i dont gett itt. how is it that you drive your car on 87 octane? hasnt that been known to retard timing thus lowering gas mileage and confusing the computer? if all that i have said is bs.. then i will start putting in 87 octane lol

Excellent question nismodan69

Since your area is flat and if you are not racing your G then there is no reason for you to spend the extra money for premium. Try regular & see how it runs.I did and I'm satisfied

Telcoman

Telcoman has a G35, they run fine on either prem or regular gas. DO NOT run regular in a G37, you will void your warranty.

Hit 62k on the '03 G35 a couple weeks ago. Its going up quickly.

Both my 240s are slow moving:
'93 Coupe - 192k
'93 Vert - 116k

LOL, none yet....ok maybe a few. I'm trying to break her in! Fastest car I've ever owned by far!

I put a couple of 1/4 miles on my Camaro when I test drove it. Couldn't help myself. It was the first V8 I had had since my '76 Camaro. Broke it in the right way after that.

Nope not true!

After winding up with 171796 trouble free miles on my previous 06 G35 and trading it in on 31 Aug 2012, I just reached my 6th milestone today with my 2012 G37S. It's never seen a drop of premium and runs like new. Techs at the dealer confirm regular 87 is fine.

False!

My 2012 G37S purchased brand new was delivered with a full tank of regular 87 octane and I've never used anything else.

171796 miles on my previous 06 G35 and now at 82150 miles on my 2012 G37S that has never seen a drop of premium.

A comparison of the computer MPG readout and actual math calculations is below






Starting from the left four tankfuls on a roadtrip from NJ to Florida in December 2016
Two fillups from local driving in Florida, and four fill-ups on the return from Florida to New Jersey

A total of ten fill-ups starting from left to right.
I should mention that on the way down to Florida I did not use I95 which is the shortest route. Instead for the first time I started out going west on I78 to I81 in Harrisburg, PA then I81 south to I77 South to I26 picking up I95 in South Carolina. I wanted to stop by Fort Jackson SC where i had taken my basic training in the US Army over 50 years ago. They no longer allow visitors to military installations.
In any case this route is 100 miles longer than using I95.

Starting with a full tank from NJ
Fill-up #1 in Va I81 at a Pilot truck stop @$1.99 gal 340 miles traveled since the fill-up in NJ and took 15.824 gallons for a 24.49 MPG
Fill-up #2 at a Pilot truck stop in St Matthews,SC @$1.95 gal. 424 miles traveled and took 15.824 for 26.79 MPG
Fill-up #3 at a Pilot truck stop in St. Mary, Ga @$2.07 gal. Problem with the gas pump here as it shut off prematurely at 5.772 with 229 miles =39.67MPG. Tank was not full but vehicle computer read 24.9 MPG
Fill-up #4 at arrival in Florida at a Marathon @$2.24 gal. 326 miles and took 16.229 gallons for a 20.08 MPG which was also inaccurate. The computer read 26.5 MPG
Fill-up #5 local driving in Florida at a local Cumberland Farms @$2.24 gal. 228 miles and took 14.339 gallons for a 15.90 MPG
Fill-up #6 local driving short trips in Florida at the same Cumberland Farms station @$2.24 gallon. 228 miles and took 13.483 gallons for a 15.42 MPG and about to start the return to NJ
Fill-up #7 at a Pilot truck stop on I95 in St. Mary, Ga. @$2.19 gallon. 331 miles and took 13.643 gallons for a 24.26 MPG
Fill-up #8 at a I95 Loves Truck stop in Dillon,SC @$2.05 gallon. 304 miles and took 12.385 gallons for a 24.54 MPG
Fill-up #9 at a Loves Truck stop in Ruther Glen, VA. @$2.09 gallon. 298 miles and took 12.387.gallons for a 24.05 MPG
Fill-up #10 at my local WaWa station home in NJ @$2.39 gallon. 292 miles and took 11.254 gallons for a 25.94 MPG

Overall the entire round trip was 2540 miles and used a total of 101.377 gallons of regular 87 octane gasoline for a overall 25.05 MPG
