Well, is this pressure the same as when you open the cap with an almost empty tank and you hear the sound like a shhhhhhhhhhh sound coming out? I dont ever hear a leaking sound when the cap is on, but hell i'll give it a whirl, if i change it for 15 bucks and perhaps get a few mpg more

my '96 SC400:
Spring / summer w a/c off: 19 - 20 suburban driving
Winter: 17 - 18 suburban driving...

MPG goes down in the norther part of the country b/c of the switch to "winter blend" fuel about 5% or so and generally gas milage is worse while the car warms up.
Also 1992 -1997 SC400 factory EPA 18/22 mpg City/Highway; 1998 - 2000 factory EPA 19/25 mpg city/highway... why?? vvti & 5-speed trans... enjoy the COLD winter.... At least gas prices are going down: today's lowest by me $2.09 (89 octane)

Every once in a while when I take about a 5 hour mini-road-trip to go visit my mom I will fill up with 91 Octane (not 93), make sure my tires are inflated properly then hit the road; best average so far was 26.7mpg. (I think I got 475 miles before I filled back up, the light wasn't even on yet) 95 SC300, 5-speed.

Around town my mileage is horrendous, 15 maybe 16 at best. All I've really done with this car since I got it was to change all the fluids (except brakes) and change the cap/rotor, she's got 113k on her now, hoping for 113k more!

Thanks again for the replies....I drive my S2000 around town and what not, The bulk of the milage I drive is to and from school/to and from work, which I get right on the highway and right off.....so these figures sound decent to me, considering my 1.6L civic gets only 22-28mpg. . .

The SC400 is your best bet for a DD, as long as you keep from going crazy at every light. But if you consider a swap down the line your milage will also increase. I get 23-25 MPG on my DD 1JZ.

The reason why the gas cap might work is because, if the cap draws in air and air gets into the tank, the gas will evaporate.

hmmm i may just do that gas cap thing. so all you do is get another one and then disconnect your battery for about 10-15 mins? noice

wow, im glad this thread just got interesting. Ill definitely have to give it a shot. I'm actually recording the full mileage im getting off a full tank of gas and I'll do it after the gas cap and post results

So far the fuel meter is at 1/4 gas left and ive gone ~225

actually you can also...Reset the ECU codes by removing the 30amp fuse
(EFI #1) for 10 seconds or more.

sc400, i get 16-17 city and 22-24 hwy, the gas mileage btw the 300 and 400 won't be significant enough to decide which car you want.

As long as you do not beat the crap outta the car, it should be in the 20's.
