Some people drive more than others, drive through more mountains, never take trips over 10 miles, and have other driving habits that constitute severe use. Severe use oil change intervals are often 2,500 to 3,500 miles sooner than regular oil change intervals.
Autocare.org recommends changing the oil every 3,000 miles if your driving falls under the severe use category. Always check your owner’s manual, and if it doesn’t have a severe use schedule, change the oil every 3,000 miles or three months, whichever comes first.
The additional strain on the engine decreases the oil’s lubricating properties and increases foreign substances in the oil faster.
So, what is severe use, and why do you need to change the oil more often?
