Car calls for minimum 91 octane.
Pull in to Chevron.
$1.539 for 94
$1.509 for 91
$1.369 for 87

In two transactions, i put in:
15.600 L of 94
10.322 L of 87
Fill octane = ((Fill 1 octane + fill 1 vol)+(fill 2 octane + fill 2 vol))/(fill 1 vol + vill 2 vol)
=((15.6*94)+(10.322*87))/(15.6+10.322)
=91.21
Cost per L:
$ = ((Fill 1 vol * Fill 1 price per L)+(fill 2 vol * fill 2 price per L))/(fill 1 vol + vill 2 vol)
=((15.6*1.539)+(10.322*1.369))/(15.6+10.322)
=1.471
My realized savings:
savings=(potential cost per L * total volume)-(actual cost per L * total volume)
=(1.509*(15.6+10.322))-(1.471*(15.6+10.322))
=$0.99
I didn't even save a whole dollar :rukidding:

It's called blending the fuel and that's what the dispensers automatically do for you when you pick the mid grades. Yes you didn't even save a whole dollar but think about that extra money the gas stations make because of that...

Thanked the meme but I'd be shocked if an OP with 510 in the username was Chinese or EI.

Or you could just full in the states.
92 is usually ~$0.90 at tulalip

I always fill 94 chevron. I just make sure to barely touch the nozzle when filling. Sure it takes me 5 minutes to fill up my 65litre tank but I get the most out of every gas fill up
Lower mainland fuel taxes are rough. 135.9 at Chevron here when I filled up 2-3 days ago (118.9 for 87).
Go ride a scooter, savings $$$$

I go hunting for loose change around vending machines, pay phones and water fountains too.

there is none other then wasting time, he's prob the type of person that shakes the hose thinking he will get more fuel out of it... The only thing that will do is cause a spill since the automatic shut off of the nozzle won't work when the tank is full.

Fill up early in the morning or when it's still cold. The colder the ground the more dense the gasoline is. When it's warmer out, you're not exactly getting a liter for every liter you pump. Pump on slow speed to minimize vapors when pumping.
That's pretty much all the "tips" I know. Not sure how valid any of this is, I generally ignore all this when I fill up lol. I top it off if it's cheap, or fill when I'm at 1/2 tank. I don't bother slowly triggering the nozzle, I full blast so I can gtfo quicker lol

Not sure if srs. Gasoline is stored underground in 1000's of liters. It would take much more than 7-8 hours for it to change the temperature of the gasoline to make it more "dense". Plus the temperature of gasoline is usually regulated at around 50-55 degrees C anyways. Only difference would probably be summer vs winter filling.

Dont even bother filling up in vancouver anymore. My parents go grocery shopping to bellingham probably every 2 weeks. Fills up moms car there, brings back 5 of 20 liters gas containers, fill up both my dads car and my car. Bingo. If not going to the states, I fill up at superstore using presidents card, saves 6 cents a liter.
^Lol, I heard garbage bags are they whey to go :lawl:

You did not account for the ethanol in the 87 octane gasoline, which is blended with ethanol (has a lower calorific value/energy content). Overall, you've blended gas that is "lower quality" than straight 94 octane gas.

Plus the temperature of gasoline is usually regulated at around 50-55 degrees C anyways. Only difference would probably be summer vs winter filling.
Gasoline sold in Canada is adjusted by an automatic temperature compensator at the pump, so it makes no difference what temperature we buy gas at (the standard temperature of gasoline is referenced at is 15C or 60F.) This pretty much work against us because the average temperature in Vancouver is less than 15C

Those tips you know are wrong.. Each dispenser has something called ATC (Automatic Temp Control) which of course makes sure the temp of the fuel is up to weights and measures standards so you get what you pay for. As well the Veeder Root fuel monitoring system in the ground will go off if the temp of the fuel in the ground has changed drastically.
That being said Chevron is the only gas station that doesn't use ATC and there is no difference at all as long as the dispensers are calibrated every year which they are.

If they weren't raping us so badly for gas I would say the slight premium on 91 (vs mixing) would be fine to cover the bit of extra wear and tear on the pumps toggling more to mix the gas.
But they're assholes so fuck'em :fuckthatshit:

Mixing is how the pump gives you 89 and 91 anyways, that's why it says "may contain up to 10%". If the 87 is 10% and the 94 has none, the 89 and 91 will be less than 10% ethanol.
