If this subject has been addressed before, I am sorry for the post. Please forgive.

I have tried to locate in my manual if ethanol 10% additive is OK. Seems that the big switch is on and I haven't a clue?

2006 Dak 4.7 Mag QC - completely stock with 1900 miles on it.

I got chewed out by another dealer last fall (different make) about using ethanol in fuel. Seems it was causing the check engine light to come on and a quick check of the code says it was the cat. convert. causing the caution. I told him to shove it since no ethanol had been put in it....period... Rude, Crude service manager. He said that cut-rate gas stations were slipping in ethanol to sell it cheaper. Hell I was driving cars before they had cc's - got better mileage, and power and could run anything in it. In a pinch, dumped a gal of bootleg in the tank and it ran like a raped ape. But that was $20 worth of good stuff and I was always rebuilding the engine for 'hauling purposes' anyway... [gas back then was 9ยข to 12ยข a gal] hard to believe...

Makin' good brew is still an art.

Thanks for listening and any feedback is much appreciated.

 

Sometimes if i want to put in 89 when its really cold out, the only choice i have is 89 with 10% Ethanol added. Ive ran it before no problems. Id say its O.K. as long as its not E85 !!!!

 

All fuel here in Michigan has had 10% Ethanol for as long as I've cared to notice about 5yrs now (I may be wrong on time length) but it is standard issue here in the midwest, so it will be just fine!

 

Agree with the others. A 10% blend of gasoline/ethanol is all I run in my 2006 Dak 4.7L. The 4.7L cannot run on E85 fuel, like some of the Chevy and Ford trucks, but is fine with a 10% blend.

 

Thanks everyone for your infomation.

I happened to run across a website that had this info extracted from the manual from Dodge:

DaimlerChrysler

Approval applies to Chrysler, Dodge, Jeep, Plymouth and Dodge pickups.

"Some fuel suppliers blend unleaded gasoline with oxygenates such as 10% ethanolโ€ฆ Fuels blended with these oxygenates may be used in your vehicle. Reformulated gasolines contain oxygenates, and are specifically blended to reduce vehicle emissions and improve air quality. DaimlerChrysler Corporation supports the use of reformulated gasolines. Properly blended reformulated gasolines will provide excellent performance and durability for the engine and fuel system components."

Good info on E-10 Unleaded. Some reports indicate a lower gas mileage even though the ethanol has a higher octane rating. I guess I can then expect to drop 1-2 mpg especially when towing and pay more for it.

 

Funny you should ask abouth this fuel. The switch over to summer time fuel(10% ethanol) is quoted as part of the reason gas has risen on average $.60 in the last 2 months. That along with a lack of refining capacity. Here in the Puget Sound region they also run the ethanol mixture during fall/winter to cut pollution. Why don't they just make that the standard mix nation wide and build more refineries? $3 gallon means no vacation this year.

TASTE THE HEAT AND ENJOY THE PAIN

 

You know, I've always wondered that too. But, I think that these gas hikes are just a bunch of BS. Watch and see what happens at the end of the quarter and see how many billions the oil companies made in profits.

 

FYI.. An E85 4.7l will be available on 2007 dakotas..

 

From what I understand all vehicles were made to be able to run 10% Ethanol at least by the 80s. My family have used E10 in all of our cars for years and have had positive results. The dealer is B.S.ing you. I have found E10 to get the same if not better than 100% gasoline.

The reason why the prices go up is a rise in consumption during the summer by people going on vacations. The price of a barrel of oil from OPEC keeps going up. China is consuming more fuel all the time. The Gas companies are internation and sell over there as well. That is why they are making money.

There are more Ethanol factories being built. The problem is I don't think we have the crop capacity to produce national 10% Ethanol no matter how much I would like to see it happen.
