Flex Fuel question

    Some say, the Captiva's 3.0 SIDI V6 is capable of flex fuel.

    However, I'm not able to tell whether or not it will run on e85 or not. My vehicle did not come with an owners manual, and I'm not able to locate a definite answer online.

    Well if it is would you like to get about 30-40% LESS MPG's?? Do you have the E-85 flex fuel badge in the back?

    Check the RPO sticker in your glove box. If it has LFW, then you have the flex-fuel version of the 3.0. If it's LF1, you don't.

    Less mpg does not show the whole picture. Let's take last summer...

    I could get E85 for $2.86 a gallon, E10 was $3.86 a gallon, and Regular was $3.95 a gallon. On E10, my mpg was around 18 average in my Silverado. That was a cost per mile cost of almost 21.5 cents a mile. With E85, I was getting 14 mpg. That cost per mile was just under 20.5 cents a mile. So, even though the fuel mileage was less with E85, my cost per mile was lower.

    Those that look only at mpg run the risk of spending more than they need to for fuel. One has to know the cost per mile to find out what is the best value. In my case, the cost differential is not as great, so I am using E10 thru the winter. When the prices fluctuate next spring, I will reevaluate things and, more than likely, will go back to E85. These fuel price differentials are a seasonal thing.

    Thats cause you are in the Farm belt E-85 here in the NE is about only 20-30 cents less then Reg and a few stations have stopped selling it..

    Ive been watching E85 prices locally for over a year, when you can find E85 the price never strays more than .20 less than regular.
    It needs to be much closer to $1 considering loss of mileage and the fact I have to go out of my way to find it for useage to save me any money.

    And that $.80 to $1 spread does occur during the summer months usually. Sure, I live in the corn belt where this is a viable solution. Nothing like being at the source of where this stuff is made. But that really wasn't the issue. Some will use it because they think it is "greener" to do so. Some won't use it because they have some sort of paranoia gland and fall for conspiracy issues. E85 is just a fuel. I was just commenting that one needs to look at the cost per mile to use a fuel as opposed to only looking at MPG. Many people can't see beyond the MPG numbers and look behind the curtain and see what that mpg is costing them. If it is costing a couple of cents a mile more to use a fuel that gives the appearance of being great because you are getting a couple more mpg out of it, then what's the point?

    I am not impressed with mpg figures that people show. It is the lowest cost per mile that impresses me more. I didn't say the lowest cost at the pump. They are different things. I am only advocating that one use the fuel that gives them the lowest cost per mile to use. If that is regular, then go for it. If it is E85 then go for it.

    Yes I agree there are those on both sides of the fence of this issue.
    If use of E85 saved me money Id have no problem using it, I already have 1 vehicle converted to CNG and another I use Bio Diesel in.
    From experience in different parts of the country use is predicated mostly on price and availability.
    My uncle owns a small chain of service stations in Nevada and Wisconsin, in certain counties in Nevada he' s required to offer E85, his E85 sales are terrible, the cost involved vs sales is a negative profit margin on that particular item. I Wisconsin he maintains a positive profit margin with E85 and carries it at all service stations because it is a profitable product to carry.

    You should convert to electric, and run a small diesel generator in the bed. :)
