Siphoning out my gas tank

Just saying it's not as big of a change or different product that most think it is. It's done more or less to help with the distillation point. Which in diesel NO: 2 can be waived during the winter months which are October through February if the cloud point of less than +10 degree F has a minimum viscosity of 1.7 cSt.

So all I'm saying is the fuel really is no different. Just some bs that needs to be done to keep folks happy.

Thats all I'm getting at.

Oh, I know it's some EPA BS alright.

There is a big difference in winter gas and summer gas in ny. My supra runs completey different with winter fuel(had to move storage areas and had to fuel up). EGTs where higher, timing was all over the place. Gas milage goes down in my truck gas truck yet up in my diesel. I know for a fact there is different gas coming out of the pump in the colder months. The gas stations even admit it. Delta sonic water mixed with gas is the worst out of the bunch. Sunoco is where I will always get my fuel because the cars change the way the run the littlest with their fuel.

Then tell me why there's such a disparity in gas mileage between what we call "winter" and "summer" fuels. Is it an additive? Ethanol? There is a distinct difference.

Sure thats any easy one. Its the evaporation class point due to the difference in temps. This may not mean nothing to you but its due mostly because of whats Free of Particulates. Depending on the season, the class range of that changes and affects the evaporation degree at which its calculated based on the F degree. And yes this is different in many states. All fuels have different specs based on your region and whats allowed by the state.

It sure is. Right now I have the EPA and DOE bothering me for my annual reports on what was sold for the year and to who and for what reason. A bunch of useless departments that the taxpayers shouldn't have to pay for if you ask me.

To answer the OP question lol, it most likely are the additives you put in. Those mixing with whatever additives the gas station may have put in could real be a bad combo and not compactable with one another.

I was under the impression that gas powered engines got worse mileage in the winter because of the cold temps, but I could be way off base here.

Just found this on www.ask.cars.com
The difference between conventional summer- and winter-blend gasoline has to do with the Reid Vapor Pressure of the fuel. RVP relates to the volatility of a gasoline. The more volatile a gasoline, the more likely it will evaporate as the temperatures rises; evaporated gasoline contributes to unhealthy ozone and smog levels. Summer gasoline has a low RVP and is less likely to evaporate when compared to the high RVP winter grade. The Environmental Protection Agency says conventional summer-blend gasoline contains 1.7 percent more energy than winter-blend gas, which contributes to the summer blend’s slightly better gas mileage.

The Energy Information Administration says the switch between the two fuels happens twice a year, once in the fall (winter blend) and again in the spring (summer blend). Summer-blend gasoline is typically more expensive to produce than the winter blend, and it won’t affect vehicle performance or the durability of the engine and fuel system, according to the EPA.

In many large cities as well as California and New England, the EPA requires the use of reformulated summer- and winter-blend gasolines. These RFGs contain oxygenates that lower RVP and other toxic chemicals even further than conventional gasoline.

I like the idea of disconnecting the line somewhere and turning on the fuel pump.

Twice every year in the United States, the fuel supply changes. It's known as the seasonal gasoline transition. This change is the biggest reason for the price hike in summer gasoline. Depending on the time of year, gas stations switch between providing summer-grade fuel and winter-grade fuel. The switch started in 1995 as part of the Reformulated Gasoline Program (RFG), which was established through the 1990 Clean Air Act Amendments. The Environmental Protection Agency (EPA) started the RFG program in order to reduce pollution and smog during the summer ozone season, which occurs from June 1 to Sept. 15 [Source: EPA].

I know my shop siphoned gas out of another member's tank when they tuned it for a supercharger. He had gotten a bad tank of gas and they couldn't get the timing right. They siphoned the gas and then refilled it with 93.

I'm sure your shop can siphon out the gas.

this or drain it at the line..


as for all the bull about gas start anouther thread that i NOT this guys problem.as he added his problem his self. sorry man.

Thats why I don't use stabil. I mix half a tank of 110 Unleaded race gas with fresh gas and put it on the battery tender. I start it once a month and a little drive if its dry.

I'd still put Stabil in that mix. Stabil is to keep the gas fresh and not forming the varnish gunk as it ages. 110, 93, or 87 will all age into varnishy gunk.

Stabil isn't going to kill the power. Spark knock from old gas is the most likely culprit. I've run Stabil in toys with zero knock. Months later, tons of detonation on the same tank - due to the gas has lost octane over time. The Stabil kept it from gunking up, but old gas is old gas, not going to have the same octane as fresh stuff.

How would adding 1.5% mixture of anything result in a 8.5% drop in hp.

The fuel would be last place I would be looking at right now
