Semi-Synthetic 4-Stroke Outboard Engine Oil SAE 10W-40 – 4L

Your outboard runs hot, you push it hard, and the last oil broke down faster than it should have. This 4-litre semi-synthetic, SAE 10W-40, is a Japanese-formulated premium grade built for 4-stroke Yamaha, Suzuki, Honda, Nissan, and Tohatsu outboards that see sustained load. The thicker 40-weight film holds up in high-heat, high-RPM conditions where a 30 thins out. One bottle, one full service, no second trip to the boat ramp
