So Up until last week i always used high test or premium gasoline.
then i was speaking with my brother in law who said with high prices of gas no-one is using or paying for premium so it sits and sits underground.
I think he is right. you should have seen the crud that came out of my tank and I had just drained it completely when i replaced the petcock. within 4 fillups it was filthy brown and nasty.
I for one will now use regular

I could see possibly an ounce or two 'left over' but a full 1-2 gallons?  I am suspecting that the typical pump that is in place these days is more efficient than that.

Slightly off topic, so forgive the highjack, but I've been wondering about new gas stations. Around here they pop up all the time. Is there anything to be concerned about regarding sealants, liners, general "crud" in the new storage tanks that I should wait a while before filling up at one of these new stations? There's one about to open near my house, fresh tanks in the ground and everything. It's sat through the rains that drifted our way from Gustav and Ike, so I'm worried about water too.

No way to fact check this guy, but here is a post from another forum reporting a case like you describe:

End of Aug 06, I filled up my car with what I thought was 10 gallons of Sunoco 94. My car requires good premium. The car died 1 mile down the road. It was flat bedded to the dealer and we found that I had actually pumped in 10 gallons of water! Turns out the station/convenience store routinely had this happen after a rain storm. The fill caps for their tanks allowed rainwater to rush in!
Cost me $1250.00... after a couple of weeks of round and round, including filing reports with the PA DEP , Attorney general and the BBB, i finally got them to admit they had a problem when I showed up at their place with a camera while the crews were repairing the fill cap area at the store/station.
I got a check the next week.
I have a safety system on my car for bad gas, alcohol injection. It protects me from bad gas... but not a tank of water.
I'd love to see regular testing of octane.... the engine it saves could be your's!

The thread is along the same lines of octane testing. The whole thread is here:

3 lines come up into the Box we call teh pump. Each passes thru what is called a computer, but its not at all a computer, but a mechanical metering/charge the customer for each unit of fuel/ "Computer". I dont know if these new pumps have one for ech fuel type. The Pump that sends the fuel is in each buried tank, Pain in the butt to change.
Certainly, with a change in grade being pumped, the contents of the hose will be what was last pumped. How much inside the Pump? To the plumbing where the different types ties together, so, UP from there, & all thru the hose is the last stuff pumped. ID on the hose is about 3/4 inch I think. A quart wouldnt seem too high of an estimate.

I was a maintenance man for a string of stores for a short time.Crazy the crap they wanted me to do. I stood on a 12 foot ladder, standing across the toolbox of my truck, tip toeing on the top of it, to change lights at a station,, twice, then told them No more, Imagine a "West Tx" gust of wind while I was stretched out like that?

Thanks for the info guys; and again sorry for the hijack. With such a small tank, I try to be careful about what I put in it. It's just not feasable to try to QC each station I use. I try to stick to the same ones around town; but out on the open road, it's any port in a storm. Of course the way my work schedule's been lately, getting out on the open road is more a fantasy than a reality.

  I'm sure that all gas hoses have filters in them,So I think you get pretty clean gas.high octane gas is like retarding the spark,so you will have less power if you use higher octane than you bike needs.

LOL.  Filling paper towels is a thing of the past too, along with the air hose.  I work for an oil company, and my company's franchises are the WORST.  Now we get ridiculous 50 cent compressors that can't blow up a balloon.  I drive a Ford E350 van for my work vanpool, and the only place I can get enough pressure to put 80 lbs in the rear tires is at a tire store  .  Today I stopped to get gas, at a branded station, only to find the moron didn't have card readers at the pump.  On top of that, I apparently had to pay first, because I could get nothing to work.  I packed up and left.  "Hello, 1979 called, and they want their gas station back."  Talk about hijacking a thread . . .
