What's in your tank?

Not hijacking OP. Just curious about your thoughts on pumping the 93 at the local station. There's about a 80-90% chance the previous auto to pump fuel put in the low grade 87. The blender/switch (for lack of not knowing the correct term) is usually located down around ground level at a normal filling station. How much of that 87 fuel is pumped into your tank before you get full 93? My guess with the piping from the "switch" and through the hose is probably close to 2 to 2.5 gallons. If one was to fill their tank at 1/2, we'd really only be getting 87 octane, correct? How do you combat that?
This is why I seek out stations with three hoses (one for each grade) vs the single hose stations.
The most common station (although not all) with the 3 hose around here are BP, Exxon, and Sunoco

WARNING!!!
E15 (ethanol 15) has now been approved in many US states.

I'm really not familiar with the dispensing equipment so I'm not sure how much further it is to where the switch occurs, but if you calculate a 10 ft hose that's 5/8" inside diameter that comes out to 36.82 cubic inches, which is about .16 gallons...
As to how to combat the issue? Get in line behind someone with a turbocharged sports car that requires premium.

I just did a little searching, looks like most fill hoses are 3/4"id, and i'm sure the piping we don't see is probably close to 8-10' plus the 10' hose. If I'm doing this right (admittedly I was too lazy the first time) that should come out to roughly .4 gallons. Right? pi(Rsquared)(height)=volume.
Guess it's not the end of the world.

I've actually been "that guy" to give away a few gallons when filling up before.

I run E10 87 octane for the last 3 hundred thousand miles + in all of my bikes which have all versions of H-D offerings from an 883R to a 120R.
They have been through most of the mountain ranges in the US and Canada,through deserts and Death Valley, caught in accident tie ups on the Interstates and never an issue at all.
They get great mpg. But I help them along with oil coolers if not standard equipped, SE wires and iridium plugs, periodic carbon removal, stock exhaust but high flow intakes and a proper AFR. All that makes for a cooler running engine and an uptick in power.
I am not caught up in the nonsense of what type pump or hose there is. I just fill that sucker up and ride baby ride. I did 42,380 in 2015 and saved around $600 over the 93 octane cost in this area.
I have run too many engines for too many miles to even listen to the high octane total BS. EPA/DOT mandates that any vehicle sold to operate on US roads MUST be able to run on 87 octane.

It's about hprotecting the engine from the fuel you put in your tank.
Let's face it folks. We're bein screwed. So what are you doin to protect your bike from those who feed us the cool aid?

Bottom line is Ethanol is a mildly acidic molecule which accelerates the corrosion process in iron-based alloys or aluminum, brass, bronze, silver, lead and other alloys and rubber seals found in most fuel systems.So how are you protecting it?
Stop drinkin the cool aid folks.
However, the American Petroleum Institute (API) strongly disagreed citing further testing provided strong evidence the “use of E15 could harm car and truck engines, potentially affecting millions of cars and trucks.” The president of API went on to say, “EPA’s decisions in 2010 and 2011 approving E15 ethanol-gasoline blends for most American vehicles were premature and irresponsible. EPA approved E15 knowing ongoing vehicle testing had not been completed. Worse, as API noted in its press briefing two weeks ago, it approved the fuel even though government labs had raised red flags about the compatibility of E15 with much of the dispensing and storage infrastructure at our nation’s gas stations.” (bgfor.me/api)
Even several OEMs—including Ford, Toyota, Nissan, BMW, Mercedes-Benz, Honda, Chrysler, Volkswagen—are against the approval of E15 and stated they will not honor warranties on older cars (before 2001) running on E15. They are “concerned about the effects of E15 on engines, fuel pumps and other fuel-system components in cars that were not designed for it.”
EPA approval and OEM threats aside, it is ultimately up to consumers whether they fill their tanks with E15 or stick with the more standard E10 (or even go out of their way to buy “pure gas”). Either way, they’re going to need something to keep their fuel system clean and protected; and BG’s got just the solution!
