so what kinda gas does everyone use. my friend is always boasting about his v-power with shell. I normally run with BP but will get some chevron or shell if im near one and gas is cheap. does anyone not buy premium?

 

I alwlays run 93 Octane. Always a name brand like Sunoco, Shell, Gulf, Mobil. I stay away from the no-name convenience store brands.

 

At least 91 octane

 

no more than 93

 

what would happen if you had more than 93 octane?

 

The Flux Capacitor would blow.

 

I always use 87 Octane or lower if I'm driving in Mexico.

 

 

why is that???

ps- this is a revival of a really old thread

 

I run 91-93 octane due to the advanced base timing; if I ran stock timing I would use 87 octane as I do in the stock-timed IROC-Z.

 

Lowest priced fuel I can find...don't really care the brand. I've tried them all, high and low, "premuim brands" and "Circle K"/7-11 brands and they all seem to work about the same for me.

87-all stock

 

Chevron 92 every time.

 

BP 93/Premium

 

I've run 89 octane pretty much since I got the car 5 years ago. Very seldom waste my money pumping premium.

 

Too many variables to make general determinations what is the best gasoline. The most important factor is the compression ratio. Generally, the higher the compression, the higher octane fuel is needed. Has something to do with maximizing the efficiency of the flash point of fuel (I'm not an engineer, so I cannot elaborate any more than this).

Fuel definitely has more effect on old carb cars than on the newer FI cars. My old C3 sounded like a diesel when I put some 87 in it (only did that once). Anything under 93 and the car was a handfull. My 96 does not seem to react as much, other than slight loss in power and less fuel mileage.

 

premium always..as for brand, I use whatever station I am near when I need gas.

 

I had just picked up my first vette, 88 l-98 last week and assumed premium was the only way. I might try my next tank w/ regular and see what I notice.

 

Gasoline?

Filled up yesterday 06 Armada LE $76.00 87 regular.
That will last about 5 days, so its 6 fiilups a month thats only $456.00 a month.

Think about it, $456.00 a month the payment on a low priced home.
Or a late model Z06.

Where is this going? All the way to $5.00 + gallon.

26 gallons at $5.00 is $130.00 x 6 = $780.00 a month.

Gasoline is over and its getting very expensive.

How many can afford a gasoline bill of $1000.00 + a month?

Its coming a lot sooner than you think.

Wiether you buy 87 or 89 or 91 is really a moot point compared to wating in line to buy what-ever is available.

Been there, done that...............what-ever it costs.......where ever you can get it.

Wake up America.

 

It more people drove vettes then SUVs then the gas supply would last longer.

On a serious note, I am worried about the gas supply problem. If they come out with an alternative fuel will I be able to convert my vette to it? I really hope so because I love that car.

 

I run mine on 87 octane. It's a stock '86 Corvette with a stock iron-headed L98, stock timing and everything. That's what the owner's manual recommends for that particular year. I think later years may have changed this, and if I make changes to the engine I would definitely reconsider.

On the subject of alternative fuels - I've seen some amount of talk about butanol; it's another alchohol like ethanol or methanol, but with four carbon atoms instead of two or one. It's apparently easier to substitute for gasoline, but not as readily available. See here:

http://en.wikipedia.org/wiki/Butanol_fuel

It is possible to convert a car to flex-fuel if you've got the money. You would need to replace the injectors and other things to make the fuel system compatible with alchohol. I'm not sure if you could reprogram a stock ECU to use a flex-fuel sensor, or reprogram an LSx flex fuel computer to run an LT1 or L98. It may be possible. But there are a few options that I know do work - you can reprogram a stock ECU for a fixed fuel blend, swap in a later flex-fuel drivetrain in its entirity, or use an aftermarket ECU that has flex-fuel capacity. There are a few on the market already, and it wouldn't surprise me if more appear as gas prices climb.

I'd probably want to wait and see if one particular alternative fuel becomes more prevalent, though, as I don't really think that scaling up a Jack Daniel's distillery to make motor fuel is likely to be a long term solution. There's several other methods that I think have the potential to be more efficient, including other ways of making ethanol, but also some other types of fuels.
