Title: the new gas...
Post by: Nate on May 01, 2006, 09:13:28 PM
anybody else hear have that mix  in their car for a full tank yet?  myself and a few friends all had it run through resently and it burned alot faster than usual,.. meaning instead of getting 230 miles to a tank, getting 150.  i wouldnt care as much if the cost was 1.50 a gal, but its over 3...:yuck:

You talking about E85?

it's either that, or the 10% Ethanol stuff-E10 is what I call it...
Maybe that's why I get a bit worse mileage than I should...

Oh wait, it's my heavy right foot, lmao

Seriously, most vehicles won't get the mileage they do with straight unleaded...Just remember one thing though, alcohol favors higher compression engines, and has (a bit) more oxygen content than gasoline.

Tbird doesn't like it. I've lost about 2-3 mpg.....and I have an AOD and 3.73 gears so that doesn't help:mad:  I might try 89 octane to see if that helps, I doubt it though.

E-85 requires a fuel system upgrade. So what is this "New" gas?

We have E15 pretty much everywhere you go in Chester county now.  It happened in like a week.  Wawa is the only place I've seen that has posted the change....asking..."Can your boat run on an Ethanol blend?".....who cares about the boat...what about our cars!?!?  My Cavalier is doing ok with it.  But today an 87 Town Car came in with a shutter under accel problem.  I suggested a transmission problem, but a co-worker pointed out it had a misfire.  It didn't dawn on me until now that it might be the gas screwing with the engine.  We performed a couple various things, like a tune-up and corrected the firing-order issue the customer had created, but still ran horrible.

Hmmmm.....I'll have to run this idea by the bosses.

I wouldn't think that e-10, or even e-15 would make it run rough, stutter, but hey, I don't know everything, lol.
 
Come to think of it, we use a mix of gas/alky in all our farm stuff, except the diesels...it varys from 10 to sometimes 35-40% alcohol....

The new gas is not really "new" at all, they're just not putting that MTBE stuff in it anymore, ethanol gas has been around for well over 10 years.
Some vehicles have been documented to use e85 w/o any bad effects, some won't tolerate any more than 15% ethanol....
Last summer I dumped about 5 gallons of pure ethanol in my gas tank on my truck, only result was I made it about a mile, and the truck died, had to pump the tank out, and replace the fuel filter, cause of the water the stuff has absorbed. Didn't help any that it had sat in a metal (think not vapor tight), and had gotten "wet"
Other than that, the truck runs great, or as great as a 230,000 mile 5.0 with a coula bolt-ons will run...;)

i was talking about that 10% ... im going to see how the hyundia likes it, it was at 350miles per tank with regular, in an other week or so (maybe) i'll see how many mpg that dropped. this is kinda like when they stopped putting led in gas... this sucks guess i'll have to buy gas at the track or something for my car.

Hm..i get my gas a BJs and it says on the pump " Contains Ethenol" i'm not sure how much, but i have noticed that it doesn't last as long.

What's funny is my 93 Buick Century with a 3.3 V6 runs fine on 87 with the 10% ethenol but the Tbird hates the same gas, and I get the Tbird the better stuff from Mobil or BP. Maybe the Tbird would like 89 or 93 better, but I doubt it.

The cougar has been missing lately. I don't think it's the gas though.
The Tib seems to have improved a bit which is weird since I heard there was going to be a 3% drop in fuel mileage. Normally I get about 29-30 mpg. This last fill up I got 35:dunno:

T-bird isn't missing it's bucking under hard throttle. I just gave it a full tune up before I took it out and it ran fine with the tank of gas from last fall in it (yeah I put Stabil in the gas). I filled it up with the new stuff and it hates it for some reason :dunno:

did u people ever try and run your car on half 89 and half air plane fuel :-D ....i have !!! .... burns quick and idles mad low so i always gotta have my foot on the gas ...but my car went faster!!!!!!!!!

Post by: Sick88Tbird on May 11, 2006, 10:27:31 AM
Yeah, I'm sure it didn't go any faster.  Higher octane fuel is unneccesary unless you have a need for it, higher compression, advanced timing, etc....even then you won't need more than 93 octane.  I ran 100 octane race fuel at Atco one day because I didn't have enough gas to make it through the rest of the day and still get home...I was nearly on "E" and spent $30 on this  gas(about 6 gallons) and noticed ZERO improvement in quarter mile times and the car drove like  at part throttle and idle until I ran a few tanks for 87 through it.

As far as the new ethanol additives in the gas...I haven't really noticed any drop in fuel mileage with it...maybe because the car is runnning so rich and I only get like 16mpg anyway.:toilet:
