The recommended mileage intervals for oil changes depend on the type of oil used and the make and model of the vehicle. Here are some general guidelines for different types of oil:

1. Standard oil: Typically, standard oil should be changed every 3,000 to 5,000 miles.
2. Synthetic oil: Synthetic oil can last longer than standard oil, and manufacturers typically recommend changing it every 7,500 to 10,000 miles. However, it's important to follow the recommendations in your vehicle's owner's manual.
3. Synthetic blend oil: A blend of synthetic and standard oils, synthetic blend oil usually needs to be changed every 5,000 to 7,500 miles.
4. Diesel oil: Diesel engines typically require more frequent oil changes than gasoline engines. Manufacturers may recommend changing the oil every 5,000 miles or every 3 months, whichever comes first.

It's important to note that these are just general guidelines, and the best practice is to follow the recommendations in your vehicle's owner's manual. Additionally, factors such as driving conditions and the age of your vehicle may also impact how frequently you need to change your oil.
