This is my latest and sadly last UOA. Truck has been lost to a tragedy but this shows the past 2 UOAs of rough service on Valvoline Synthetic 5w30. First report was VWB at 5k oci
This may be the finest syn I've ever used...great TBN retention...smooth as silk and didn't use a drop. It saw cold starts as low as -41F and as warm as 100F. Lots of idle time and lots of towing. Truck had an aggressive tune as well...
