Fuel Economy

[Hershey]

The car got 40.77 m.p.g. calculated , while the ECO read 40.6 . Going to leave the ECO at 94 . That way it's actually doing better than the ECO overall m.p.g. display . It took 8.621 gallons of SUNOCO 87 w/ 10% ethanol at 1 click . The trip A was 351.5 miles . New Continental Pro Contact Eco Plus tires set at 35 p.s.i. . Rides , handles much better and a bit quieter with these tires . Gas mileage seems to be the same as witht the Potenza RE 92 .

Filled up Friday the 13th! Pleased that I was able to break 50 MPG the first time with ethanol gas. I had a 300 + mile trip on this tank!

Gas Tank mile increments (ethanol gas used):
1st Bar drop (8/8) > 120 mi (120)
2nd Bar drop (7/8) > 60 mi (180)
3rd Bar drop (3/4) > 60 mi (240)
4th Bar drop (5/8) > 60 mi (300)
5th Bar drop (1/2) > 65 mi (365)
6th Bar drop (3/8) > 50 mi (415)
7th Bar drop (1/4) > 70 mi (485)
8th Bar drop (1/8) > 0 mi (485)

Tank total : 485 miles
Fuel used: 9.195 gallons
MPG: 52.746

Cheers!

got 51.98mpg last tank...i kinda killed some of it on my last commute home, i kinda had to rush to catch a store before it closed & i got out of work late...but this proves the car prefers the stock exhaust for best fuel economy

Compared to what? I can pretty much guarantee there are exhausts out there that will get better gas mileage. And then there is always Unobtanium.

Very nice, malibuguy!

I took a 300+ trip on that gas fill (52.746 MPG) and drove 45-50 MPH on rural highways and some open interstates. I was suprised that I was able to get over 50 MPG on the tank using ethanol now. With all my other + 50's I was using non-ethanol. I changed my driving technique a bit to compensate for the loss of energy using ethanol gas. I also use a stabilizer for the ethanol...1/2 to 1 oz. You get around 1-3 MPG less using ethanol blend than RBOB gas. On this present tank I'm taking another shorter trip this week. So far my first 'bar' I got 120 mi and the second was 70 mi! Better than last fill-up. We will see if I can get two in a row...

Cheers!

compared to the 49 & 50mpg i was getting in better conditions with my custom full exhaust...when your barely using any throttle & staying below 2700rpm...your not pushing that much airflow

i thought i was going to pick up mainly from running a 100cell race cat versus the 2 400cell cats our cars get...i guess i was wrong

that being said...the car was definetly faster on the top end the few times i did floor it with my custom exhaust...but i didn't buy this car to race it

Ah, that is not surprising then. Most exhausts around are meant for the high end, just like most other go fast goodies. Finding parts that will help the low end for a car like ours isn't easy.

i was thinking about switching out my main muffler for a DynoMax VT valved muffler...but fuck it, i'm just going to keep the car stock

Also same here. I routinely can drive into Inkom and get 70+ mpg, it's 1,000' below. It's that long pull back up to get home that gets less then 20 mpg. Still, when I get home, it's in the 40's.

Owned the car for less than two weeks, I had a small opportunity to test out nearly all Highway mpg, I tried to stay below 2500rpm and managed

119.7miles at 2.366gallons = 50.59mpg

odds are everything in the market is going to hurt the bottom end. I think there was an intake that actually added to the bottom end, but that's it. Odds are everything else is going to hurt gas mileage without thousands of hours of research and development.

I just got a new best too, 43.6. I think the summer gas blend is helping.

I started out just wanting to average 40 MPG but when I see what some others are getting I want MORE. It will take a while to get my lifetime average up to 40.

Just got back from a long trip, mountainous terrain, not many passed us. 500km on 27l of fuel, 3 tanks. I'm happy with the mileage, thanks.

Guess I should post so I can see my avg now. didnt look at gassavers.org when I put the fil up in,lol

[malibuguy]
