I use 93, E85, or Pure Meth.

I think the OP does not understand Octane.

 

Everyone that runs E85 are your trucks flex fuel?

 

You get the most performance and efficiency from the lowest octane you can run with out knocking/automatically retarding the timing.

Extra octane does not mean more power, more efficiency, or a cleaner motor. It means more cash out of your wallet and into the hands of the fuel companies.

 

Yep pretty much...

 

You know you should have bigger injectors to prevent 100% loading right?
(only run E85 in my car sometimes)

 

I just get whatever is cheapest.

Question, can a non-flex fuel truck run E10?

 

regular gas is E10.

 

oh well see i dont remember seeing any of it around here but when i went to iowa they had signs everywhere warning you that it was e10

 

I just asked that cause one said he runs e85 cause it is normally cheaper

I know you cant run e85 in a non flex fuel vehicle it will cause problems down the road

 

Here in bham we have BMP and they sell all the race fuels. I ran like 98 or 100 at the track and didn't really notice a difference. My tune just wasn't taking advantage of the higher octane. Smelled awesome though haha.

 

There is a Sunoco not far from my house that has 100 and 110 at a pump. That's what I run in my truck.... not really. I run 87 most of the time, but if i feel the need to treat myself I will fill it up with 93, and tune it of course.

 

whatever is the cheapest i can find. usually murphy's. At murphy's they have a sign that says warning our fuel contains E85. should i be worried about that?

 

All gas stations here that serve e85 the hose and nozzle are all yellow

And anywhere I have been outside of Springfield are the same way of course diesel is green

 

Some of you don't understand what "E85" means. E85 means "85% ethanol". Most places have 10% ethanol in normal gasoline, no matter which octane you buy. One of the reasons I don't use E85 all year long is because E85 is not always E85, sometimes it is E90, sometimes it is E70. If I ran E70 without knowing it (thinking it was E85) without turning down my boost I could blow a hole in a piston or worse.

Ethanol is better than gasoline for a few reasons. 1 it burns cooler, 2 it is more highly oxygenated. This is also why you get worse mileage and need bigger injectors than for normal gasoline. This is why I have 1600CC (152 lb), 1200CC(114lb) & 1000CC(95lb) injectors for my car. (depending on which fuel I use)

Flex Rangers come with bigger injectors, not ones this big though.

 

Your tune is not the problem. It is your effective compression ratio. Smells good because higher octanes require more for ignition. You were smelling unburnt fuel. I don't know if you still have converters on your car, but if you do, the converters were working overtime to burn off that excess fuel.

 

Those ethanol stickers are just trying to get more people to buy it because Iowa produces so much ethanol.

 

the highest we can get here is 91 (other then 100 octane race gas, which i ran in my grand prix at the track)

i run 91 in the ranger, thats what its tuned for. but honestly, on the 87 tune and 91 tune, i dont think i can feel much of a difference. if 91 gets above 3 bucks, then im going back to the 87 tune

 

When you squeeze hot air mixed with fuel it wants to ignite. If you use a fuel that is more resistant to ignition than you can squeeze it more. If you aren't squeezing it more you won't feel a difference. Upgraded fuel on a N/A or stock compression engine is a waste of money.

 

I cant run e85 in my truck cause my injectors, fuel pump, fuel lines gas tank are not set up to handle it.

Thats why I laugh if I see someone putting e85 in a car not set up for it. Ya it cost alot less but in the long run when you eat through your fuel system it wont be cheaper

 

It costs less $ per tank, but you go through a tank quicker.

I get 22-24mpg per tank on 93.

I get 14-17mpg per tank on E85.

 

Not true. Regular gas can be up E10, you can get gas with anywhere between 0% and 10% ethanol in it. So it's not really E10 100% of the time, only sometimes it is.

 

They only make gasoline here in Missouri e10 during the summer I think during winter it is regular old gas

May have it backwards but I know part of the year it is and the other part it is not

 

Sometimes when I had my old Ranger , and I was still towing , I would run the gas out of junk cars we were scrapping out. So I was probably running some ungodly mix of water , 87 , 89 , 93 and rust. And what craps out after a year of doing that ? My transmission

 

Because the stations that sell 89 for the cheaper price don't offer an 87.

Typically its 87 91 and 93. Or the other stations sell 89 91 and 94

I really couldn't tell you why they run these grades. It must be the supplier.

 

87 89 93 here..
