The chart is being updated with specs for engines with the aluminum pan and plastic pan.
2023 Sierra Doc 4956980 for L3B oil capacity shows 5.5qts with aluminum pan and 6qts with plastic pan. This chart only shows 6qts for L3B. Which one is accurate?
I agree with you Eric
Type and capacity should be on the same page. 100% of technicians would agree.
