Car feeling gutless

Hi,
Car is with 4900 miles, oil changed at ~1300 miles.

Background: This week the car started feeling gutless, specially on low rpm. Less power than my 18 Brz, not able to break traction even in turns.

Did not hear any knocking event or any type of other engine noise that would call my attention.

What I am suspecting: bad fuel quality (filled with 93 from Kroeger this time)

Question: How do I diagnose if this is related to the fuel? Any other had similar reduction of power/torque?

Check your air filter, make sure you don't have a rat nest or something in there. Check your tail pipes, make sure someone didn't stuff a potato in there haha. Without a CEL or a Dyno it's hard to prove it's really down on power.

If the car is driving fine outside of feeling down on power I'd just keep going until half a tank and then fill up with a quality 93. I'd avoid hard driving until then. Ive experienced less than stellar gas at those discount stations.

Burn off gas refill from different station.

Drive through the fuel you have and fuel up at a different gas station?

This is not diagnosing, it is guessing. And will be done, as when I drive, fuel goes down

Another aspect to look at is the high temperatures and humidity around your area. But best thing to do at this point is to run all the gas and refill from a gas station that would offer a sort of cleaning additive in the 93 mix, like Mobil or Shell.
