I get a lot of VW injectors with flow issues but not many Toyota's, the cars that get the most use seem to have the least amount of issues.
It spent its last 100k miles in California and their reformulated "stuff" they call gas.
But for the majority of the close to 300k miles from April to November it saw normal fuels. We used to have OXY fuel Nov 1st till April 1st.
The fuel here is now up to 10% ethanol except the "clean" fuel at some stations which is premium only.
Agree that driving a vehicle is MUCH better than it sitting ( sadly something that my 2004 GMC does) but if you are putting so much "bad" fuel (which some members here call anything other than top tier "bad") through the injectors would not I see deposits and other drive ability issues?

I once filled up at a clean looking gas station without a name brand, in the middle of nowhere and literally as soon as i felt the gas station, my engine was bucking and shuddering, not able to rev past 3,500 rpm (Limp Mode) with a Check Engine light.
I had to Limp it for the next 300 miles, fill up with decent gas, run that tank dry. Then i finally got home where i added either Redline or Amsoil fuel system cleaners for the next several tanks of gas as the engine slowly began to get back to normal.
I don't know what was in that gas, or whether it was even 93 Octane but after that incident that could have cost me my modified Engine, I only fill up @ 90% Shell and 10% other name brand gas stations.
Just my
But the ORIGINAL poster asking the question has a 2011 Corolla. Hardly something that NEEDS premium.
So ALL of our comments should be answering HIS question.
Also another reason why I stay away from vehicles that NEED premium.
I'm sure getting bad fuel is something that happens here and there.
Thankfully in your case it did not cause any damage. And when on the road its hard to know what is doing a lot of sales. Back in 2009 we drove across the US (almost 6000 miles in 15 days) and everything I bought ran fine.
And trust me the Subaru would let you know if you got anything less than good. It would ping at times with a little shake at idle.
Take care, bill
