It’s important to keep a record of when you last changed the car oil. Some diesel engine oils appear to be pretty black a couple of days following an oil change whereas the engine oil in hybrid vehicles will look almost new even after 10,000 miles of service.  In extreme dusty and sandy conditions it advisable to change your oil 1,000 miles to prevent premature wear. The dirty oil becomes a liability for your car and can shorten your vehicles service life. By changing your car oil frequently, you may greatly extend the engine’s life and even increase the resale value to a future prospective buyer.

Changing Engine Oil Under Extreme Operating Conditions

First, let’s define extreme operating conditions. You are under an extreme operating condition when you do a lot of driving in the city and frequently do stops, going on again to hitting the road. A brilliant example would be the rush-hour traffic where your car experiences stop-and-go driving on the road. Another definition would be making multiple short trips and leaving your car running while parked on a hot day with the air condition cracked to the max. These trips never allow the vehicles even to full heat to operating temperature and can build up engine oil sludge over time.

Other reasons for increased oil changes involve towing another vehicle and super hot temperatures that exceed 100 degrees F. When either of these extreme conditions happens to you, you must change your car oil as often as 1000 up to 3000 miles on the older vehicles. For new cars, there are recommendations made by the manufacturer that should be followed under extreme car use.

Changing Engine Oil Under Optimal Operating Conditions

A car oil change can also vary on the recommendations of the car manufacturer. Some manufacturers suggest that car oil is changed every 7,500 miles or more depending on the optimum operating conditions. The obvious perks of having a newer vehicle are their ability to operate longer with the use of new synthetic motor oils. More recent research has produced motor oil of which efficiency is extended and some oil brands claiming that you only need to change your oil once a year. You might want to change your car oil for every 5000 miles or every six months depending on which one comes first, to be safe.

For less service-minded drivers, who frequently drive on the freeway and long journeys with high-speed driving, extending the interval changing your car oil can be considered, but for the new vehicles only. It’s still best if you don’t go over 5,000 miles to change. Under no circumstances should you fail to follow the recommendations made by the manufacturer for car oil change interval.
