You're welcome. Thanks for your service. I'm not an American but I call the US home.

 

At 6:22 AM I posted that your oil temp is normal.

Top off your tank every 1/4 drop, to slowly start raising your average octane.

 

All studies I've read so far is E10 has a reduction in 3-4% in fuel economy. E0 vs E85 on the other hand, is night and day difference. It's actually cheaper to run E0 than E85 if calculating MPG (for cars that supports flex fuel).

By the way, if you guys want to find E0 gas stations just use this app.

For me, I can get E0 91 or E10 93. They both wash out in performance and MPG, ethanol vs octane battle. If both are 93, the decision is easy.
Most E0 gas stations are groceries stores and non-brand gas stations. God knows if they're just false advertising E0. I usually stick with BP, Shell, and Chevron. Don't gas stations get incentives from the government for selling E10/E15? Why would they sell pure gas, which bothers me. I'm sure they can care less about the reliability of our cars.

 

They charge $.75 cents more a gallon for the E0.

 

Sorry LexVan I missed it. I do have Chrono. It was in the high 80s last night so that may be a factor.
Thanks for imput. You seem to contribute lots of useful
info here. I just want to know from the picture how you reach the pedals.lol

 

Yeah, ethanol isn't energy dense and will require more gallons per mile. But oxidizing fuel is easier when your mixture is already oxidized (as ethanol is a little). So that complicates things.

I don't know if companies (probably not gas stations) get government incentives. But given the lobbying that the petro companies have in Washington, who knows how they pad their income statements.

 

The break-in rules are U.S. rules only. In the ROW the break-in rules are - more-or-less - drive the car thoughtfully until the engine oil and water temperature are in the operating range and then drive it like you stole it.

There are many threads on this topic and probably more on the 'vette forum.

As LexVan wrote. 220 +/- 5 is very normal for non-Sport mode. Sport mode will drop oil and water temperature. It won't drop like a rock though; it will take several minutes.

On the subject of the gas: you can use 89 when there are no better alternatives. The knock sensing component of the engine management system will detect knock and retard timing to compensate. But, it can't do that until it detects knock caused by the lower-octane fuel coupled with any conditions that exacerbate the tendency (e.g. heat-soak, low-rpm high-load, etc.)

 

We have 91 octane here in CO as premium. There is a station I know that sells Sunoco race fuel. What will that do for me? Just normal street driving-wise. Worth it, waste of money, or it will explode my engine??

 

Unless you've got unusually high compression ratios it don't do anything for you. Race gas is meant for high compression without ignition. Energy density of race gas and 'regular' gas are almost the same. F1 engines use gasoline that's highly similar to what is used in regular street cars.

 

Arthur, you live in the mile high city, you suck and wheeze on the thin air every day, you should know this stuff. At altitude the barometric pressure is less than sea level, consequently a cubic foot of air weights less. The puny weak atmospheric pressure cannot supply an optimal mass of air to the cylinders. This means the peak combustion chamber pressure will never reach levels that would cause 91 octane fuel to knock. Just be as happy as you can in your low horsepower world.

One consolation is the better gas mileage you can attain when cruising along the highway.

 

Thank you both for the info. Way smarter and more informed than me. Saved me money from trying it.

This spring I've been wheezing and coughing from allergies! Never been allergic to a thing in all my years (50). Move here and bam. Apparently Denver atmosphere/pollen do a number on some people.

 

it would be nice if they sold premium without corn in it. There is a gas station up the street that sells 89 octane without the corn. The alcohol, made with corn that could be used to feed starving Latin Americans, costs more than the energy it provides and it will destroy boat motors. The BP station that sells the 100% real fuel sells it for less than the dam corn mixture. I would love for them to sell the same non-corn fuel in both 87 and 93 octane but the *** wypes in DC are way too smart for us and they know what is best for us surfs. It is a frustrating state of affairs and prices always go up as companies have to adapt to the corrupt ideas of those in DC.

I use the non-food gas for my leaf blower, power washer and boats (I learned the hard way on the boats). For my 911 I am forced to pay about .45 - .60 per gallon more for the 93 octane and it will contain alcohol.

The DOE (energy) was trying to produce jet fuel from algae at one time (not a safe bet) and the fuel that they came up with was about 6 times the cost of what can be drilled for-it did not pan out.

Eventually someone in the private sector will find a good alternative to fossil fuels if there is money to be made. In the meantime I would like those Prius driving a'holes to quit trying to be some kind of pace car and example for me. Most people have no idea what it takes to make electricity or batteries.

Pure gasoline is the best.

 

or is it serfs?

 

Why not just go to Shell? Their premium gas (Nitro+) contains no ethanol.

(On further research I realized this is true only in Canada)

 

It is. Good rant, and on point.

Here's a related question for the group:

Fresh 91 without Ethanol? Or 93 with, that's been sitting?

Where I am, it's hard to find 93. BP still has it, but the only BP stations left here are the sketchy ones they couldn't sell. So I can get fresh 91 from the local station that's busy all the time (and so goes through their gas supply more quickly), or get 93 from a station in a part of town where nobody would buy 93. I have no idea how fresh it is. But that's what I've been doing.
