What kind of gas should be used for 2000 Dodge Durango slt 5.9 engine 4x4?
The 2000 Dodge Durango SLT with the 5.9L engine requires unleaded gasoline with a minimum octane rating of 87 (regular). While it *can* run on 87 octane, using a higher octane (like 89 or 91) won't hurt it and might offer slightly improved performance in some situations, but it won't be necessary for proper operation. The owner's manual is the definitive source for this information.
