This maybe needs to be a sticky. Also posted this on g35driver.com http://g35driver.com/forums/lounge-o...ium-pumps.html

Yesterday I went and filled the car up from a gas station I used before. The car was past E and I got half a tank of 93 octane. I DIDN'T turn the car off. After a couple of minutes of driving I noticed that it was somewhat sluggish unlike before when it was on E. I suspected the octane rating right away even though my car has an Air/Fuel sensor that is out which is expected at the mileage.

Considering I paid almost 3 ****ing dollars for 93 and POSSIBLY got 87 or maybe even 85 I kinda want my money back.

I search a bit and found this.

"The first time the driver was told to move 85 octane to the 87-octane tank, he said he "looked at the trainer and said, 'You can't do that, that's downgrading, that's contamination.'"

"11 News identified a total of 16 gas stations across Harris County. For instance, at the Conoco station at 13102 Bissonnet, records show 700 gallons of regular unleaded were dropped into the super unleaded storage tank on Oct. 17, 2009. At a Phillips 66 at 8203 Fondren, 1,000 gallons of regular unleaded were poured into higher-octane tanks on Oct. 10, 2009."

 

 

sooooo where would you fill up then? Or is there no way around it?

 

Wish I could get 93 octane for $3.00 lol.

 

Doesn't really seem like there's much you can do about it unfortunately.. :\

Thanks for sharing though

 

You can get an octane tester but I think it's expensive.

This isnt new news... its been going on for years. Stick to one gas station... if your pumping gas somewhere else dont fill up only put 1/4 to 1/2 a tank if possible.

 

You could if you moved to Jersey, lol.

I pay $2.70 for 93 octane!

 

Well with all the BP spilled in the gulf... You'd think gas would be cheaper in FL.

 

Wonder if you could get your investment back by sueing or rather threatening to sue the gas station passing 87 of as "Premium"? joking.....sort of.... fricken bastards

 

in for the data logs showing retarded timing due to knocking from low octane.

 

Really? I didn't notice that on my latest fill up? What gas station in Ga?

 

..even the quotes in his post reference dates in 2009. I've heard of it too..

 

 

I had a gas station down the street from me selling gas with no ethanol(93), so I filled up there a couple of times, but my car always ran funny. the last time I stopped when I needed to get gas quick, it was now only 91 octane. I'm pretty sure that's what they sold me the last 2 months, and the price never changed either(2.99/gal)

 

Pretty sure this has been going on ever since multiple grades have been sold...

 

that's why i use only shell gas. too much reputation for them to ruin it with some BS like this.

 

I remember when I was a teenager working in a Mobile station we ran out of regular and the owner pumped 300 gallons from the premium tank into it? I do know that when refining gas they target a minimum octane rating, that said it's possible regular 87 may be a little higher than 87. The sump of fuel tanks at gas stations actually loose suction with 300 to 500 gallons left in them so this does happen where they put regular in them hoping that the remaining premium fuel sweetens the regular fuel enough. Maybe they should go back to color dyed fuel again...

 

I used to use literally 2 types of gas stations, but I noticed I would run through the tank faster with one or get slight pinging at times with the other after a full up, I switched to Shell and am going to stick with that, been good thus far. I usually avoided them since they were slightly higher than other stations but you get what you pay for. There's not much room for error if your tune is borderline/tight with lower than normal octane.

 

This has been going on for literally decades. When I was in high school my buddy had a job pumping gas at night, and his boss used to give him an envelope with cash in it to give to the tanker driver with instructions to fill the regular tanks and dump whatever was leftover into the super tanks.
He would then have an envelope for the state regulator to "overlook" the degraded super fuel when inspection time came.

I know laws are alot tougher now but $ always rules.
