The 2.7L spec for the Colorado/Canyon and Silverado/Sierra is being updated. The correct spec is 5.7L/6.0 quarts for both the aluminum pan and plastic pan. The spec for the 2.7L in the CT4 has not changed.
When I use 5.5 qts in aluminum pan 2.7 Silverado it reads 1/2 quart low on dipstick. Always check oil after changing oil to prevent customer coming back with oil consumption concern.
