unleaded Gas

[cmdmfr]

I have a 2011 Chevrolet Impala and it said that it can run on ethanol or gas mixed with ethanol. I was would like to know if the car can also run on pure unleaded gas what the outboard motors are required to run on. The only difference I see is it is pure unleaded and does not have the 10% ethanol in it

Your car will actually run a bit better on "pure" gasoline with no ethanol content as it is more dense in energy. Somebody more knowledgeable than myself will be able to give you a more detailed explanation. I don't think "Unleaded Gas" (as you have put in your title) has anything to do with gas with ethanol as it is not leaded gas.

It will run a bit further on pure gasoline, that's the energy density)

Depending on engine management software it will run with more power in ethanol.

Saab 2l ecotech turbo engines went from 210 to 250 bhp on ethanol.

SWEET.

This doesn't sound right. Very few engines can run on E85 which is gasoline with 15% ethanol, very few. I doubt your car can run on pure ethanol but I could be wrong. Gasoline with no ethanol will not hurt your car, it is very hard to found around here. I would use it in my lawn equipment that was built before the ethanol started showing up in all gasoline at the pumps.

Only tangentially related, but you'll probably find both E85 and Ethanol-free gas to be less economical.

We have two vehicles that can use E85. When we got the first one, I tried a full tank of E85. Our fuel economy dropped about 33%. The price is only marginally cheaper (nowhere near 33%) and I've even seen it HIGHER than E10 recently.

Gas without the 10% ethanol should give a better fuel economy (maybe about 2-3% by my estimates), but it's usually more expensive (by more than the 2-3% you would save) and harder to find.

I buy the gas with no ethanol for my outboard, and its a lot more per gallon than what I put into the car

Off topic, but what really bugs me is the diesel fuel I put in my big boat. No highway tax, and yet its much more expensive that what truckers pay

Always try to buy pure unleaded. Marathon is pure.
That is also recommended for 2 cycle engines. By name!

Marathon contains up to 10% ethanol.

We told you that boat was going to be expensive to run and maintain. The marina knows you can't drive to the local truck stop to fuel up so you will pay for the convenience.

Don't think about filling cans and taking them to the boat, your dockage agreement will contain a clause against doing this. Boats must be fueled at the fuel dock for safety reasons.

Anyhow happy sailing, that's a beauty of a boat.

Just to correct an error here... E85 is actually 15% gasoline and 85% ethanol, not the other way around. Most gas stations sell E10, which is up to 10% ethanol.

Just wondering........while we are on the topic of "gas". Does all unleaded gas come from the same "tank" for use of a better term. Eg.....is the gas from Shell the same as the gas from Exxon, Circle K, Costco??? Someone told us that it all is the same gas but my husband swears by Shell and says we get better mileage.

No, the basic refining is the same, but different sellers have different additives. Used to be a big thing back in the day when companies advertised for your business.

Where we live, there are 2 pipelines that bring fuels through the area. Shell operates one and Phillips 66 the other one. Some other branded fuels are trucked in. (Most) of the discounters either have contracts for supplies from one or the other, then may-or may not add their own additives (and locally produced ethanol) to the load of fuel as it's being loaded into the tanker to deliver to the local station.

If you are driving by a gas station and see the tanker driver making a delivery, just ask him where his product comes from. Usually these guys love to have a little conversation and talk about what they do.

I can carry 5 gal cans for the outboard on the dinghy, The big boat has 2 tanks and holds almost 400 gal.. Thats a lot of 5 gal cans

i understand why it costs more at the dock (because they can) and I went in with eyes open... It still bug me.

Huh. E85 is ethanol with 15% gasoline.

The 85/15 mix can be 51/49 > 85/15.

It is the same base fuel from the distillery. The premiums add a pack of additives to give their 'blend'

But realistically fuel is fuel.

Ok what do you want to call a plant that performs fractional distillation on oil. A refinery. It's not refining it, it's distilling it.

Your E85 engine management is not changing the compression ratio to benefit from the 94-96 RON E85 fuel.

An engine that can actively manage compression, especially a turbo will take advantage of the increased Ron to improve fuel consumption.

As far as I know all gasoline sold at automotive stations (not sure about marina or aviation fuel) has been unleaded for many years. Some states and stations still sell 100% gasoline and this should always be used for small engines such as mowers and weedeaters. So far, they are not built to handle using ethanol contaminated fuel. (Again, as far as I know as I'm sure at some point they will be but I think it has something to do with the carburetors/fuel bowls and the gas 'breaking down' when it isn't used for a while.) Cars built at least in the last 15-20 years or longer can handle up to 10% ethanol fuel which is the most common blend at present. There is usually a loss of fuel economy however. In my mid 2000s cars it seems to be 7-10% for highway driving. I've been keeping close track for several years. There is talk of requiring the percentage to be increased to 15% but Ive read many manufacturers and mechanics claim this will cause a significant increase in repair costs. There is also E-85 which is 85% ethanol but it should only be used in engines specifically designed for it. People I know who have these vehicles report pretty poor fuel economy when using it but that's only a small amount of people and they were early adopters. I used to use only 100% when available but the price difference is so great right now I do not for my cars. FWIW, I do not claim to be an expert but I do have some experience and friends/family in related businesses. Hope this helps and doesn't mislead anyone with incorrect information.

Yep, I got it backwards.
