Regular vs. Medium gas in Base

[Bowlsie]

Dude! How much is regular octane per gallon in Canada? You must be paying around 3 bucks a gallon.

[ragingfish]

Those are litres and Canadian dollars...

[ragingfish]

Mostly litres, but some places do use Canadian gallons from my understanding...

Got gas in Tilbury not too long ago and it was in litres. Of course, that is in Ontario. Who knows what the rest of the wacky Canadians use. What exactly is a Canadian gallon anyway?

Canadian / US Gallon ComparisonConvert Canadian gallon to litres: Multiply number of Canadian imperial gallons by 4.5. Convert Litres to Canadian gallon: Multiply number of litres by 0.22 The Canadian gallon is based on the imperial quart, which is one quarter larger than the U.S. quart (four Canadian gallons = five U.S. gallons) Note: Measurements are approximate for easy conversion.

What it comes down to is I made an error. I intended to say, "those are canadian dollars and litres," but someone came in asking me to pick up a gallon of milk, so I got my thoughts crossed.But I heard someone on here making reference to fuel and canadian gallons...

Hmm...last I checked, my TI85 didn't have a Canadian/American/British gallon convert button. Therefore if the good people at Texas Instruments don't deem it necessary for me to toggle between them all, I'm just gonna swipe my debit card and fuel/gas up wherever necessary. Can't say I'd sleep any easier one way or the other. But this is amusing.

There are only two types of gallons: Imperial, and US. Imperial is used everywhere else in the world, including Great Britain and Canada.Remember -- the U.S. is the only country that does not currently use (and most likely will not switch to) metric (damn us!!!)

[ragingfish]

Already know and use it whenever I can...but one can only do so much in a society where you have no choice but to use non-imperial systems...

My gosh, does someone have to send you two to your corners?!?

BTW, not only are Imperial gallons different than US (160 oz. vs. 128), so are the quarts (40 vs. 32) and (little-known fact) the ounce! (US is ~ 1.04 Imperial) Thus the gallon conversion is not 160/128 = 5/4, but 4.54/3.78 = 6/5.BTW2: We have been officially metric in Canada since ~ the early '80s, but for many years there were some maverick hold outs still pumping gallons, and anyone over ~30 is still likely to think MPG re fuel economy, rather than the official "litres/100 kilometers"

quote:Another thing, if you run your vehicle down to where there is no fuel hitting the sender and go to put some more back in that is a quick way to kill a fuel pump. What happens in this case is the nice cool fuel hitting the already warm pump. Blammo! It's kinda the same principal as say football practice on a 100 degree day and then you hit yourself with a 30 degree chug of Gatorade. Can cause the ol heart to give out. Just throwing some save your money in the long run advice. If I drive around with a gas can until I run out of gas, the gas in the can will warm up. If I drive until I am low on gas, and then go to a gas station and fill up the tank with nice cold gas from the big underground tank, then I am putting colder gas against the warm fuel pump. So, it sounds like the when on a long drive and need to get gas, people are supposed to let the car sit at the gas station for a period of time before putting gas in to not risk "shocking" the fuel pump. Odd that there's nothing in the owners manual about this, and nobody has posted here about failed fuel pumps. Sorry, I'm not buying into the thermal shock risk.

[MadBill]

You're right, joatmon. Fuel pumps are designed to handle any slight thermal shock that might occur. Most cars have return systems, where hot fuel is continually circulated back to the tank, so on a cold winter day a complete fill would similarly "shock" the pump. Any number of electrical components have it much tougher, e.g. underhood, where running through a puddle on a hot day could take the temperature from 250 + to 70 in an eye blink.There is a slight risk factor re running the pump on fumes, in that it is cooled and lubricated by the gasoline. I used to be involved in Showroom Stock endurance racing, and to be competitive it was necessary to run the cars right out on every tankfull, to the extent that it was stumbling and sputtering for a couple of laps. This did result in a higher failure rate on the pumps, but rest assured the Vibe is designed to not self-destruct from an occasional controlled run to empty!

okay i have a base with 93 octane and gt plugs i have not noticed a difference. i havent done exact measuring but i always top off my tank and drive till the light comes on and my mpg seems the same.topping off has never thrown a cel in fact my cel didnt come one when i unhooked the first o2 sensor(car idling not driving but it still seemed kind of odd) so i'll vote against it having an performance effect.

[Lancer]

The higher the octane rating of fuel the slower it burns... ...On hot days or under less ideal conditions, your motor begins to knock. A knock sensor picks this up and the computer retards the timing: this actually reduces horsepower in your engine. If you are running high octane fuel on a hot summer day in traffic, for example, when you hit the go peddle you have less chance of knock occurring. You are running at full power instead of reduced power due to knock.________________________________________________________________Taken from "Dispelling the Myths" 'The Truth About Octane', August issue of Modified Magazine.
