back on my 93 tune i could manage high 30s. saw the miles to E quite a bit over 400 before lol. now i'm like 20-23 total average on e85 =\

 

Just did a 5 hour drive from NY back to Maryland, average speed between 75 & 80mph. I just put in a new clutch yesterday so I didn't get into boost and here is what I got. It was higher when I pulled into my garage...36.6. When I filled up it said my fuel range was 485 miles.

 

I have seen almost 400 myself once, usually get about 250-300 though with traffic and merging onto 485

 

Around town I see about 27/28 mpg but I live on base and put about 8 miles on it per day at 35mph.

 

my best is 37.5 but i have been averaging about 35.5 now, going to see what a new air filter will do to that.

 

My best was 36 mpg but that was all cruising

 

+36 for cruises and 21 around the city i dont have to drive much but it kills my DIC avg.
The AVG mpg will always drop that low eventually but im still TRIP'n +80 miles on $12.00 of gas thats a overall good avg of +26.6 ($3.99-$4.06 93 oct. so 3 gallons).

 

I am sure this has been discussed before but anyone else noticing their LNF pulling anywhere between .5mpg - 2mpg better aggregated fuel economy in weather > 60 degrees F vs weather<60 degrees? I have been driving the same but I am up to 31+mpg/tank since the weather warmed up in Seattle.

 

I regularly get 30 mpg for my average in my SSSC. The highest I have ever gotten is 38.. that was all highway going 69 mph...

Stay out of the boost, shift at around 3k rpms, easy mpg

 

my highest in my sstc so far has been 28.61mpg... and my lowest has been 24.17mpg

I keep this all recored in a sweet app called "my cars"

 

i though the dash MPG thing was off by like 20%?

ive got 38MPG before coming home from my cabin. doing a pretty steady 60MPH.

currently around town im getting a steady 27-28MPG. im heading up to my cabin this weekend so im going to check it since last summer when i got 38MPG i was bone stock. we will see if GMS1 and a couple bolt ons hurt much lol

I got 34mpg when driving from Alaska to Idaho. Made it to Washington in 3 days starting from North Pole Alaska.

 

oh and was doing around 90mph most of the time I was in Canada.

 

me>everyone in this thread.

Granted I have a 2.2, 93 octane HPtuned and bolted but it gets incredible MPG, I also have 40psi tires. This average was on my 30 minutes commute to work, on the way home its about 60% downhill, not a big incline or anything but yesterday I got lucky and only hit 1 stop sign and one red light, as apposed to the 6 lights I pass on the way:

i forgot my wallet at the house, didnt have gas money, low fuel had been on for like 30 miles, so i seriously babied it! and it was 40mph the whole way through

 

I get about 28 In the city. 35 on the freeway at around 85...I get about 40-42 doing 60

 

someone's tank is on E (extra full)

 

Likely varies from car to car, mine is about 3% happier than it should be but it is consistant.




Nah, that's E for Expen$ive

 

I've yet to see under 35 since I ditched the heaton. Both city and hwy.

 

im going to check mine this weekend,ill keep track of it on the dash and when i fill up at the end of the weekend.

 

Lmao, 2.2l NA and I average around 25-26 mpg total

How the heck can i get my car to do this again? My dic has been reading pretty constant at 27 mpg avg. for the last year.This video was from 3 years ago.Damn! I just noticed the 410 fuel range left after a 49 mile run???

 

39.5mpg from Arizona to Minnesota the whole way.

 

Driving expressway on my 93 tune I get 32-34 average. My average overall is **** since it's quite easy and tempting to get up to high speeds. It's around 26 average though which isn't awful compared to some of the numbers I've seen on here :P

 

Seattle to Boston - 29.3 MPG, avg speed 68 MPH.
