My wife drives less than 5,000 per year. I use only 100 % full synthetic oil in her car. How often should I change the oil in her car?
Once a year should be fine with synthetic.
I’ve been doing this with my wife’s car and it is now 17 years old with 108K miles - 6300 miles a year average with one oil change a year. I did this with her 2 previous cars as well.
Agree with Mustangman. Once a year for oil and filter is OK.
