Synthetic in AT?

[timbuctoocal]

I decided to have my A/T "flushed". (2nd flush and now 152K)
The service will not be done at mitsubiti.
Big O Tires will do it.
I notice their sign states its a synthetic or synthetic blend.
Any advice ?

Ill reschedule once I get an answer that tips me one way or the other.

What year do you have? if it is not a 98 or older then you should stick with the mitsu oil.
