Tech Tips

*1: Weight shows the figure with oil and coolant fully filled.

*2: Premium unleaded gasoline with a research octane number 95 or higher required for optimum engine performance. If 95 octane cannot be obtained, you may use unleaded gasoline with a research octane number as low as 91. Use of unleaded fuel with a research octane number lower than 95 may result in engine knocking and significantly reduced performance. Persistent knocking can lead to engine damage and should be corrected by refueling with higher octane unleaded gasoline.

*3: Emission regulations deffer by country and region.
