must b all those hooters girls that try to pile in the back......

 

Oftentimes I get exactly 20mpg. At about 330 miles per tank at 16.5 gallons. I think alot of people tend to have a heavy foot from time to time...like every time it's necessary to accelerate...lol I don't drive like Grandma, and I drive about 70% city, 30% highway.

 

Thanks for that checklist, itgogitrev.

I'm at 42,000 and replacing the filter comes at 45k, so I'll probably get that replaced today when I stop into the dealership. They also have a suspicion that my fuel gauge is wrong. The service guy said "I see it all the time on these cars." Any one else ever heard of that? Or is he feeding me some sh-t? He was like "besides the air filter there's nothing else I can test". He also mentioned "the fuel filters in our cars never get changed."

Anyways, to test if I have a bad fuel gauge, since I'm at just above 1/4 tank remaining, I'm going to fill it up. I should be putting in close to 15 gallons if the gauge is correct.

lol, I'm at 1/4 tank left and have only gone 170 miles... sucks!

Actually now that I think about it, the last time I filled up, I paid about $70 and the needle was pretty damn close to Empty. Premium gas out here is about $4.85. That means I only put in 14.4 gallons. So I guess he could be right and my gauge is off by 6 or so gallons? I'll do a MPG test next time...

 

^^^ I fill up at my gas light. Usually 16.5 gallons. With 100% city and a heavy foot I get between 260-280 miles depending upon the tank. So ~16-17 mpg.

 

Amsoil or K&N

Im getting about 12-14 mpg normal driving... about 70% city 30 highway driving

my car is stock besides z-tube w/Amsoil drop in filter, and Fast Intentions HFC

i have replaced Air filter, Fuel filter.. Tire pressure is at 35psi, Spark plugs i have cleaned but have not replaced and im still getting the same mpg



BTW my G has 39K miles

 

wow thats horrible gas mileage...i drive about 90 highway nd 10 city and i consitatnly am getting around 215-220 to a half a tank so im averaging bout 21ish. this past weekend i drove to PA and got 24 mpg with cruise set at 75. btw its an 2003 6mt completely stock. i do acclerate hard too

 

My air filter, tire pressure checks out just fine. I'm going to do a solid MPG test this weekend on my 600 mile drive. It'll be a costly experiment. Hopefully I'll get it figured out soon though... If I'm not getting AT LEAST 18 per gallon, I'm leaving it at the dealership, it's under warranty. That's just ridiculous... I have a feeling that's how it's going to be though.

 

When you think about it, there should be some recourse from the manufacturer if you can't at least get close to the EPA ratings. (Obviously I know this would never be the case - call it wishful thinking)

Consider this:

100,000 miles driven at 17mpg (me) = ~5882 gallons of gas

100,000 miles driven at 14mpg (Beebo) = ~7143 gallons of gas

100,000 miles driven at 30mpg (Civic) = ~3333 gallons of gas

At $5/gallon, Beebo will pay $6,305 more for his car than I will over 100,000 miles, and $19,050 more than a 30mpg Civic owner.

I'll "only" pay $12,745 more than the Civic owner.

 

welcome to the 13mpg club, im just happy im not the only one haha

 

i think G35C only has like 15 or 16 GAllon tank right? how did you get 20?

 

that sounds about right. between 280 miiles Per Tank

 

It's a 20 gallon tank, says Edmonds and my service guy at Infiniti. I suppose my manual would say also :P

Also according to Edmonds, at my current mpg (14) at least I'm over the "worst"

Best Fuel Economy: 23.2 mpg
Worst Fuel Economy: 13.3 mpg
Average Fuel Economy (over the life of the vehicle): 15.7 mpg

Ouch. Although mine is a 2006, not sure how much difference that would make, probably minimal.

 

i'm averaging 300 miles/tank 04 5AT, but last time i had a road trip driving 1800 mile road trip i was getting 100miles every 1/4 tank. So rough estimate 375 a tank because usually the last 1/4 tank goes quick for me..... i got 68k on my odometer, and I drive like there's a brick on my shoe.

 

20 gallon tank? when my gas light comes on I drive like another 15 miles and I'll fill my tank until the gas is at the brim of my gas tank, where it spills out a little and I stops at 16.5 gallons

 

i get about 16-18 mpg .driving fast with 20s......78k on the obo........longest highway trip i went on was 100 miles round trip......but i did notice my mpg was up on that tank........
