Has anyone heard of this?

[OR VietVet]

I saw this at my Glock forum:


"A bit of worthless trivia. I read this on the internet so it has to be true.

A typical service station sells 87, 89, and 91 octane gasoline. They just have two underground tanks, 87, and 91. The 89 octane gas comes from both tanks and is mixed at the pump.

True or false? Anyone know?"

Is it the norm or a random few or certain companies that do this?

I wonder if the stations with unleaded 88 and E85 do too.

Yes, the fuels are mixed at the pump. I dont remember the ratio, but its like 60/40 at some locations. Other locations is 50/50. If you have a 5 octane difference from regular to premium, its 60/40ish. If its 4 Octane, its a 50/50.

E85 is mixed at the plant, and then delivered.

I mean like 87+ a percentage of E85 to equal the 88/E15.

Little known fact, if you live in a location with a 5 octane difference, your actually being ripped off by .5 octane point. If you know how many gallons your going to put in, put half of regular in, and half of premium in, same cost, but a slightly better gasoline.

Blender Pumps

Another trivia item. As a motorcyclist, I never liked blender pumps. Figured the first bit was the last guy’s 87, for which I’m paying premium price. And I’ll leave a hose full of premium for the next guy. Things you think about when you’re only buying small amounts.

Some blenders are easily identifiable because there’s 3 grades but only one hose.

95% of the time I trigger the pump off lever and give the handle a squeeze to get the last little bit of fuel out. Been doing this since the gas crunch of the Jimmy Carter era. I pretty sure I'm beaten "the man" out of a gallon or 2 by now.

The Mobil station I get my E85 at has a seperate hose/handle for it from the other hose/handle that's used for 87/89/93

E85 is made with 85 octane gasoline at a refinery but when they blend it to make E15 or E30 and such, they use 87 from the tanks at the gas station. The problem I have found over the years, the pumps are not on or working and I get a tank full of 87 when I was supposed to get E30 or E15.

I doubt it’s always the case. In the 2000s in Iowa, places commonly sold 87e0, 89e10, and 91e0 and 89e10 was the least expensive. So I’d be surprised if they weren’t dealing with 3 tanks

My e85 station also has e15 and then 85/87/91. Last time I filled up they were out of 85/87/91 (single hose) but they had e15 and e85 which each have their own hose.

Did you check your alcohol content afterwards? I reckon there are multiple ways to store and dispense these fuels.

Poured it in and drove away. I’ll take the over a dollar a gallon cheaper e85

 

[OR VietVet]

Here in Eugene today I drove by my Chevron I use and Regular 85 was $3.70 a gallon.

It is comical how we got here, isn't it.

 

[TollKeeper]

Filled up with E-0 Premium at 3.71 a gallon. This truck really likes ethanol free. 1.5-2 mpg better. And its the same price as mid-grade E-15.

Would not mind trying to see if I could do a E-85 conversion on the Esky affordably. Its $1.20 cheaper a gallon.

Saw my first $4+ a gallon price yesterday for 93 octane. I look forward to seeing just where these prices go before the end of 4 years.....

From everything I have read online flex fuel isn't worth it from a cost perspective unless you have a performance setup that actually can use the extra octane and cooling effects of ethanol. Most all street driven ls engines don't. Your mileage will drop enough that the cheaper fuel becomes more expensive and there is no performance gain for our low compression engines.
