If you didn't mention it to them, how did they know to tell you to switch back to 87? There is no way to test the fuel in a car.
Please stop directly associating the stalling with the octane, that is really foolish.
The 89 doesn't cause stalling, bad gas does. You got a bad batch of gas and that is what is causing the stalling. It is not the octane so please stop associating the engine stalling from you using the proper octane for the engine.
Go get some water remover and put it into your tank to remove the water and fill up at a GOOD station, not a mom and pop gas n go at the corner.
In tough times, most people won't even use 89 and it will sit in the tanks for longer periods which will have it go bad or collect more water.
That is your problem, not the octane. 1000s here use 89 and we have NO problems.
