|---|---|---|---|---|
| Base | API - SAE 5W-30 | 7.50 QTS. | — | Use oil that meets GM Standard GM6094M. API - SAE 10W-30 can be use if SAE 5W-30 is not available and if it is going to be 0Deg.F (-18Deg.C) or above. DO NOT use other viscosity oils such as SAE 20W-50. For areas of extreme cold, where temperatures fall below -20Deg.F (-29Deg.C), it is recommended a SAE 5W-30 synthetic oil or a SAE 10W-30 oil.
