#31 of 392 Re: 1500 mile road trip [mike048] by esfoad Aug 03, 2005 (8:35 am)
Replying to: mike048 (Aug 02, 2005 3:27 pm) I'm really not doing anything special. It's been pretty consistent since new. We did a 1500 mile trip just as I reached 2000 miles and the numbers were actually better though my speeds were a bit slower because of traffic, probably more like 70-75. I feed her a diet of premium from the local Delta gas station (consistently among the lowest prices in the area). I'm not extremely hard on the car but I'm no slouch either. You might have it checked to make sure all is well.
#32 of 392 6 MT Coupe by g35_ron Aug 04, 2005 (4:34 am)
I drove my 6 MT Coupe from Boston to Texas and got 24.9 mpg. I then drove from Dallas to Austin and back and got 25.9 mpg. Highway speeds for both of these are in the 80 range. My typical driving (kinda aggressive) around town gets me 21-22 mpg.
#33 of 392 5at Sedan by quasiactuary Aug 04, 2005 (5:09 am)
In mixed city/highway driving (with tons of traffic thrown in) I always get right at 20 mpg. I once managed to drive a little slower for a full tank and got more like 23 mpg but it wasn't nearly as much fun
#34 of 392 First fillup by sd_diver Aug 04, 2005 (6:27 pm)
With 193 miles on the odo (198 overall), I bought gas for my 05 g35 sedan (5AT) for the first time today. 11.3 gallons, giving me 17 mpg. I know it will improve, plus I am not sure how topped of it was when I got it from the dealer. New experience buying premium (91 octane) for $2.899 (San Diego). Ouch!
#35 of 392 what octance gas are u all using by yassy Aug 04, 2005 (6:32 pm)
to get at 20+miles a gallon? i suspect many of you use the 87 octane right?
#36 of 392 MPG and Fuel Type by mkrzyzek Aug 05, 2005 (2:23 pm)
I have a 2005 G35x with 3k miles, and I am averaging 17-19mpg. My 1998 Maxima was averaging 20-24, so I'm ok with the G35x. Most of my mileage is highway driving, but I suspect I don't drive the car the way a normal person would (ha).   Regarding gas type, I thought the owners manual recommends premium fuel, as that is what I have been using. Where does it say you can use regular? Replies to this message: neptungrll (Aug 17, 2005 8:35 am) mnrep2 (Aug 17, 2005 1:30 pm) klpeel (Aug 18, 2005 5:08 am)

Replying to: mkrzyzek (Aug 05, 2005 2:23 pm) I use premium, 93 octane ALL the time. I just have never questioned it. I get 20-22 mpg of mixed driving. I belong to COSTCO. Their gas is consistency a lot lower priced than other stations in the area. Last fill up I paid $2.35 a gallon for premium. The car seems to love it. I can get over 400 miles from a tank at times.   Patty

Replying to: mkrzyzek (Aug 05, 2005 2:23 pm) The 05 G35x manual clearly states that 87 octane is the recommended fuel type. You can use a higher octane for getting slightly better performance. This is only for the G35x sedan not the coupe. Replies to this message: klpeel (Aug 18, 2005 5:08 am)

Replying to: mnrep2 (Aug 17, 2005 1:30 pm) I'll double check my manual, but I just read it two weeks ago having recently bought an 05 G35x, and I remember it recommending (but not absolutely requiring) premium of at least 91 octane. In the Washington DC area, gas stations have 87, 89 and 93, which means I have been using 93.
