How often should I change my oil?
I drive less than 1,000 miles every 3 months.
Should I still change it every 3 months?
I’d change it once a year. Every 3 months is way too frequent. Some here would suggest twice a year.
As long as you get the car fully warmed up once a month - 20-30 minute drive - once a year should be OK. If you just never drive that far, every 6 months.
