How much fuel is in that single hose?

Example:
If I buy 93, how much of the last guys 87 am I buying at the 93 price?
I'm running a tune and I want 93, not almost 93.

I can't find a station around here that has discrete hoses for each octane rating anymore.

I think I read about this once a long time ago and you can expect to get 1/10 of a gallon of the octane the previous customer pumped. My wife and I will use a pump a higher end car or motorcycle pulls away from if given the chance, not that it matters. We also try to use gas stations in better areas. A gas station in a bad or low income part of town removed from interstate travelers is probably selling higher octane gas that has been in the storage tank for many moons.

I heard some time back that it's generally a 1/3 to ˝ gallon in the hose. It will depend on thehose as well. Some new pumps have a smaller diameter hose from the outside so I am assuming it's smaller inside as well.

The only way to guarantee 93 is to follow someone pumping 93.

Cannot see signatures any longer so it doesn’t matter.

I've stopped twice now at a new KwikTrip in Fon du lac, WI. E091 on a seperate dedicated pump and hose right next to all the others so someones thought this through.

Is this really something to worry about? The difference will be completely negligible.

Your 93 tune should not be so close to the ragged edge to where this affects you even slightly.

I was told that there could be 2-3 gallons in the mixer. There's more than just the hose

The more you buy at once, the better the odds you get what you want.

I've always heard between .25-.50 gallons in the hoses and valve assembly.

I've been thinking about bringing a gas can in my truck. I can dump the first gallon in my truck, then the next 5 in the gas can.

Calculating the volume of a hose = A good math exercise

The volume of the mixer etc. = intel

Fretting the delta in octane = BITOGers OCD = CHARMING

Waiting for a high end car or motorcycle to leave a pump = Something a stalker would be better at doing

"I can dump the first gallon in my truck, then the next 5 in the gas can." = Additional risk by complicating the handling of a dangerous fluid

I say, "Have a good time". The nasty people around me would say, "Get a life". I don't say that to people.

The octane per each grade is a MINIMUM, rest assured that if you are paying for 93 min octane, that's what you'll get at a MINIMUM.

So what is the ID of most hoses, 1/2"-5/8" maybe? And 10' of hose?

If you are only buying a gallon or 2 for my mower or dirtbike and I am paying for the Premium Non-Oxygenated stuff I don't want to get a gallon of ethanol laced fuel. For me it isn't the octane that I am worried about, but I don't want the ethanol in it.

When I was very young, I'd wait till the local gas station was closed and take a gallon can and empty all gas hoses to get gas for my car. I never got a full gallon from the 6 separate pumps. Ed
