I bought my car on Tuesday from Orlando and driving home (about 2 hours) the mileage shown was about 36-38 mpg the whole time????

Depends if it's mostly all highway mileage or not

brickerenator

very good

2k7darkknight

Yeah it was pretty much all highway; about 60mph the whole way. I just thought that was unusual for a SC, is it not?

brickerenator

no
some people report numbers as high as 42mpg

anomolous got 59mpg did he not?

No, as long as you were keeping a steddy speed and not WOT thast sounds good.

36-38 is where you should be on the highway.

I hit 42mpg on several occasions before, but if you get the least little bit of traffic it will kill that pretty quick.

I can't remember anyone getting higher than 45-47mpg but it's probably possible. But at that point, you're going out of your way for the mileage, so IMO that's not the "true" mileage the car's capable of.

When I've hit 42mpg I've never been making a huge effort to squeeze that kind of mileage out of it, just driving like I normally would.

he had tuned it and modded it

Wow that's pretty crazy... in that case I'm assuming my city average of 26-29mpg is normal also...

Why would our cars be rated at 20/29 then???

Yep that sounds about right.

ALL of my cars have gotten higher than the EPA rating. I think it has to do with what they consider to be an average city/highway cycle.

my 2.2 gets 37-38 going 70mph

I averaged 31.5 mpg in an 08 SS/TC over ~850 mile trip pretty much all crusing between 65-75, average speed was 62 mph.

That sounds like pre-break in mileage.
