GHG17 Medium Duty Preventive Maintenance Tables DD8 Severe Service Severe service applies to vehicles that average below 6.5 miles per gallon or that operate under severe conditions. Examples of Severe Service are idle time over 40%, load factor over 55%, operation on extremely poor roads or under heavy dust accumulation; constant exposure to extreme hot, cold, salt-air, or other extreme climates; frequent short-distance travel; construction-site operation; or farm operation. Only one of these conditions is necessary to categorize an application as Severe service. Table 25. 66 All information subject to change without notice.
