This is a customer of mines truck. Its a 2010 Silverado with a 5.3 in it.. He drives about 50k miles a year. This was over like 4 months he put 16k+ on the truck. We installed a EA15K50 filter on it... Previously this truck has only had conventional and Walmart Fram filters every 3k miles. I used the new KIT14 UOA kit. It gives very basics. But as you can tell with viscosity being slightly higher than virgin viscosity, there is no fuel dilution present. Also the fact that wear metals are low I'm sure oxidation is low.

Yeah.. But this truck also gets ALOT of idle time at job sites. Is driven in severe traffic at rush hour commonly.

About the same except iron about 22 and copper about 34. Viscosity would be down to 9.2
