The recommended oil grade for a 2007 Chevy Impala depends on your location and the specific engine you have (3.5L V6 or 3.9L V6). You
must check your owner's manual for the most accurate information. The manual will specify the recommended viscosity grade (like 5W-30 or 10W-30) based on temperature ranges.
Generally, 5W-30 is a common recommendation for many 2007 Chevy Impalas, but using the wrong weight can damage your engine. Don't rely on online information; always consult your owner's manual.
