Best Answer

My owners manual recommends premium for optimum performance. I alternate between premium and regular. If you repeatedly use regular with 87 octane you might notice knocking when travelling uphill. My owners manual recommends Plus with an octane rating of 89. For improved performance it recommends premium with an octane rating of 92 or higher. NEVER use Regular with an octane rating of 87.
