18 Lexus GS350, 44K on ODO, PUP 5W20, 8,400 OCI

[chinee]

Here we go again with another boring post... This fill is mostly PUP 5W20... 5 qts PUP 5W20 and 1.25 qts of PP 0W20. Replaced with PP 5W20.

UOA looks good, nothing truly standing out. At this rate I will likely have this car with me for another 10 years.

Fe wear rate is coming down nicely. Other metals are just low noise.
Contamination low. TBN decent. FP and Vis good.

10k miles is a no-brainer.

Looks good, these engines seem to last a long long time.

Your cSt Viscosity of 8.6 didn't seem to move during your entire 8k+ OCI. Are you sure this wasn't originally 5w30?

10k would be a nice round number. Silicon dropped in half, with similar miles, from 1/29. Nice report on this Lexus & thanks for sharing.

Pretty sure it was 5 qts PUP 5W20 and 1.25 qts of PP 0W20.

I agree... the numbers have come down quite a bit. I will likely run to 10K on this fill of PP 5W20.
