So my goal was to try and stretch Castrol GTX HM to 10000 miles in my Ford Transit 250 with the 3.5 GTDI and 12 quart oil capacity.
I still haven't gotten the VOA back from the batch of oil I used for the change but the fact that the viscosity is out of grade is alarming.
Thoughts or suggestions? Thanks![Beaming face with smiling eyes :grin: 😁](https://cdn.jsdelivr.net/joypixels/assets/8.0/png/unicode/64/1f601.png)
