Is this the latest in EPA shenanigans? First I've heard of it.

 

You're at the wrong pump

 

That's been going on in many states for many years.

 

I have no idea how oxygenated gas will work in a 4 stroke car/truck engine, but I can tell you it's awesome in 2 stroke motors.
Considered cheater gas in most 2 stroke racing circles.

 

it has two handles haha

But I wasn't even in my truck. I was in my work vehicle. Still diesel though.

 

"Oxygenated" means it has ethanol in it. Here in MN (and many other states) all gas has 10% ethanol unless the pump says it's "non-oxygenated". Only a few stations in my area even carry non-oxygenated gas. Plus, it's usually only available in 91 octane and costs about a dollar more per gallon than regular unleaded. Not to mention it's technically for off road use only, except for collector vehicles. (more than 25 years old)

 

"Winter blend" gasoline in California since '92:

Moved to the General Automotive Discussion forum.

 

Ethanol is still better than that nasty MTBE crap we were subjected to in years gone by.
Anything that reduces the potential energy of my fuel by ~10% on a per volume basis is just another way for the petro companies to reach into my wallet, IMO.

 

It simply leans out the mixture. Most factory carbs were jetted for smoothness and power over economy and emissions, where emissions were only measured at idle. The original intent was to "clean up" older vehicles, but since EFI has been standard since the mid 1980's, that is no longer the point. Now, its really an ethanol mandate. Today, he winter/summer blend has to do with vapor pressure, not oxygen content itself, as it is required all year. The wording on that sign on that pump is very old. Note from the linked report, that the requirement started in 1991, when there was still a large fleet of non-EFI vehicles still out there. MTBE, not ethanol, was often the oxygenate, a ground water pollutant.

 

the same junk with a new name . and neither of my old vehicles like it , the 53 effie and the 52 customline , both flathead powered and designed to run off corn alky when new , and my 95 bird 4.6 with a chip really dislikes it . i can no longer find uncut fuel of any octane here and the putor in the bird has cut it way back and lost a considerable amount of power and torque due to this crap , no matter what name they give it .
