The recommended engine oil for a 1993 Chevy Blazer is 5W-30. While using 10W-30 oil is generally acceptable in most conditions, it may not be the best choice for extreme weather conditions. Thicker oils, such as 10W-30, can be harder to pump and circulate in cold temperatures, which can lead to increased engine wear and poor fuel economy. Using the manufacturer-recommended 5W-30 oil will help ensure optimal performance and longevity of your engine.
