gasoline with ethanol
Do you guys know if using gas without ethanol on colder temp increase the MPG of the GLK or it will just be the same with the ethanol blend gas?

Using any ethanol mixture will decrease your fuel economy. Ethanol has less energy and heat content compared to gasoline, so to compensate for the reduced energy, your engine has to burn more. Plus, ethanol is extremely corrosive (hence why all exhaust systems have to be stainless steel).

I would never do it, just my 2 cents.....

I would never use an ethanol mixture in my GLK, only premium:y

I don't think premium gasoline adds alcohol. Higher grades like 94 usually add methanol to increase the octane number and tend to burn hotter. Higher octane fuels are generally used with high compressor engines, because they have a more predictable flame front (to avoid knocking)
Keep in mind octane number differs between Europe and North America |
I suggest a controlled test. Say five tanks of each computing MPG, or MPLiter, and calculating the results manually. Not relying on the built in computer. Personally, if I get get real gasoline, no ethanol, I would.
For once I agree with the rabid tree huggers: Turning perfectly good food into a bad fuel is DUMB! and uneconomical. End of rant. Keep us posted. Wayne |

With regard to Fuel Requirements is there a statement in the GLK Operator's Manual: "Reformulated gasolines (RFG) and/or unleaded gasoline containing oxygenates such as ethanol, TAME, ETBE, IPA, IBA, and TBA can be used provided the ratio of any one of these oxygenates to gasoline does notexceed 10%; MTBE must not exceed 15%." And, the subject ethanol is eagerly discussed a number of times on the forum, with a lot of more - or less qualified statements. :bow: |
great...another BS to worry about. So I guess the GLK will be needing a change in diet soon. I"ll try to use the 94 octane without the ethanol mixture and see what consumption I'll get but that will be for next week as I just filled the car with the ethanol mixture gas (91 octane)....I hate how these really smart corporate persons do something like these to ravage the consumers who buys there products.
When engines that runs on water will be invented they will say "spring water only" rather than "distilled water" go figure. |
With 10% ethanol I would say so many other factors are having an impact on the MPG, like road conditions (snow, rain, surface), temperature, where etc., that it might be hard to say any change was the caused by the blend as such.
The change of octane will most likely be the cause of any increased MPG. My experience with a 85% ethanol car thru 3 years was a decrease of the MPG of approx. 28%. |

This ^ ! Where have you found a non-E10 fuel? :crazy:

Here is Canada, regular gasoline is E5 (max 5% anhydrous ethanol), premium unleaded gasoline is 0% anhydrous ethanol. :smash:

In Alberta, most gas stations, the highest grade for premium is 91. I have seen some Husky gas stations selling 94, but like I said before that has Methanol blended in to raise the octane number. Furthermore, at Shell stations, it often clearly states on the pump "Regular is max 10% anhydrous ethanol," Silver (89) is max 5% anhydrous ethanol"

We saw a number of stations in rural TN, AL, MS & LA recently. They all had large signs touting their Ethanol/Alcohol free gas. I actually bought some 89 octane ethanol free gas in LA.
Wayne http://pure-gas.org/index.jsp There are even a few in Maryland. Wayne |
Interesting! I like the idea of ethanol free gasolines... that junk has been forced down our throats by the corn lobby of ADM Inc. It not only wears down our fuel systems, it significantly reduces our fuel mileage, attracts too much H2O, and increases the cost per gallon by 12 cents... and the clincher, it does very little to help the air, if anything.:X
|
It's worse than that. ADM, Inc. isn't alone. The rabid tree huggers are now admitting that it takes more BTUs in than BTUs out to produce. Gasoline isn't the only thing that costs more. Food prices are jacked up because we divert food into our fuel tanks. Don't get me started. :D

I knew there was a reason to visit Alberta. It's been too long. Dusting off the maps. Eh!
