Replying to: yjbeach (Jun 12, 2008 5:15 am) 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. |

Replying to: sjaieve (Jun 13, 2008 6:38 am) 1 - Audi A3 2.0T 6-Speed -- By far the most enjoyable the three to drive, and has the most rear seat space and the most utility as well given the mini-station wagon configuration. 2 - Acura TSX 6-Speed -- Fun to drive, lots of goodies (that I don't necessarily care about), and reasonable space in the back seat. 3 - Lexus IS250 RWD 6-Speed -- Extremely boring to drive with no "feel" of what's going on with the mechanicals or down on the road. This car also suffers from an anemic engine (at least until you wind it up even higher than the Acura's already high strung mill) and a back seat that is all but laughable. In every respect, this car is a very distant third of the three. Best Regards, Shipo |

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

Replying to: darrinzramz (Jun 13, 2008 8:32 am) 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 |

Replying to: shipo (Jun 13, 2008 8:57 am) Fuel guage is what it is...I think it was the old BMW where they made the guage for the last 1/4 tank of gas almost 3/4 of the guage. It's rare that it matters how full the tank is when it shows full...but it really does matter when you're down to 1/8 a tank. High performance plugs and "high efficiency" air cleaners do almost nothing in a modern engine. Actually, most all additives also do nothing, in fact most car makers recommend against using ANY additives in the car. If you aren't driving aggressively, then about the only thing you can do that will really improve mileage is to turn off the A/C. |

Replying to: ghstudio (Jun 13, 2008 11:10 am) I get consistent 22 mpg tank to tank. Why you would use low octane on a higher performance engine is foreign to me. My car weighs 3,700 lbs and still gets acceptable gas mileage on standard A/S tires because each month I regulate tire pressure and rotate the tires each 5K miles. Tires last longer, wear even and get the best efficiency as a result. It doesn't take much to get the specified MPG rating for your car if you are aware of the small details. Regards, OW |
