Guys- Had my 08 lakeshore slate G35x for two weeks now and am in love with the car. Really enjoy this site, too. Lots of great info and ideas. I've seen a bunch of threads on the gas folks use but I have a slightly different question. Is there any train of thought on when to fill up your G? Is it better to burn the tank to almost empty and then fill up or is it better to keep the tank filled? Does it matter at all?

 

you should never run a tank dry, I haven't really looked into on these cars in particular and how the pump is positioned in tank, but if you run it low enough that the pump doesn't pick up fuel and sucks in air you over work the pump and fuel also lubricates the pump so if you run dry the pump is on with no lube so that's not good either

 

What he said , also alot of crap sits at the bottom of the tanks and you don't want most of it getting sucked up.
I Usually fill up every week no matter how it is unless it's at 1/4 left

 

I would say its all up to what you want to do. Most of us will run it until 1/4 tank left then fill up. I would also agree with what black_gst said too!

 

Fill up frequency......too often =(

 

I'm at the gas station every week.. if u can help it.. don't run it until u sucking fumes

 

I fill it when the low fuel warning comes on, or sooner if the price of gas drops enough to entice me to pull in for a fill up.
There is still 10 litres of fuel when the low fuel warning comes on so your fuel pump is still 'lubed and cooled' and you're not getting into the 'dirty' fuel (if there is any) either.
In the winter I keep it about 1/2 in case of emergency. Don't want to be stranded out in the cold.

 

yeah no joke! lol

 

As has been mentioned, you're perfectly fine anywhere within the normal range of your fuel gauge, you'd most likely get freaked out by being below E and fill it up before you'd risk any kind of problems anyway. That being said, I have run my car COMPLETELY out of gas on at least three or four occasions and suffered zero effects (I do only use quality gas from respectable stations though). If you are storing the vehicle, you'll want your tank as full as possible to minimize condensation. If you are truly worried about fuel economy, you're actually better off keeping your tank below 1/2 way (saves weight) and just filling up twice as often.

More than likely though, you're just over-thinking the whole matter. Relax . . . and enjoy your G!

 

i just fill up after it hits 1/4 or less

 

Low lite = wallet lite.

 

If possible, I usually wait until the screen blinks "- -". I'm not worried about low-fuel issues. In my case, the blinking just means i still have at least 3 gallons left in there. That's still a lot in my book and should not cause any problems.

 

I've done that twice, with miles left: ---
Got me a little nervous It seems like when I get to about 16 miles left on the range, it goes to ---. I think there was maybe a gallon left.

 

I fill up about 4 times a week!!! Lol

 

Are you serious? If i was even filling up 2-3 times a week..i would have a 35 MPG car
