Have three close friends with Audi's. An A8 3.0TDi, (with a gazillion toys fitted at the factory), an A3 2.0 TDi and an RS4 Avant. First two are 2 and 3 years old respectively. The A3 has 78k miles on it without any glitches, (he's trading it next Jan for an Audi TT TDi 'cos he heading for second childhood. The A8 has around 60k miles and has only suffered one glitch - two weeks ago the Audi satnav decided to stop working for 10 minutes whilst driving around the Paris Peripherique, (great place to lose satnav), but came back of its own accord. The RS4 is only 6 months old and no hiccups but same friend also has a Ferrari F355 which seems to go wrong on just about every trip...............to the extent that he's gonna sell it as he thinks the RS4 is a far better-built car, damn near as fast, far more useable and it doesn't attract the wrong sort of attention from the boy-racers or constabulary, (we have a couple of Subaru Imprezza WRX police cars locally which do send out a certain Clint Eatwood-esque message. "Ya feelin' lucky, punk?" or perhaps, "Make my day". Very entertaining though.
 
Other folk I know who've had Audi's swear by them - not at them. You've either got a or folks who don't know what they're doing with the diagnostics etc.
 
On the other hand I have a neighbour with a newish Mercedes C-class and he's either having an affaire with the Receptionist at the local Mercedes dealer or the car really is a dog. Just to balance that a near neighbour has one of the old, squarish, M-B S500's...........the one that just needs a big gun on the roof to complete the Main Battle Tank image, (it's even painted dark green metallic), and with 200k miles up it just keeps going but does have a drinking problem which is starting to hurt with gasoline here, (UK), at the equiv of $9+ per US Gallon.
 
As with all things electro-mechanical there are great examples and not-so-good ones. Isn't that part of the fun ?
 
Apologies for the long-winded response. Blame old age. Mine.

Hi need some answers if possible,I have a G35 sedan 2004,I've been using 87 octane in my car w/no problems at all.Seems to me when gas gauge reads full,I watch the gas gauge over the course of the week,and I notice it stays up near-full for the 1st 85-100 miles I put on the car,then all of the sudden the gas gauge seems to go down quite quickly from there.I'm medium on the gas on occasion I will get on it medium to slightly hard,it seems I'm only getting 15.6mi/gal,does that seem a bit much or not!!!????.Anyways I've change the plugs to a performance plug also I installed a K&N filter,there is no gas leaks what so ever!!!,any suggestions would be greatly appreciated,I also do use my cruise contol also,do mostly city driving though, not alot of stop and go,thanks Darrin Lynch

A few points:
 
1) Over the decades I've had dozens of cars that were from Asia, North America and Europe, and every one of them has exhibited the same gas gauge characteristics as your car (i.e. the needle is fairly stable for say 100 miles following a fill-up, and then it drops like a rock). This is totally normal as the level of fuel when "full" is typically above the top measurement range of the gauge sensor.
 
2) IIRC, Infiniti recommends "Premium" gasoline for your 2004 G35 engine (an engine well known for its poor fuel economy by the way), you should check your Owners Manual to be sure. Assuming that's the case, by running regular you are forcing the engine management system to retard the ignition timing to keep the engine from blowing itself to bits because of the low grade fuel you're feeding it. In turn, retarded ignition timing will further reduce the already marginal fuel economy of your engine.
 
3) Given how modern engine management systems work, it is physically impossible for a K&N filter to improve fuel economy. In fact, there is a fair amount of empirical evidence that suggests this type of a filter can reduce your economy.
 
4) Based upon the reports of other owners of your car, 15.6 mpg is not too far out of line for "mostly city driving".
 
Sorry I couldn't be more helpful.
 
Best Regards,
Shipo
