Sup peeps... Lately i have noticed that the fuel efficiency in my main ride has not been very good. I use to average 280-310 miles per tank but now 200-210 miles per tank. This bad efficiency started in the winter for me so i thought it was due to snowy weather conditions but recently heard that BIG OIL has been adding more ethanol to our fuel. Now iv read that ethanol laced fuel can cause gas leak/spilling from the carb in older cars and that seems to happen with my buick now and then which made me wonder if anyone else is having that issue too. Here is the article i read about the gas leak. Scroll down to FUEL LEAK BY THROTTLE SHAFT http://www.thecarburetorshop.com/Troubleshooting.htm
The "Winter" gas here in Jersey does the same to my everyday work ride. Not sure what they are adding to it now but 10 miles/gallon really :moonu:
Cold weather seriously affects fuel economy. The following figures are for a Civic Hybrid, but you'll get the idea.....almost 30% worse at 5* as opposed to at 95*, about 20% worse at 25* as opposed to 75*. MPH-----AMBIENT-TEMP-----MPG (US) 60------------95----------52.98 60------------85----------52.62 60------------75----------51.16 60------------65----------49.12 60------------55----------47.22 60------------45----------44.67 60------------35----------43.05 60------------25----------41.54 60------------15----------39.41 60------------05----------38.09
Remember that every state has its own formula of gas, and most have summer/winter formulas. So "your mileage may vary". My MPG typically drops 5% in the winter, and I think this is about average. I can pretty much peg it to September 15, when Massachusetts changes to "winter" formula. If your MPG dropped 35%, there's probably something else going on. There has been a movement toward 15% ethanol, but as far as I know most states still stick to 10%. -Bob C.

The best fuel economy that I have ever personally gotten in any car was in my '05 Dodge Magnum RT (Yup, it's got a Hemi). It was in Virginia on a 90+ degree day. 173 miles on cruise control set at 79mph. 28.5 mpg. That is an honest figure which I have duplicated once - on another hot day. In cold weather the economy drops significantly. Warm day = less dense air = less fuel to maintain stoichiometric mixture. I will bet that I misspelled the key word.
:rant:Here in Birmingham; it's the summer formula that gives bad mileage. And, more expensive. Sold only in the Birmingham metro area. Atlanta has a formula all their own, too. It seems to me this is just a bureaucratic trick to drive up the cost of gasoline. The summer formula is supposed to cut down on the ozone level. But, if the formula causes the cars to get less mpg, thus burning more fuel, how is that going to alleviate the ozone? (Not to mention that, ozone is produced by deciduous trees in the summer. The ozone being lower in the winter because the leaves are on the ground!:af Thank you. rant......, over:grin:
Since this past fall, my pickup has been getting the worst fuel mileage ever. It's down to 9 -11 mpg driving easy when it usually gets 15-16 most of the time. It doesn't matter if I use regular or premium though it seems like it does slightly better on premium. Since the last fillup a couple of days ago, it is up to 17. I don't get it. o No: I do believe Florida gets the crappiest gas in the nation. When I go to Pa., I see a dramatic increase in gas mileage. Up to 21 mpg.
I haven't noticed a difference down here. My Ranger gets 380 miles out of a tank (16gal) everytime. I don't even bother keeping up with gas mileage in my Buick. If I did, I would be counting it as Gallons Per Mile. I just put gas in it and go. I run Premium in both.
I thought my mileage was down in the Buick but really don't pay it much attn. Like the others said its the price we pay to drive our cars. Yesterday I caught my kid suckin gas out of my Riv with a electric fuel pump. now I know why my mileage seems down.
