Planning on getting a G35 this summer from my econo civic, so definately have some gas questions....

1) Milleage / full tank?

2) Price / full tank (i know it varies but avg)

3) I believe g35 requires 91? my friend has a 330ci and downgraded to 87, i think he's nuts but he says theres no diff , anyhow anyone tried this? maybe not all the way to 87 but 89...

 

our tanks hold 20 gallons.. i use premium.. price ranges from 3.35-3.39.. u do the math..

 

If you need more than 20mpg from a car, please don't buy a G35.

 

Let me break it down in Canadian measures.

I am getting average 12 - 12.5 L/100km and I drive pretty hard most of the time. With gas hovering close to $1 per litre these days and $1.15 for 94 octane at Sunoco, I am putting in about $70 per full tank (60-65 litres) and I usually go through a tank per week.

Hope that helps ...

 

Your question will only give you a very rough idea of fuel economy. Any measure other than litres/100km or mpg is useless.

Safe to say your civic will be better but you'll enjoy the G more.

 

As always, a master of understatement .
I usually get 10 km/L. 80% hwy.
Nice move up .

 

What year is the civic? Are you going to trade it in? If it's an older one and you don't have any more payments on it, I'd say keep it and use it for a daily driver and get a G35 for play and for those days that you want to make your "everyday" a little bit more exciting.

 

$60 to fill up at $3.57, 17 gallons

Same here. I'm getting an average of 10.65 L/100km, this is with 80% highway driving.

 

I normally use premium but didn't use it during the icey and snowy months this winter. I didn't figure it made sense to burn the more expensive gas when defrosting the windows. I think the manual says at certain altitudes you can use as low as 85 octane.

I can't say I noticed a difference between 91 and 87 but how often do you floor it during the winter? I dunno if I ever got above 3000-3500rpm.

About 3/4 of a tank (according to the guage) is costing me close to 60 dollars now (for premium).

 

NetCBC,
In my M, I get from 7 to 10 km/l depending on speed, while my Civic gets about double that. It sips gas by comparison.

My G-Sedan got between 7 and 12 km/l and the coupe got about 8-10 km/l.

I hope you're not changing rides on mileage expectations, because you won't do much better than the Civic, and gas mileage is not the G's and M's strong suits.

I used premium on all my Nissan/Infiniti VQ's for optimum performance, but some can handle lower octanes if economy and not performance is what you're after.

This summer I actually considered getting a 30+mpg car to offset gas prices, since I drive a lot. I did the math and without boring you I would have saved about ~$1000 a year, but trading my G in would have cost me about 5k, so 5 years to break even. I guess the point is it wasn't worth it for me, and frankly I figure even at $5.00 a liter it's still less than milk, so whatever.

Since you're thinking of going *from* a civic to a G it's a little different. Just think of it this way, on top of ownership costs if you drive 10k km a year you'll pay about $800 extra for gas. $800/year extra to drive a G instead of a civic, good deal imo!

 

I can honestly say that the G35 uses the least fuel of the cars I have.

 

$3.57? Holy crap! I guess I just found a plus to living in the SE

 

LOL, my M has a 76 liter fuel tank and our premium today is about $1.07 per liter. That's more than $81 CAD to fill it from empty.

The Civic on the other hand has a 50 liter tank and takes cheaper $.97 regular fuel. It 'only' costs about $48 CAD to fill from empty.
