If you are calling a 42-year old man a kid..............I appreciate it. Seriously, though, it's a pain in the ass because there is one pump in a 120-mile radius from me. I live right near it, but I live in Texas, so long-distance driving is common. If there isn't another pump on the drive out to the boondocks, I have to be able to make it there and back without a fill-up. I keep my laptop with me in case I need to switch back to gas, but it's still a pain in the ass for a DD. Luckily, mine is not a DD.

 

worst thing about being E47 tuned is pulling up the gas pump(91) then pushing my car forward to the E pump lol people look at me like im crazy and sometimes people even come to help me push

 

You can just start it and drive it to the next pump. You don't have to push it.

 

 

haha i always push it, because RACECAR!

 

hahahahahahahahahahahaha!!!!!! that's too freaking funny dude!! i can picture it. lololol.

i approve of your methods

 

lol.. sad to say, but I do the exact same stupid **** if I'm stuck blending right at the pump. I'm just super **** so I don't like to even just start the car with my blend not being dead on.

 

Talking to someone about going E47.
BUMP

Anyone with experience?

 

The guy above your last post can get you where you want to go. E-47 is great, isn't really a hassle, and can add about 25 hp due to being able to run more timing. Lots better mileage than e85.

 

So you put in 55.2% e85 and 44.8% 93? Cause the way i see it if you guys are doing half and half you should call it e42.5

 

That's how I roll! At least at the stations I go to the pumps are next to each other. There are stations on the other side of the town where you can pump 91 AND e85 out of the same pump from a different nozzle.

 

Most gas is E-10, so you get 5% from half a tank of gas, and then 42.5% (on a good day) from E85. So it's more like E47.5

But there are stations in the US where gasoline is not oxygenated with ethanol, and has 0% E.

 

I've got him covered. I think the concept of running fuels other than gasoline is still a very new idea to him. He wants to weigh out whether it is something that he would feel comfortable with having to run on a regular basis.

Here in Arizona there aren't a ton of stations with E85, so while it is still perfectly feasible to run Ethanol fuels, you just limit out 90% of the gas stations. To me, that's the only real downside since the fuel mileage on E47 isn't actually that bad (maybe 10% worse than straight gasoline) but the power and reliability of it is outstanding. It's not like you ONLY make more power, you tend to make that power under even safer conditions than a less powerful 91 octane tune.

 

In Missouri almost all of our stations have E85 side by side. Different nozzle of course. Makes filling super easy. Maybe an extra minute for the second transaction.

 

Is it still considered E47 if the gas mixture is 91 octane? I'm looking at doing this to my cobalt this summer. I wanted to run E85 but didnt care for buying the zzp fuel lobe with opels. I have done some research. Is anyone actually monitoring the ethanol percentage during/or after fueling up? I've hear that some E85 stations may have less or more then 85%. Wouldn't this directly affect a E85/E47 tune?

 

Yes I always check the e content when fueling. You can use 91 verses 93, it just lowers the octane slightly.

 

What are you using/what do you use to monitor the e content? Gauge, testing kit?

 

I purchased a little test tube setup made by quick fuel. Pretty standard setup that a lot of guys use. Think I got it on amazon.
The e stations in my town replaced their 93 pumps with e pumps so I actually have to mix them in gas cans.
