#70 of 123 Re: GAS MILEAGE [steven48] by busman01 Jul 20, 2008 (11:16 am)
Replying to: steven48 (Jul 20, 2008 7:45 am) Here in metro Atlanta/North Georgia, I use Racetrac premium (93 octane). While not a "major" brand, it is offered all over our area, and it gets the job done. My retailer told me as long as I use a premium w/detergents, everything will be fine.   When traveling, I usually look for Exxon/Mobil.   Don't know much about the tires. I am not at that point yet. However, I probably will look toward Michelins when that time comes.
#71 of 123 MORE TORQUE... by steven48 Jul 21, 2008 (4:42 pm)
I wish my G37S had a little less horsepower and more torque. I would probably get better gas mileage. More torque would be nicer "off the line". I have to get to 4000rpm before a nice kick, I can appreciate it's a luxury brand, but more torque!!! The horsepower 315 would be fine, that's still very fast, and increase the torque to 300 foot lbs. up from 270. Just a thought, thanks. -Steven Replies to this message: dat2 (Aug 01, 2009 2:04 am)

Replying to: steven48 (Jul 20, 2008 7:47 am) I've used Pirelli PZero Nero A/S's as well as summer's on my BMW (530SP). Also Dunlop SP Sport2000 A/S's. I have found the Pirelli's to provide a good balance of grip in all conditions with decent wear/noise characteristics - having switched to the A/S's to squeeze some additional mileage out of a set of tires. Believe there is a price/performance ratio to be considered, so look into doing some research on Tire Rack and using that info to negotiate with your local performance wheel/tire retailer. My guys in Atlanta are superb.   BTW, totally agree that Michelin builds a superb tire, but will cost you more. Only you can determine if they provide the value & performance you need. Again, Tire Rack can provide excellent insight.

Replying to: qaiss71 (Jul 20, 2008 12:45 am) Same here, Apple disabled the 12V/Firewire old way of charging starting with the 3G Iphone. Now it will only charge with 5V USB power. I contacted my dealer about some kind of a solution and waiting to hear back from them. In the mean time there is an adapter that Kensington makes with USB charging and Dock pass though that according to the apple forums will do the job.   http://www.buy.com/prod/kensington-4-in-1-car-charger-for-ipod/q/loc/111/2028077- - 54.html

I have a G37S, and searched exhaustively for all-season tire options. Unfortunately, there are very few, and none in the exact OE sizes for the 19 in wheels of the S.   I ended up going with Michelin Pilot Sport A/S, 245/40-19 front, and 255/40-19 rear. They are each about +1 size over the OE tires, but fit just fine (10 mm is about 1/3 of an inch more tread width). I have used the Michelin's on several cars in the past, I think it is an outstanding tire. The dry weather performance sacrifices very little to pure "summer only" tires, you will not notice a difference unless you autocross the car. They have a big advantage of not only allowing driving in light snow and slush, but superb rain/wet weather performance (which the OE Bridgestone's are not good in).   Good luck!
#77 of 123 All season tires & Ride by jakk100 Aug 10, 2008 (11:10 am)
I would not have bought a G37S if it were my only car to use for winter driving. If you want all season driving consider a model with AWD. The G37 is engineered to be a sports car not a winter driver. When the roads ice up here in WA state, I’ll leave the G37 in the garage and drive the AWD vehicle. On another note: I have owned the G37S with auto trans and all options less the tech package for about six months. The only complaints are: annoying rattles that come and go-like the vanity mirrors and the sunglass box, the tranny shifts into high gear at very low speeds, and the display does not display what gear the tranny is in when shifted to manual shift. The car wants and is engineered to be driven fast and exceeds my expectations when pushing the limits. The Sport model has a very firm ride, as it should be, don’t purchase it if you want a cushy ride. Replies to this message: ingvar (Aug 11, 2008 11:11 am)

#79 of 123 Valve Train Noise by busman01 Sep 01, 2008 (5:09 am)
I noticed an unusual noise coming from the engine several weeks ago. I took the car to my retailor who researched the problem and found the 3.7 engine has a different technology from other Infiniti engines besides the obvious.   There is variable valve timing for intake and exhaust valves. The exhaust valves are adjusted by an electric motor. The intake valves are adjusted internally from oil pressure.   If you cycle the key(turn it off and restart), the noise goes away for a few seconds. then the engine goes back to its original state and somehow does not transmit the excessive noise.   The fix is something called ESTER oil. It comes as the OEM oil from Japan. This oil accommodates the intake valve lub specs. Internally, no one told Infiniti to use ONLY this oil for oil changes in the 3.7 engine.   I was assured by the territory (factory) rep no harm has been done to my engine, and my retailer has learned something as well.
