Crap gas? Quick poll.

[eltren]

As premium fuel hits $4, even $5, yes five bux a gal for Exxon premium here in DC,
I am seeing even more traffic at the always-packed discount independents.

But...I've noticed my base Box does not like indie gas. It seems to run ok, but I'm pretty sure am losing 3-4 mpg when I use it. For real.

Which to me means the car is adjusting for a far lower actual octane level
by enriching substantially.

Is it just not that good, is it fraud?

Your experiences, knowledge?

Are you purchasing the same octane rating at each station?

[Stroked & Blown]

My Jeep threw a 'fuel quality' code the other day. I usually fill up at an unbranded station that is $0.25/gal cheaper.
Could be the sensor.
Filled up this week at Exxon and reset the code. We'll see if it comes back.

I stick to these gasolines whenever I can.

I always buy the highest octane fuel available.

Let me rephrase:

Does anyone here think that discount, independent, gas is inferior?

Why?

[Brucelee]

Yes, they are. I personally have had issues with Costco gas and as I suggested, stick with toptier gas. The additives do seem to make a difference in keeping your fuel system cleaner.
