On my last trip to vegas, I got about 23mpg, but that was also at an average speed of 90mph, and for those who have driven the i-15 from CA to Vegas no that there is a steady climb there, and a very short but very steep climb back. So I was happy with the 23mpg that I got. On my normal day to day drive I get about 14-18mpg depending on how heavy my foot is that week.

 

I've been getting 21-22 around town, 27 highway driving w/AC and a relatively light foot. Mileage has been going up since about 10K miles. Not using synthetic oil yet.

 

I get 20-22 and I drive 35 miles each way freeway to work.

 

After 2 fill ups my average is 19.238. A fair amount of highway but a fair amount of having fun with the new toy too! Based on my previous habits with my S2000 I don't expect this to go up...

I've got a 35 or so mile commute as well either all freeway or 70/30 hwy/city depending on route.

One thing I have noticed thus far, the '05 has a 20 gallon tank correct? My first fill up I drove all the way home from work with the gas light on, only filled up 17.6 gallons. Today when I filled up it had just gone on and I put in just over 17 gallons. That's quite a buffer if the tank really is 20 gallons!! Anyone else experience this?

 

yea the gas light is very conservative. It tells when you have about 3-4 gallons left in the tank.

First tank I got: 21 MPG
Second tank: 20.8 MPG

 

Yup, if I fill up right after my light comes on, I constantly get about 16.5 - 16.8 gallons in, so I agree, appears to come on w/ just over 3 gallons left in the tank.

I drove to vegas and back on friday and I got around 29. It was so rad!! I think the more miles I get on my car the better it is getting. I'm still under 7k but still, its a whole lot better than the 20-21 I was getting not too long ago.

 

Do you guys think a CAI or drop-in K&N filter can increase MPG? How about Red Line's Water Wetter coolant additive to decrease temp? I've heard of this thing called Fuel Power too, anyone tried it? Am I nuts?

 

Mine does 30mpg with hiway only driving.

 

are you talkin about the Top Fuel Power Neo?

 

Currently with 5300 miles on it....

I'm getting 18 in the city and between 25-28 on the highway.
highest reading was 28.6 on a 200 mile highway trip.

 

No, it's this: http://lubecontrol.com/ Everyone raves about them. It's $26 a gallon and I guess it works like Red Line, cleaning and optimizating fuel burning. I'm interested if anyone got good results?

 

20 mpg average...15 mpg when driving hard

 

15-16 mpg, 98% city/backroads/stoplight driving, 3000 miles on the car.

 

12-14 mpg... about 50/50 highway/city

n.b. Have a GReddy Twin Turbo set-up.....
