HOUSTON, Texas – There was a time when changing a car’s motor oil at three months or 3,000 miles was a maintenance commandment, but consumers’ attitudes about changing their vehicles’ motor oil are shifting, according to auto aftermarket research by The NPD Group.  
 
In response to NPD’s 2012 Aftermarket Outlook Survey conducted in August, 51 percent of vehicle owners said they believe oil should be changed every 3,000 miles or three months, down from the 59 percent of consumers who held this belief in 2007.
 
Although the percentage of consumers who believe oil should be changed every 3,000 miles or three months has declined by 8 percent over the past several years, those who actually have their oil changed between 2,000 to 3,000 miles has dropped by 10 percent. Thirty-nine percent of auto owners responded to the 2012 Aftermarket Outlook Survey that they wait between 2,000 to 3,000 miles to have their oil changed, down from the 49 percent who changed their oil at this interval in 2007. Twenty percent of 2012 survey respondents change their oil between 3,001 and 4,000 miles, 22 percent between 4,001 and 5,000 miles and 11 percent over 5,000. 

Fifty-seven percent of car owners are guided to change their oil by their vehicle’s service indicator light, 31 percent by the next oil change sticker put in their car, and 10 percent keep track of the mileage and months on their own, according to NPD’s 2012 Aftermarket Outlook Survey.  
 
“The oil intervals recommended by auto manufacturers do vary now due to advancements in auto and motor oil technologies,” says David Portalatin, executive director, auto aftermarket industry analyst. “As a result we’re seeing a shift in consumer attitudes and behaviors in regard to changing their car’s motor oil, but still top-of-mind with consumers is the 3,000 miles or three months rule of thumb.”
