What are your rpm's at 70mph?

This question is for the stock G owners.
Just curious what you're rpm's are at 70mph?
I'm around 25-2600. I have aero and not sure if that makes a differance.

might want to mention your tranmission type since most manuals will be lower than autos at the same speed. they typically idle 100-200 rpms lower.

I have a bone stock 03 AT sedan and at 70 mph my RPM's are 2500 with a mild fluctuation of 50 RPM in either direction with Cruise Control set.

The only reason I can give you such a precise number is that I commute 60 miles each way to work and gas mileage, etc is VERY important to me and I find 70 mph to be the best compromise of fuel consumption and the amount of time it takes me to get home. ;-)

I'd rather do 80, but the almost 500 RPM drop to 70 has upped my gas mileage quite a bit!

AgentAero04,

Just to add to this, I have been keeping track and checking numbers and with a slight variations, I can say that I am getting about 24-25 mpg on average. This was closer to 20mpg when I went 80 mph regularly!!

Obviously the advertised numbers from Infinity are BS, but 24 is better than I thought I was getting!!
