Here is our latest tip for weaving through the phone menu to get to a real person the fastest: Calling this Tesoro Corporation number should go right to a real human being

Tesoro Corporation operates the call center for this 210-626-6000 phone number 24 hours, 7 days. The short answer is that you should call on a Thursday. This observation and the following section are based on analysis of a sample set of 65 calls made in the last 90 days using our free, web-based phone (see above).
An important note: busy times vs hold times vs best time to call
When we refer to busy or less busy times, we are talking about the volume of calls. The busiest times are when the most people are calling this Tesoro Corporation 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 Tesoro Corporation 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 time to call

The least busy day to call Tesoro Corporation is Thursday. The most busy day to call is Wednesday. Again, this is based on a sample of 65 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 Monday. The longest wait in the queue on average occurs on Wednesday.

The best time to call

In summation, the best day to call Tesoro Corporation is Thursday. This is not the day with the shortest wait on hold in the phone system, but we still recommend it for its ideal combination of low call volume and short hold times. Plus we believe that Tesoro Corporation staffs the call center well on Thursday.
Once again, please put this information in perspective because this phone number has no phone menu or long waits. It generally gets picked up right away if calling during their opening hours. If there is any way, it will typically be very short.
