G70 Gas Range/ Full Tank

[Edmguy]

So @NLJ had me intrigued so I decided to give it a shot.

I drove until I had 4km to empty (so likely 2-3 liters left as I have hit zero before but wasn't interested in pushing it). Then filled up using @NLJ 's technique. Here is the result:


So I was able to overfill it and no fuel spilled out. Now that said, I don't think this is something I will do on a regular basis as it was a pita and I don't want to chance spilling fuel over a few extra liters.

But it was obvious driving yesterday that I had extra range as the gas gauge was still showing completely full after 75km:

And I thought California gas prices were high

Don't cry too much for the price of gas in Canada. At a quoted price of $1.30 C, a gallon would cost $4.92 C. And that's the equivalent of $3.65 US. Pretty close to what we're paying in the Seattle area. The above is assuming my math is correct. Feel free to take a shot at my reasoning...

And then there's this...

Overfilling the gas tank can cause liquid gas to enter the charcoal canister, or carbon filter, which is designed only for vapor. Gas in the system can affect your car's performance by causing it to run poorly, and damage the engine.

Worth pointing out I am in Edmonton, AB which typically has the cheapest fuel prices in the country (must have something to do with all the oil we have in the ground...)

Vancouver, BC on the other hand right now is pushing $1.90 per liter for premium. That would is about $110 to fill the tank! Summer vacation in BC is going to be expensive this year!

Re all the replies in this thread, the real answer will only be determined by someone filling a tank (G70 or other model) to the brim from an EMPTY tank. NOT going to be me to do it. I've been using the 1 extra click on all my fillips, but I'm switching to (pardon my french), pulling it out when the pump shuts off.

WOW, now you're talking about $7.19 US in Vancouver although regular must be less.. A lot of Canadians north of the border of Washington drive across the border to fill up. Don't know if they fill up jerry cans as well.

Lots do bring jerry cans too. I think the area is about $1.70 for regular which would be about $4.80 US a gallon. Also I calculate the premium price at about $5.35 US a gallon, not sure how you got $7.19 - I am using exchange of 1.34 CAD to USD and 1 liter as 3.78 US gallons.

Not sure what you are expecting for a real answer. @NLJ just mentioned that the tank is larger than specified by a decent amount and it seems to be true. I tried it as shown above, but that said I don't think it is worth the hassle. Are you expecting a scientific test with an exact volume of the tank in liters and US gallons? Don't think anyone cares about that level of accuracy...

Don't bother with him. He'll just argue in circles!

So I got call back from Genesis today regarding the gas range and this was interesting. he asked in what mode I drive the car "ECO", well we suggest that around town ECO is perfect but recommended that on the highway to keep the car in SPORT because if you need to accelerate you don't need as much acceleration therefore, using less gas. make sense?? Today driving on the highway to the airport on ECO ( this was before I got the call) I got up to 31 mpg. I will on Friday put the car on sport driving back home to see if this is true. keep you posted. But still 333 miles on full gas of tank. doesn't add up

That's a half truth. Yes the faster you get up to speed, the quicker you can coast or cruise but Sport revs higher and tends not to shift to 8th gear and holds on to lower gears longer so you're cruising at 2,000+ rpm instead of 1,200rpm.

I don't want to break up the party here but running with a low gas tank even once can cause irreversible damage to the fuel pump.

This is more important than ever with a direct injection engine as it needs really high pressure.

An adequate level of fuel is needed so the pump doesn't have to work unnecessarily hard to draw in in fuel. Extra fuel around the pump will also provide the pump with cooling and lubrication.

It also recommended to not go below 1/4 tank of gas. Also, less problems with sediments this way.

"Topping-off" the fuel is also a bad idea as that can lead to engine damage.

Seems like perpetuation of old wife's tales.
Modern vehicles don't have weak pumps like older vehicles. Technology didn't stand still...
Back in the day, fuel pumps were mounted conveniently and not always in the lowest spot or inline like it should be.
And if you can't drive below 1/4 of a tank, that's a lawsuit waiting to happen.
Components like these are over engineered nowadays to protect manufacturers from consumer stupidity and high failure rates.
As far as the topping off thing, the charcoal canister on most modern cars are above the filler neck facing downwards so you can't flood it even if you tried. If you did, driving and using up fuel creates a vacuum effect that sucks out the fuel from the canister. Filling it to the brim and parking it is the danger!

Edmguy on Post 25 above reported that premium in Vancouver costs $1.9 per liter or $7.19 C per gal. According to my calculator, that's $5.34 US so we agree. My calculator says a US gallon is 3.7854 liters.

And hey, I'm not anal about how much fuel can be put in a tank if you fill it up to the brim. All I'm saying is it's impossible to say how much extra fuel you can add unless you start with an empty tank OR fuel pumps automatically shut off at exactly the rated capacity. If the latter is the case, any fuel added after the pump shuts off is extra fuel above 15.8 gal for the G70 or above 20.3 gal for the G80. Not rocket science math.

Canister aside, topping off is still not a good idea. Many cars will throw a code if there is not enough head space. I've done that a few times.
I don't usually go below a 1/4 tank for other reasons. Seems like the times I stretch it out, when I really do need gas it is raining hard or 15 below zero. I prefer easy.

I'm with you all the away. Fill it at 1/4 remaining.
