There have been a couple of these gas stations that have popped up locally. I didn't know how the quality was compared to most other gas stations like Chevron or Amaco. The prices are pretty low but I didn't know about the quality of gas that they offer.

 

Citgo gas is ok. I use it in my Max, only the hi-po stuff.

 

That's what I use also, never feels sluggish or anything compared to other premium grade gas.

 

Marathon sucks.
Bad gas, and some do not even have pay at the pump.

 

Citgo says 'Go'

 

I thought gas was generally the same quality. If they are different from company to company, what makes them differ?
