If you can't get past the teens...maybe you should let your car warm up for 10-15 minutes before driving. Its better for the car that way anyway

Actually, it's worse for the car to sit for 20 minutes ice-cold and idling than it is to be driven conservatively. Conservative driving when cold will warm the engine faster and lead to less wear overall. Been at this winter driving for some time now

I don't recall saying 20 minutes.

I said 10-15... And if letting your car warm up for a few minutes before driving it is so bad for the car..why are you not supposed to drive it after first turning it on in the cold weather?!! Belts squeak when the car is cold....

Not quite sure how having your car sitting while running for 15 minutes is going to improve your gas mileage.

Frost how the hell do you get 25mpg in traffic

OP how the hell do you get 30mpg period, lemme guess cruise control, all highway, flat land the whole way.

Bone stock I saw a hair over 30 MPG on a trip to southern VA. Pretty pleased at the highway economy of this car.

They are not supposed to...

Berk is one of the brands that most people have reported no issues..so...

Fast Intentions have a design which should prevent it as well, so far, I've not heard of anyone tripping the light.

I have Crawford HFC's on my G35C, I have had no issues. And people I know that run the them have had no problems aswell.

Red370 · 12-27-2009, 02:21 PM

I have a SES, but i'm attributing it to an air leak before the O2 sensor because I didnt use the proper gaskets, I plan on getting the issue fixed when my exhaust comes in.

Technology now makes it so you dont have to wait for the car to warm up like you used to. Now it warms up faster if you drive it.

Exactly. The idea of driving right away is that the engine warms up more quickly if you're driving between 1-3k RPM than if you let it sit at 750rpm.
