a much better report than that. Keep doing what you're doing.
