Is there any difference in the gas quality does anybody know?
87 OCTANE at Marathon here is like $3.07 and 2 BLOCKS AWAY
87 OCTANE at Shell or BP was like $3.23
Is their any difference in quality do you think? Will your car know the difference? I wonder if there are gas quality standards all the companies must meet? REGARDS!

im no master at this, but i bet it has to do with the difference in companies financial standings and oil stockpiles. there is a difference from station to station as far as purity but i think there is also a set standard
dont take my word for it tho lol

I actually get better mialage with midgrade than with low grade, but it does depend on the car. Some run better on low grade and some on premium. The thing with low-grade is it is not as clean and over time your pistons will get carbon deposits and your engine will start pinging.

True, but the original poster was asking whether there was a difference between two identical grades (both 87 Octane) priced differently at 2 stations.

I think the only difference of the two is like chevron adds techron and amaco adds stuff but can't think of it of the top of my head which help keep deposit out of your motor

Yes, essentially all gas you buy in the US is the same, and almost all cars are designed to run off of that basic 87 octane gas. More expensive gas just has more additives to help the gas burn cleaner with less carbon depositing in your engine. The difference doesn't really equate to anything tangible.

Chevron is definatley the best. You dont need to use it every time but i would say every fourth of fifth time you get gas you should get chevron. Just the basic grade is fine and it will def help your engine.

it depends where the oil comes from.
oil from south america (venezuela) tends to have sulfer in it.
try to avoid that.
citgo was run by the venezuelan state, but chavez changed the name of it.
dont remember what he changed it to.
only your really high end cars need to run off of 93,94, or 97 octane. for compression reasons, if im correct.

the higher the octane, the better the performance. It also burns cleaner. Race fuels and such are all very high octane. I put midgrade in my engine because I've had experiences with bad gas at the lower octanes. It also extends the life of your car/engine because its a cleaner fuel.

This is how I understand gasoline distribution works. For simplicity, there's only 1 pipeline.
In Houston, Company A puts 1mil gallons of 87 octane into pipeline. After that, company B puts 2 mil gallons of 93 octane into pipeline. Note that at the junction, there will be a mixture of 87 and 93 octane.
At the other end of the pipeline - in Miami, Company A extracts 1 mil gallons of 87 octane and Company B extracts 2 mil gallons of 93 octane. At the begin and end of their portions, there will be mixture.
The important thing is the companies doesn't have to wait for the physical gasoline they put into the pipeline to travel to the destination. Companies pumped x-octane gasoline into the pipeline and take out the same rated x-octane gasoline that someone else pumped in days/weeks before.
As you can see, all 87 or 93 gas started out the same. The cost difference is the cleaner (ie techron), marketing, and/or location.

Techron is a name that encompasses a bunch of crap that other refineries already put it.
Yes, higher octane is for higher compression engines. Do Not put high octane fuel in an engine that is not designed for it.
Yes, gas gets mixed in pipelines. So does natural gas, etc.
I'm telling you there is no difference between any of the major gasolines. I don't care what wikipedia says, or what you read in the media.

You would never be able to tell where the gas actually came from, so kind of a mute point.

Refining should remove all sulfer ect. The only real difference is the additives they put in there to burn out the crap in your engine. Cleaner injectors better air dillusion = better gas milage.
Dont buy crap from Citgo for the simple reason is that Chavez is a socialist nut!
