done properly, not really. most cars can handle a low percentage (maybe 5-10%) ethanol in their gas without harm. It will, however, reduce gas mileage.
Some with older cars don't notice a difference when combining ethanol with gasoline. 10% ethanol mixed with gasoline is a safe amount to use for perfect results.
the engine in a 84 ford laser is not ethanol compatible & will run like a sack of crap if you use fuel that contains any ethanol
any car should be able to run on e10 10%ethonal. I second that comment. I have been driving my 1968 Bug for 4 years on 10% gas alcohol blend with good results.
Gasoline is good for cars and bad for drinking. Lots of people inhale the chemicals and are sent to a vet because they could show characteristics of an animal
The two biggest issues with ethanol as a fuel are:Ethanol is polar and therefore a much better solvent for some materials than gasoline is; this could result in things like seals and tubing swelling or even dissolving if ethanol is used in a fuel system that was expecting a more or less completely non-polar fuel like gasoline.Ethanol is significantly more hygroscopic (absorbs moisture from the air) than gasoline is. Moisture in the fuel is bad for lots of reasons, including potential rusting of some parts within the engine.Another thing to be aware of is that the energy density of ethanol is about 1/3 lower than that of gasoline, so using ethanol instead of gasoline will result in reduced fuel mileage.Gasoline mixed with 10% or less ethanol is generally okay to use in modern gasoline engines. (Consult your owner's manual to be sure.) Gasoline with more than 10% ethanol can cause problems in vehicles not specifically designed for it (Flex-Fuel Vehicles). FFVs generally state the maximum percentage of ethanol they're prepared to handle; this usually takes the form of a code like E85 (up to 85% ethanol, with the remainder being gasoline).I don't know specifically what your Jetta was designed to handle, but it's likely some problem related to the above.
It is possible for the check engine light to come on in a Pontiac Transport when using ethanol gasoline because it burns hotter than other gasoline. The check engine light might also come on if the oxygen sensor is bad.
I have been running my car on E10 for as long as it has been available without any bad effect. The rumour that ethanol was bad for your engine was started by the fuel companies because they lose money when you are not pumping CO2 and CO3 into the atmosphere. In Australia they even managed to have a maximum mix put in place, 10%. In some of the older cars ethanol did have an effect on some of the fittings in the fuel system but that problem has been overcome now.
Using ethanol-blended gasoline in lawn mowers can cause damage over time due to its corrosive nature, especially in small engines. Ethanol can absorb water, leading to issues like corrosion, clogging, and other fuel system problems. It's recommended to use fuel with minimal or no ethanol content for optimal lawn mower performance and longevity.
Ethanol is primarily used to oxygenate the gas and replace the chemical MBTE, which pollutes groundwater. HOWEVER, since most ethanol in the US comes from corn, it is important to note that using ethanol in gasoline causes GREATER pollution than just gasoline alone. This is because it actually takes more energy to produce corn based ethanol than is extracted from it. Until better technologies for ethanol production are available (e.g. algae), it is best for the environment to avoid gas containing ethanol if possible (some states mandate it). The idea in more recent years was to reduce dependence on foreign oil (most of ours comes from Canada, a smaller proportion coming from the Middle East), but the end result has been an unfortunate upward swing in global corn prices which affects the people who actually use corn as food.
No, its bad for your engine Sure you can mix them as long as your vehicle has a flex fuel engine. You can also mix then in a non flex fuel engine as long as you do not mix more than 10% ethanol with plain gasoline.
Try a different grade of gasoline. Late eighties cars have a hard time with the ethanol blend of fuels. If it is high milage engine compression builds up due to carbon which raises the compression ratio. Wait till engine is cold and start run a tank of premium and don't use ethanol blend. Change O2 sensor as a bad reading will send bad signals. Start with this and see if problem is cured. Changing plugs wouldn't be a bad idea also. This fallacy of plugs lasting for 50000 miles is just not true.
The best website that lists station by state then city that is user-maintained. I carry a ethanol tester with me, along with a small bottle of water and a cup to make it easy to accurately measure the ethanol. You can get a tester at the related link. Some stations can only get premium in ethanol-free, so, pay attention to the listings. Here in Saint George SC, two stations have zero Ethanol, the Citgo offers all grades, another station, Mystic, only offers zero Eth in 91 octane because the regular is pre-mixed (that's bad!) in Augusta and trucked 2 hours over to my little town.
