This chart assumes 6 mpg (2.5 km/L). Your distance maintenance intervals may need to be adjusted if actual fuel consumption differs from the average fuel consumption Caterpillar considered.Example: Your 3406B rated 350 hp (261 kW) at 1800 rpm is averaging 5.5 mpg (2.3 km/L) due to high load factor operation. The engine consumes 2500 gallons (9500 L) of fuel to travel 13,750 miles (22 000 km). PM Level 1 should be performed at every 13,750 miles (22 000 km) instead of 15,000 miles (24 000 km) shown on the schedule.1Experience has shown that maintenance intervals are most accurately scheduled on the basis of fuel consumed. Rated engine speed and load factor are also important for some components. However, Caterpillar recognizes that the distance (odometer) interval is most commonly used to schedule maintenance for on-highway vehicles. 2Replacement with genuine Caterpillar Remanufactured components offers the best value to truck engine customers.NOTE A: Remote mounted or auxiliary filters require additional oil. A 13 quart (12.3 L) supplemental oil filtration system extends the normal oil and filter change interval to 16,500 miles (26 500 km). When changing oil, overfill crankcase by amount needed for auxiliary system (if equipped).To prevent crankshaft and/or
