Why does the gas pump on Exxon/Mobil gas have a sticker that says 10% Ethanol.? If this is true, why do we pay full price for gas? Should we not pay 90% gas + 10% ethanol and they should have a breakdown of what ethanol costs? Thanks

ed replied: "Ethanol is not cheaper than gas. It's used to reduce consumption of oil/gasoline."

54 and still learning replied: "because it is blended with 10 percent ethanol.as why we pay the same for 90 +10,you can get 100 percent gasoline,but it is more per gallon."

Q.T.π Spanky replied: "Years ago the gasoline companies came up with gasohol, a gasoline/ethanol mixture. They promoted it as cheaper than straight gasoline. Fast forward from the late 70s early 80s to just a few years ago. In order to burn gasoline more cleanly and reduce emissions ethanol was added and the gasoline companies had to charge more for it because the government made them put it in. I bet most people forgot how much cheaper gasohol was."

bob the mechanic replied: ""QT is correct! except as a further note, ethanol in gasoline is extremely hard on fuel pumps, injectors, and fuel pressure regulators. this is a fuel that creates small run-ability issues. i wouldn't recommend continued usage in your vehicle."

Oiler replied: "You don't say where you live, but it's likely that you live in an RFG area. The EPA mandates through the Clean Air Act that certain high smog areas of the country (PADD's) must have an oxygenate in their gasoline to promote proper combustion. Ethanol is the oxygenate of choice, now that the gov't has removed protections from using MTBE, which has a bad habit of contaminating groundwater. PADD areas are most of the Eastern Seaboard, West coast and densely populated midwestern cities. If you live there, you've been running ethanol or MTBE since the mid 90's. Ethanol is a good additive for gasoline. It increases combustion efficiency and octane. All makes of vehicles since the mid 90's have been able to run ethanol fuels without problem. Some companies used methanol for a while and it does mess with rubbers and plastics, but ethanol is less destructive. I have driven 3 cars over 100,000 miles each on ethanol added gasoline and never had a fuel related issue with any of them. As for a breakdown, do you have a breakdown on what wheat costs in your bread? How much the dairies saved by limiting the butterfat in your milk? The cost of beans in your chili? The cost of the aluminum castings in your car? You pay for a finished product."

I put 10% ethanol gas in my lawnmower and now it won't idle or run worth a darn.? I just read up on the 10% ethanol gas and the differences between straight old fashoned gas and the newly available 10% ethanol blended gas. I don't understand how this could be a problem. If anything it seems that ethanol should run the same or maybe marginally better then gas? So what's the deal? I was running my mower it ran out of gas, the same gas I've had in my can for several months and was pre-ethanol, then I filled it up with new fresh from the station gas (10% ethanol ) and the motor just couldn't even out, it races then chokes and races and chokes and just won't get up to speed. Coincidence? Or a bad omen for ethanol blended fuel and old motors? 5hp Briggs and Stratton at least 8 years old. Thanks!

Pengy replied: "sound more like by running it empty something choked up the filter or more likely the float in the bowl is hanging up"

duster replied: "lawn mower engines, do not have that much compression like a car engine does. The mower that old will run, but the needle valve adjustments will need to be adjusted for better preformance."

Charley J replied: "My guess is that using E10 in an eight year old lawnmower has probably dislodged some debris in the fuel system and now it clogged up the carburator.Ethanol is also a solvent and older enginesthat arn't used to it may suffer similar problems.I woul drain the fuel tank, then fill it with regular gas.Clean or replace the spark plug.Pull off the air cleaner,and get some gumout spray.After you get it running slowly spray some gumout directly into the carb at high RPM AND TRY TO AVOID stalling the engine.This may help get things back to normal.Good luck."

Todd B replied: "First off make sure that you didn't suck any dirt into you carb. A very small grain of sand can make the carb go nuts. As far as ethanol, Briggs and Strattons stand is the E10 is not recommended, but it can run on it. E85 is a no. Ethanol burns hotter and is an alcohol. Alcohol and the older plastics and rubbers don't get along very well. I have seen this a lot in chain saws and weed trimmers."
