By all means you can mix the two grades of gas, but it's recommended that you use 89 octane. from the owner's manual FUEL REQUIREMENTS 2.4L Engine All engines are designed to meet all emissions regulations and provide excellent fuel economy and performance when using high-quality unleaded regular gasoline having an octane rating of 87. The use of premium gasoline is not recommended, as it will not provide any benefit over regular gasoline in these engines. 3.5L Engine The 3.5L engine is designed to meet all emissions regulations and provide satisfactory fuel economy and performance when using high-quality unleaded gasoline having an octane range of 87 to 89. The manufacturer recommends the use of 89 octane for optimum performance. The use of premium gasoline is not recommended, as it will not provide any benefit over regular gasoline in these engines.
