Sometimes...the things you say...they allow me enjoy this place whilst typing a whole lot less.

I just connect with the older crowd more. Maybe thats how I ended up seeing the 38 year old I'm seeing now...but thats another thread

To contribute though...I'm gonna reset my trip tomorrow but I dont believe I've ever seen it past 18.1

Telcoman...I dont know I think he works for tornado or something because I just dont get how he does what he does

It's not hard to get great economy by hypermiling, but to do that all the time with this particular vehicle would be a real shame. Fuelly displays the amount that would be saved by achieving 1, 2, 3 mpg more than your last fill-up, and to me it is worth those few bucks to drive and enjoy this car as intended. If all I wanted to do is feather the throttle on long, straight highway journeys, I would have bought a VW TDi and seen 40+ mpg without trying. Meh, to each his/her own...

Data compiled by sites such as Fuelly could help answer OP's question if transmission type is an available discriminator.

That was nice. Lately my posts have been all grumpy old man rant-ish, so this made me smile.

I don't understand people like Telcoman... So proud about using the wrong gas that he actually advertises it in his sig. It like the crazy uncle on SS and Medicaid who claims conservative politics. It defies rational explanation, so after a while you just stop bothering because you only see him on Thanksgiving. And he is family, after all.

Meh. I think my car, or every car for that matter, is a whole lot more rewarding to drive when actually driving it in a way that the design intent supports.

There is nothing wrong with trying to be a little green. I think it's a waste buying the G, driving it more conservatively than my grandma driving a 400K car on the expressway and then putting the lowest octane and cheapest gas one can find. Meh, but to each their own.

Having said that, I got a ride in a tesla yesterday, green can be fun.

green and fun come with a cost.

Never saw anything close to that in my G!!!!!!!!!!!!!!!!!!! You must baby your car big time. Even my light footed wife didnt see anywhere near that good of gas milage except for maybe one or two cycles during a road trip.

telcoman

Yes they do!

I'm just proving much of the misinformation regarding grade of gasoline.that gets posted by many who believe marketing and advertising hype.

Except for competition at the track the use of premium is a total waste of money. But that is just my opinion. I traded in my 06 G35 with 171796 miles and my engine ran just like new.
I did one month tests with 91 and 93 octane and saw no increase in MPG.



I've saved thousands of dollars in using regular with no problems at all.
To each their own
I drive 2k miles a month and the savings do add up

You have proved nothing. It's not hype, it's physics. Lots of info here.

It's a good thing your knock sensor didn't fail during that time.
Warning: The VQ37VHR has a higher CR than the VQ35HR.

It's not about fuel economy.

My 400+ hp Stealth twin-turbo (for which I have full datalogging capability) is more prone to knock under normal driving conditions than it is at the track.


Your posts reflect little understanding of the concepts involved, so before others blindly follow your lead, I feel compelled to offer the following for consideration:
Using fuel with an octane rating higher than necessary for a given compression ratio wastes money.
Using fuel with an octane rating lower than necessary for a given compression ratio sacrifices power and risks engine damage.

telcoman

Yes they have
I do respect your opinions. I just don't agree with many of them

No! Just making a point that using regular will not harm my G
Verified with Infiniti service
New vehicles are not delivered to a customer with a full tank of premium

Huh! Design intent?
Don't know what you mean?

You and I purchased our vehicles for different reasons.

I enjoy reading the posts and have even learned a few things like not using cruise control.as it reduces MPG

I purchased my both my Infiniti's for:

1- 6 Speed manual

2- RWD

3- Comfort and features on long drives

HP was never a factor in my decision

$2 per gallon in 2009??? in NJ???
I was paying ~$4 at the time I believe.

The owners manual is clear, premium, regular in an emergency.

You obviously feather the gas, because you can't get that mileage driving hard. feathering the gas will alleviate knock with regular. Can't drive the car hard with regular, it will knock, whether you know it or not.

Infiniti service vs the owners manual? Owners manual wins every time.

kanariya

the average seems like on the low side.
right now manhattan is $4.5 for 93 on average.

I have yet to see ECU timing maps for the G37 but would generally expect advance to be high at low load and low at high load, which could lead to knock in both scenarios when fuel with insufficient octane is used.
Datalogging would confirm when the ECU is retarding timing due to knock count. I am new to this platform but am very familiar with how this works in my Stealth and suspect the G37 employs a more sophisticated version of what's described here. At any rate, telcoman has demonstrated that his ECU with input from his properly functioning knock sensor can retard timing enough to prevent significant damage to his engine. I prefer to avoid knock and allow the engine to operate as intended.

That chart is for regular unleaded as indicated by the Y-axis label. Local prices for all grades are here. Adjust accordingly.
