Lexus IS 250/350/300h Engine Oil Spec Malaysia — 5W-30 vs 0W-20 Explained
IS 250 (2GR-FSE 2.5L V6): 5W-30 full synthetic, 6.4L capacity, every 10,000 km. IS 350 (2GR-FSE 3.5L V6): 5W-30 full synthetic, 6.4L, every 10,000 km. IS 300h (2AR-FXE 2.5L hybrid): 0W-20 full synthetic, 4.4L, every 10,000 km. The 2GR-FSE uses both direct injection and port injection (bi-injection) — while this reduces carbon buildup significantly compared to pure DI engines, valve inspection is still recommended at 100,000 km. IS 250/350: the V6 has a 6.4L capacity — some workshops underfill with 6.0L, always verify with the dipstick. The bi-injection system requires clean oil; never run past 12,000 km on full synthetic regardless of oil life monitor. Recommended: Toyota Genuine 5W-30, Mobil 1 5W-30, Castrol EDGE 5W-30. Specialist cost: RM 380–620.
