I was told years ago never to fill up at a gas station that was filling up their tanks. Is this true. I was told it stirs up all the junk in the in ground tanks. Any thoughts?

Look at the size of the hose going from the tanker to the underground tank. do you think there is a possibility that hundreds of gallons of gas going into the stations storage tank could stir some crud up? I do.

I know they put filters on the gas pumps at the station. So there is a system in place to catch the crud. there is also a possibility the tanker just left the station ten or two minutes before you got there.

But if you do not need gas, why risk it?

In the overall scheme of things this is not one of my concerns..Just get gas from a heavy pumper and you are fine..

I owned/operated a Gulf gas station in the early seventies.. Had small tanks compared to todays monsters.
The delivery truck used to stir up some terrible looking bottom crud!!

Bob....in stating that, how often if ever do they....the owners or the gas industry ...Shell, Chevron, Sinclair etc. pump out and actually clean all the debris out of the tanks? Are they mandated by state or federal to do so every 5 yrs. or so or does it just keeping collecting and hopefully caught by the filters?

I don't think there is a law requiring tank cleaning. It would more than likely be whether the fuel can be certified to sell when tested. If it don't pass a certification test, tank cleaning may need to be done by the station owner so the gas is legal to sell.

Stations now may have their big signs that say Gulf or speedway or Sunoco ,But they don't have to sell that gas only have their oil products on their shelves! We have Blodget oil , and Coyn oil filling all the tanks around here in all the different named gas stations out of the same trucks on the same days! The last actual Co truck I saw in this area was Clark and that was about 10 years ago! That station is now an imperial and is filled by Blodget oil co and Blodget bids on fuel and get it from any refiner or supplier

We used to stick our tanks to check on the water levels in the tanks and have the water pumped out! There is a safety margin bellow the pick up! and if there is no water, there is unsalable gas in this safety margin! Now when a station sells all their gas and their down to the bottom and want that hidden gas trapped in the safety margin, owners pump water in to raise the gas level so the pump can pick it up and leave the water at that level! A reputable dealer or owner wont do this, but you never know who the ones are that do:confused: So when new gas is added it stirs up the crap on the bottom and it takes time to settle :pain:

There is no more regulation on octane either. the octane rating on the pump isnt factual to what your pumping! The government used to check octane and put Government inspection stickers on the pumps that the octane was tested and when, and is up to snuff ! Deregulation stopped this practice the only thing that's tested now is the money per gallon count on the meter!! and you cant trust that either. You ever hit the trigger on the pump and the split second before the pump kicks on the meter count jumps to 10 cents or over LOL:D! Thats an extra ten cents per car doesn't sound like much but it adds up!

I dont know if other states are like michigan but as for government regulation Im sure they are!

Actually the operator Is supposed to stick the tanks and when water reaches a certain level the tanks are pumped to the bottom and fresh fuel is put in the tank..Does not happen too often we hope but we did do that when we needed to..The fuel that was pumped out went back to be filtered and processed and put back in the dist system..

Back in the seventies we didn't have the Fed and state regulations. Used to "stick" the tanks and check for water..

Gulf oil was my only supplier, by contract, back then.. Totally different now.. All maintainence was up to owner

Station was removed about 12 years after I sold it.. Premium tank was leaking underground..

Citgo is the only supplier around here that demands total controll of your tanks.. Marathon and Sunoco are the biggest area shippers..

That turned out to be extremely informative for me thanks for all the responses. I learned a lot from what I thought was a silly thread I started. I do notice a difference in gas mileage from tank full to tank full if I am traveling so now I know why.

You and me both! HOLY COW now I don't want to go to a gas station at all!

I've worked for 2 major oil co. and know for a fact that nothing that Jester said is true around here. Each oil co has there own addative package that is required by law. You cannot mix water with todays gas because of the alcohol content.

You are right, I remember seeing those stickers and I don't think they are there anymore!

Boy that would really stink if you think you are getting 93 and actually getting 87. It could cost you an engine I would think.

I've got 19k+ on my rod and regularly drive the back roads and fill at what ever stations we run into. No problems except Wisc and IA. then only once each...and they were not show stoppers, only poor quality gas. I don't think that there was water in it as there was none in my carbs.

I still don't have any filters on my fuel system and there is no trash in the carbs.

Same goes for diesel. My truck gets a fuel filter once a year now and it is usually still pretty clean. These get black especially from the bio diesel. I have even check the semi filters that get changed at the shop. they get a lot more miles than I do and they are pretty clean too.

I think the gas and diesel here in Minn is pretty good. Other places not sure.

It may be true that the Feds do not regulate quality or octane level, but many states do. This is an area that the Feds dropped because so many states were doing it, so it was doubling up on the process. Some states are way more stringent not only about quality, and octane rating, but also accuracy of the metering.
As for filling when the truck is there; what's the difference if it just left and you don't see it there? You get the same result. Pumps have filters, as do our cars. Mine are set up with pre and post filters, so I'm not too worried about anything but clogging my filters with whatever the pump filter doesn't catch.

In Michigan there was regulation on quality but through the years the people who did it have all been down sized to the point of "0"!

Filters may catch debree and the sock in your tank may stop large debree. But water and other liquids still come through the pumps at the stations! we have one convenient store station close to where Im at that no locals go to, because of water, but its close to the expressway so they get a lot of traffic! I wont even get a gallon for my lawnmower there!

Alcohol draws water like a magnet, so I don't understand what you mean by you cant mix water with the gas now?:confused: Put gas in a mason jar add some water and shake it, it mixes and over time the heavy water settles to the bottom!! but with alcohol the water mixes even better and takes longer to settle! Dry gas is alcohol and draws water to it and breaks up the water molecules mixing it into the fuel instead of the water setting in a puddle in your tank! so it can be burned in your combustion chambers and doesn't cause damage to injectors ,Etc etc! A private owner of a station that owns his own pumps that buys his own gas only has to sell the oil products on his shelves to put up a sign that advertises a particular gas co. If a station is supplied pumps by a particular co. he has to buy and sell gas from that co. and is dictated the price he has to sell for if he sells different gas the company will pull his pumps! If you buy and and sell Sunoko your gas has all the additives ! But its getting to the point that you cant trust the sign out front of that convenient store station. Coin oil delivers out of the same tanker to Imperial, Marathon, and the Bp, on the same day they are all right in a row just a block away from each other. The tanker is void of company Logo. Coin oil thinks its funny because people think they are getting better gas mileage from the Marathon then the Imperial but its the same gas!!! I go to coin to get my 110 octane in gas cans and we talk about this! but the Sunoco station gets its gas from Sunoko

Unscrupulous Gas station owners don't add water so it mixes with the gas they add it so it stays on the bottom of the tank in order to raise the gas level to the lowest height of the pick up for the pump! The draw back to that is that when gas is added to the stations tank it stirs up the water and if you buy gas right after the tanks are filled the water hasn't settled yet and you may get water in your tank! Your statement about nothing I said is true is true in the areas Im familiar with and if alchohol has changed over the years I havnt heard about it!:confused:

Gas pumps used to have dated certified Federal inspection stickers on them with minimum octane being pumped on the sticker! Next time you pump your gas look for a state or federal or Howdy Doody inspection sticker on the pump! with the date of the last test and post it on this thread or better yet post a picture!!!! The last sticker I saw was 15 years old!!!! If you think I dont Know what Im talking about fine!:D

It happens, It has probably happened to many on here that fill up with premium and a few miles down the road have spark knock or you get a few gallons of gas and your engine light comes on and when you cap your tank off it goes out(any one have that happen)that's why I try to buy at a station I trust!! most high performance car owners have their particular station they trust! :mwink: If I pull into a strange town when on a rod run I look for a hotrodder and ask wheres the best gas is ! if I cant find one I flip a coin LOL:D

Octane used to be listed on the pumps as minimum octane I don't know now If the octane rating we pump is a max ,average or minimum rating?:confused: I worked for Texaco, Mobil, Shell, Gulf, Clark,And many others all over the world from time to time in my type of trade union 2 weeks at one plant a week at another a month at another etc, over many years I even stood guard on rigs in Arabia while in the Marines in the 60s before opac :pain: when we had leases on the land and the rigs were being attacked!:pain: I used to be up on changes But the last refinery I was in was Shell about 1988! So Im a little behind! My wife used to manage a shell station in Gaylord Michigan in the 90's and had to stick the tanks and when the water level was too high ( notice I said too high) there was water in the tank for weeks or months but was only pumped when it reached a maximum marked on the stick!!! at that time all stations only pumped when water reached a max allowable level marked on the stick!
