Yes.
Almost all modern gasoline contains a ethanol.
there's also a complex additive package that's supposed to keep motors clean, and help out with smog.
it works alright, but you cant leave gas sitting unused for more than about 2 months before it goes bad, starts to change color and turn to varhish
Yes
yes
Premium is ok
NO.. it does not need premium gas.. You only have to put premium gas in a car which recommends premium gas. I would recommend a fill up with some mid grade gas atleast once a month...
In most areas. yes. There should be a sticker on the pump saying if it has ethanol in the gas.In most areas. yes. There should be a sticker on the pump saying if it has ethanol in the gas.
You don't have to remove gas, just add good gas as ethanol gets used up.
premium
Depends. Sunoco has it available, but so does Shell. It is up to the dealer if he wnats to put a pump in for it. Persoannly, I think there will come a day when most stations will offer it has a third alternative to 87-89-91 octane. Beats the crap out of ethanol added gas by a wide margin. Better mileage and better performance.
Unless it calls for premium gas in your owners manual your wasting your money using premium.
Premium gas is better!
Premium gas of course for best performance
pump gas would recomend premium
