Information on 3.4L V-6 Engine Oil Capacity

This bulletin is being published to advise technicians of a change to the engine oil capacity. The engine oil capacity with filter is listed in the 2005 Chevrolet Equinox Owners Manual as 4.5 quarts (U.S) or 4.3 Liters (Canada). This is being revised to an initial fill of 4.0 quarts (U.S) or 3.8 Liters (Canada), (approximate) with filter and top-off as necessary. The 4.5 quarts (U.S) or 4.3 Liters (Canada) recommendation was an initial volume fill for a completely dry engine at the assembly plant. The change in oil quantity will not be realized in the field by the customer during an engine oil change.
