The A26 is the first engine in the industry to meet rigorous B10 design life standards for an unsurpassed 1,200,000 miles. The B10 designation requires that 90% of engines meet a mileage standard – typically 1,000,000 miles -- before the cylinder head or oil pan is removed for a major repair. Most competitors use B50 standards that require only 50% of engines go 1,000,000 miles before a major repair. Only the A26 meets the B10 standard for 1,200,000 miles. If your trucks are averaging 60,000 miles each year, that’s the equivalent of running over 3 more years before your first major overhaul – real savings that impact your business
