Dallas Engine, Transmission, and Differential Oil FAQ

1. How Do I Schedule an Appointment?

Once you select the service you need, AutoNation Mobile Service will help you find a date and time that works with your schedule. 

2. What Should I Expect From a Service Appointment?

On the day of your appointment, our mechanic will contact you when they arrive at your location. Depending on the work area, our mechanic may move your vehicle to a more appropriate location on site and they’ll get to work. Once service is complete, our mechanic will contact you, go over a comprehensive report on your vehicle, and answer any questions. They’ll process payment for the service and will be on their way. 

3. When Should I Change My Engine Oil?

Typically, an older car needs you to change its motor oil every 3,000 miles. However, a newer vehicle or a car with modern lubricants may have a longer oil change interval — likely at every 5,000 to 7,500 miles.

Every manufacturer has different recommendations for when you should go for an oil change. 

To find out, you can always take a peek at your owner’s manual.

Alternatively, if you have a newer vehicle, you can keep an eye on the oil change light on your dashboard. It should give you an indication that it’s time to get your motor oil changed.

4. How Urgent is Changing Transmission Fluid?

Since transmission fluid lubricates your transmission and keeps it from overheating, you can probably deduce what is liable to happen when you don’t have adequate transmission fluid. That’s a surefire way to cause irreversible damage to your transmission.

5. Is Transmission Oil the Same as Differential Oil?

No, they’re not. Transmission oil (or transmission fluid) is used in automatic transmission vehicles, while differential oil (or gear oil) is for manual gearboxes.
