The busiest times are when the most people are calling this Fuel Doctor phone number (least busy times have fewer people calling). This high call volume does not necessarily mean that you will have a long hold time when you call. Companies like Fuel Doctor staff their call centers differently based on the time of day and day of the week, so you may experience a shorter wait on hold at the busiest of times. When we refer to the best time to call, we are referring to the optimal combination of lower call volume and shorter wait times.

The least busy day to call Fuel Doctor is Tuesday. The most busy day to call is Thursday. Again, this is based on a sample of 16 calls made with our AI-powered, web-based phone in the last 90 days.

The shortest wait on hold

We measured the shortest hold times to be on Tuesday. The longest wait in the queue on average occurs on Wednesday.

The best time to call Fuel Doctor

In summation, the best day to call Fuel Doctor is Tuesday. In this case, it's a no-brainer. Tuesday is not only the least busy day for calling this Fuel Doctor number, but it is also the day with the shortest hold times.
