Team,
First oil analysis I post here in more than 13 years.
- 2018 Silverado 1500, Crew Cab, Z71 with the 5.3L (L83) engine
- No idea what oil the dealer used, but should be 0W-20/Dexos 1 as recommended
- 5200 miles on the oil...21,520 overall
- First 3K miles was mostly long trips visiting family and moving out of state. The second half is completely different...short trips (commute is 3 miles round trip), 160* thermostat (yikes), and extremely dusty environment
- AC Delco oil filter
- K&N "cold air induction"...primary reason for analysis
Code
RICARDO: We found some fuel in this 0W/20 oil, but just a minor amount. 1.0% fuel is small enough to be
from normal use (e.g. short trips) or taking the sample before the engine is fully warm. With the viscosity
being well inside the 0W/20 range and wear looking good, you can be confident fuel hasn't caused issues.
Averages on the far right show typical 5.3L EcoTec3 wear after a ~6,700-mile run. Aluminum through
copper are the wear metals and they're actually a little better than we'd expect after a 5,200-mile run. No
issues stand out for this young Silverado.
