Gas thread

Yes ethynol is cheaper... and in the winter they inject butane in the gas as well!!!!

Anymore Dlit... ethynol is always added to everything... I'm just saying that its a cleaner, it really is just de-natured achohol.

Here's another sniplet from another gas thread on WOS

The only difference between any "branded" gas is like saying Pizza Hut's Deep Dish is better than Jet's Deep Dish Pizza. They both cost similar, both fill you up and clog your arteries. What is the difference? Slight taste but virtually the same.

Generic vs branded is that the branded gases use more additives (cleaners, milage enhancers, epa crapola, ect).

Do you remember when shell rolled out its "V-Power" and the commercials showed 2 of the same cars driving. One on "the other brand" and one on "V-Power". The "V-"power" car went farther on the same amount and got better gas milage. I was working in Flint at the time and in genessee county they got their Shell gas from the Mobil tank farm (using their own "Shell additive") on Dort Hwy. When they did the switch the Mobil operator just changed the amount of additive from "1 part" to "3 parts" per X number of gals. Increasing the additive, therefor the milage enhancers and detergants, giving you better gas milage.

This idea is the same when it comes to generic vs branded. The root product of the gas is the same. Its the additive that changes in quanity (generic vs branded) and "flavor" (branded vs branded vs generic vs generic).

That is why I bring up the point of gas station quality. Not only does it bring to light the quality and cleanlinest of the underground tank but also the calibration of their pumps. Sure the pumps are calibrated and checked by the state.. but you know...

And lets not even talk about octane... that is simple... if your motor isn't setup for it, ie; high compression, advanced timing, ect... then you're wasting your money. Send it to me for your gasoline education.

Does the butane in the gas have any effect on MPG?

I've noticed in my 40mpg beater that we average a bit less now, doing the same driving, then in the summer..

I'm not sure... I don't think so...

Probably cause it's cold out.

1. you may let it idle more, to warm up.
2. cold air is more dense, thus, more air is run into your engine. more air means more fuel.

We don't let it idle more..

But yeah, I agree with the second one.. Makes sense..

So isn't the main problem that Ethynol provides less energy when it combusts, and also burns at a different speed than typical gasoline?

Thus that is why bikes (which require more precise air/fuel mixing and higher octane due to high rpms) don't work well with anything more than 10% ethynol?

Wouldn't running a higher-percentage ethynol blend be similar to running too low of an octane, i.e. you would get detonation and pinging?

The warm up and idling stuff is a good point.

Also, you're generally travelling slower and thus getting worse mileage.

But the cold air part... I don't think so... the same amount of fuel is injected each time the injector squirts... but since the air is denser, the compression ratio actually goes up and the engine is MORE efficient and makes MORE power with the same amount of gas.

Also, the cooling system (radiator fans and such) need to do less work to keep the engine at optimum temperature... which would increase the mpg theoretically...

I'd say that your car is just starting to run shittier than it used to, and you will still see the less MPG even when summer hits.

No the ehtynol isn't effecting you. You won't find it higher than 10% in today's market. Its not truely effecting anything. Its definately not a octane thing... the ethynol itself is 103 octane so that's not it. The more you got in the higher your octane would be. Its after the ethynol is added that they add in 86 or 87 octane gas to knock the octane level back down to 93. Otherwise it would be a great deal higher when they added the ehtynol to the 93 octane gas.

Possibly, The muffler is basically rotted out now, car is waaay too loud now, could have somethin to do with it too..

We put 18k miles on it since September.. Cars got 140k now..

I put Shell in my Jeep. My wife prefers Hess. I get real shitty milage from Sunoco gas...so I don't buy it.
