One-third of college students who had a car on campus last year said they should have changed its oil more often, according to a recent online survey.

The poll found that 32 percent of students who changed their oil two times or fewer during the last school year said they meant to change it more often, but simply forgot. Nearly 18 percent cited their busy schedules and 15 percent said their lack of money prevented them from taking their car in for an oil change.

Fifteen percent of the students said they thought someone else was going to take the car in, but it never happened. Reflecting back, another 20 percent said they didn't know their oil needed changing or that it wasn't necessary to have the car serviced at the time.

"While most students changed their oil at least once during the school year, many of them acknowledge that they don't keep a regular maintenance schedule," said Anne Tawney, vice president of marketing at Jiffy Lube International, which sponsored the poll. "With the new school year starting, it's a good time to remind students about the importance of keeping their cars in good condition. Routine maintenance is the easiest way to prevent a costlier breakdown later on."
