384 MAINTAINING YOUR VEHICLE Change Engine Oil Road conditions as well as your kind of driving affect the interval at which your oil should be changed. Check the following to determine if any apply to you: • Frequent short trips where the engine does not achieve full operating temperature (operating temperature defined as 190° F (66° C ) coolant temperature). • Extensive engine idling (over 10 minutes per hour of operation) at ambient temperatures less than 32° F (0° C). • Driving in dusty conditions. Never operate the engine with oil level below the "ADD" mark or above the upper "SAFE" mark. • Frequent trailer towing. • Taxi, police, or delivery service (commercial service). • Off-road or desert operation. • Extensive operation at high engine speeds (greater than 2900 rpm) and loads (greater than 70% throttle).
