Recommended oil:

API classification SL with the words "Energy Conserving" (if the oil with SL grade cannot be obtained, it is okay to use SJ grade oil).

ILSAC GF-3 or the equivalent which is indicated on the container with the new API certification mark (Star burst mark).

NOTE: If vehicle is used in desert areas with very high temperatures or for other heavy duty applications, the following viscosity oils may be used: ILSAC classification: GF-3 or API classification: SL
SAE Viscosity No.: 30, 40, 10W-50, 20W-40, 20W-50.
