New to the forum, but been stalking for a while.
Since I run the Oil analysis program at work figured I'd run samples on my truck.
Seeing that the viscosity is dropping so fast, thinking i may look into trying a 0W40
sample on the 10th was a full run per the oil minder on the truck @ 5% remaining
sample on the 24th is 33 hrs, 1000 miles (10% per oil minder calculation)
Also decided to run a PC to see how decent or crap oem filtering is.
