The gas I'm buying is over 5 months old.....

[SHOZ]

I've been getting my 93 octane and a Mom and Pop no name (use to be Phillips66) gas station. They only raise the price when they get a new load. The last price change was mid November of 2017. The price is $2.89 and cheaper than some regulars around.

No problems with using it though and my gas mileage is higher than ever.

 

[Smokescreen]

Probably the only honest gas station owners left anywhere. I would reward that honesty with loyal business.

Underground tanks, so temp of gas is kept low? Low loss of the lighter fractions. Not sure it'll be much of a problem then.

 

[ARCOgraphite]

Did you ask them when their last delivery was or are you speculating?

But, If its good its good though!

I got GARBAGE gas right next to a BMW and MB dealer a few years ago.

Premium. Barely made it home.

Gas can be problematic around here.

Touch it with a smidgen of Star Tron

 

[SHOZ]

It's in a small town with a half dozen stations and truck stops. They will keep their price the same as all the others are gyrating up and down. I just figure they are on a pay me before I dump the fuel plan, so they only change the price based on the last fuel dump.

Yes underground tanks and all stations in Illinois have upgraded to plastic tanks over the years.

Star Tron, I'll have to look at that. Pretty concentrated formula it looks like. I do add a bottle of Gumout One and Done in about 7 gallons of gas once a year.

Their price for 93 octane is $2.89 and the rest in that town are $3.25-$3.35, 87 octane they are $2.67 (just went up last week) and the rest are $2.59-$2.62.

I hope the fuel is ethanol free. If the fuel contains Ethanol, 5 months old can be a real problem.

 

[SHOZ]

No all gas around here has ethanol. No problems with how the car runs and it's getting great gas mileage. No top tier station too!!!!!

I can see how their gas can get that old as when other stations around are fluctuating their prices all over the place, including DOWN, this station sticks to that one price. Regular-grade gas has been varying between $2.25-$2.65 for a couple of months so if one station stuck their price at $2.89, they're gonna look 'bad'.

I'm not sure that their system makes sense long-term. Given most stations get fuel deliveries at least weekly, this station isn't selling a lot of gas.

 

[SHOZ]

I usually go to the cheapest place to get gas. They have been my sole station for premium since 9/2017 except for two times. I usually fill up once a week. Everyone else is around $3.25 around here. W G is the staion.

Youre fine.

Oil and derivatives are only good for about six months from the well, so you are at the edge there. The problem is bacteria eats petroleum, and the bacteria is present at the wellhead, so everything is contaminated with it. Stored oils can get by because there is little to no air present in an unopened bottle, but fuel in a tank has a lot of oxygen exposure.

The bigger problem is probably that you are using winter gas, which has more aromatic compounds that evaporate better in cold ambient temps, which helps cold weather starts. So it's no surprise your fuel consumption is up in warm weather, some of what you are buying is gassing off while in a non-full tank. Things should settle down a bit when they get their next tanker fill of summer gas.

The fuel system cleaners are added either in the tanker when it fills at the refinery or is added when it fills the bulk tank by the driver. Generally speaking low cost fuel outlets don't buy it (it is expensive, relatively), relying on the base formula as it comes from the refinery. So you probably aren't getting whatever benefits they offer.

Bacteria in any form cannot live through the refining process.

No, no and no. Gasoline is not affected buy microbial growth. Diesel fuel is. Fuel system cleaners are not an option for the gas station to choose. It is epa regulated and frequently tested. It is added at the distribution terminal.

 

[SHOZ]

Their premium price went up yesterday to $2.99 a gallon. Me thinks they are just cashing in as everyone else in town is still +$0.30 a gallon more. I don't blame them.

 

[Olas]

If you're really concerned do two things.

Dispense fuel into a fuel can to take home and observe
Pour from the can to a glass
Allow to settle, then observe,

Water will form an obviously seperate layer.

If no water is present, add some xylene/toluene/benzene/isooctanol to restore lost octane and use it up.

I bet they are lowering the pump price as their inventory gets old, to get rid of it faster. So they are raising the price when a fresh load is delivered. What's important is their intent for changing prices, that is what I am drawing attention to with this comment. Also maybe I'm not explaining it right, I'm kinda stupid sometimes... there's a fine line between genius and insanity

I don't think they sell a lot of premium. Going to get gas tonight and see if it's changed again.

 

[SHOZ]

Still $2.99. Mileage was up to an even 34 mpg. Amazingly the same my dash indicator was showing. It usually over estimates.

87-$2.67
89-$2.77

 

[SHOZ]

They just raised the price of 93 octane to $3.19. 87 is $2.69 and 89 is 2.89.
