5.7 2012. I am running 5w20. @97000 milesNapa synthetic. The gray bottle. Use 89 chevron gas.
No towing. At 5000 miles oil getting darker but rub between fingers and not gritty. Still very slippery. Mechanic told me that cam advance uses oil pressure, so not to change to 5w 30.
The pressures have been like between 1 to 2 different between 5w20 and 5w30. The difference between hot and cold oil can be much more. We have guys running 40 weight in the 5.7 w/o issues, not my choice but they are doing it.
