I just bought a 94 ls, and I feel like I am burning too much fuel. I eatimate that I am getting between 15-18 miles per gallon, is this right?? Can someone email me and let me know?

 

[CakeDaddy]

I say get a tune-up, oil change, fuel filter and air filter change. You should notice a difference. I get 22mpg. Oh, and use the high end gasoline 92,93, or higher octane

Depends on the use of that gas pedal, everyone is different. Might be no problem at all.

i get around 13-14mpg.... id LOVE to have your gas milage. honestly id expect that kinda milage from a car that has as many miles as mine does.

Check you EGR valve and tube, at 135K mine was completely clogged shut. That will effect you gas milage. Also your number sound right for all city driving but not for the freeway. You should be getting over 20 on the freeway.

 

[legend4life]

what is the EGR valve and tube and how do u clean it?

- 18mpg from 79K (when I bought the car) to 90K
- 20mpg after timing belt, water pump, drive belts changed
- 22mpg after oil change w/NSX Oil Filter

Is that mostly back roads? Do you have an automatic? How fast are you driving?

why do u think an oil filter would help gas mileage???

18-20 mpg at 94k without the 90k checkup, standard

Just put some fuel intake cleaner in. Have driven 100 miles on a quarter tank with a heavier foot than usual (22 mpg). Hope to get more after I change the oil, replace the spark plugs, replace the timing belt, put in a new exhaust, and all that good stuff.

I recently blew out my exhaust while doing the post incredible peel out ever. Reved to 6000 rpms and dropped the clutch. Had to back off for fear that I would burn the tires straight through, went straight through second gear. I was wondering if anyone could give me an idea on a good exhaust system to buy for my 89 Legend L (the old exhaust was **** anyways, the car used to be owned by an old man, and now I have an excuse to give my dad so that I can replace it). Thanks for all the help.

Any other ideas for modifying performance and looks would be much appreciated. I will probably put about 2k into the car by the end of the summer.

acpac-jet- As you probabally already know, ANYTHING but OEM will be an improvement. The OEM muffler is just huge and quiets the motor just a little too much. I didn't want to drop $300 on a new set up when my old muffler rusted off, so for around $100 i got a universal single-in, dual-out with 2.5" chrome tips welded on. With this muffler 1/3 the size of the OEM, the tone gives a very nice hum under 3000 rpms (enough to set off car alarms in parking structures) and a nice VRROOMM when starting. Maybe (!) some power gains in the mid RPMs. Also, looks much better than stock.

Anyway, just giving you an alternative in case you don't want to spend a lot more money on an OEM muffler or an after-market "performance" muffler.

Mere coincidence. I'm just posting what I noticed. It could've been coincidence that 4000 miles after my timing belt, the timing belt and all the remaining drive belts were not as tight, or whatever the case may be.

Please correct me if I am wrong, most universal mufflers are rated only up to 150 Horsepower, after that, it becomes obsessively loud, simply because it can't handle that much power coming out of it.

I get great mileage....if all hiway, the highest I have gotten was 26.1 (use Texaco hi-test, or shell..other brands I get significantly less) with moderate city driving last tank was 23.4....these numbers went up since changing plugs, just replaced with same stock platinums....was getting around 22, so I am sure plugs helped....the old ones had about 50k miles on them, so were definitely ready....I am easy on acceleration, so my style is conducive to high mileage.....I use Valvoline 5-30 regular dinojuice and change at 3000k miles

 

[legendHI]

asianlegend- i'm not sure what you mean by, "obessively loud," but its only moderatly loud under 3000 rpms (still softer than any after-market exausts) and quiet as a bee after 3k. is there any risk of me blowing the thing off or damaging it?

i'm pretty sure this muffler, whether its actually a "universal" or some cheap performance knock-off, is doing quite fine with my G1's 161 horses. i really like the tone, to be truthful.

The G1 has 161 hp? I thought it had more. You got the 2.5 or the 2.7? ah, that's ok, I don't think I would know anyhow, since I don't even own a G1. But, just curious, what are the HP vs. Torque specs of the G1.

As for the muffler dying or something, I don't believe so, it's just louder, since the material used for the low tone and such are in there for a reason, but too much power may lessen the effect of softening the tone.

G1 specs

(data from legend.org)
-if anything, its best to stay with a coupe or an 89-90 sedan. i would suppose ten horsepower is more than nominal. a 161 hp is just enough to have fun with (i suppose for its weight).

does anyone get better performance and/or milage with a higher grade of gas. I use 89 octane, but I am wondering if it would be to my advantage to swith to 90 or 91 (or maybe even 92). I did hear that using a gas grade higher than what you car was rated at can actually hurt the car (something about when you start up and stuff), this true?

I can tell you on other cars, since my Legend requires Premium, I only use Premium.

But, when I owned a 96 Teg GS-R Sedan, I could tell a noticeable difference in MPG on an 80-100MPH average speed:

Regular Unleaded [87 Octane]: 22.5MPG
Plus Unleaded [89 Octane]: 24.25 MPG
Super Unleaded [92 Octane]: 25.40 MPG

Keep in mind, the 96 Teg GS-R has VTEC which opens an add'l small valve at 5000 RPMs.

i get around 21 city, 28 highway. it also depends on how i drive, especially since its a manual. i just dont feel like shifting sometimes, and ive gotten as low as 12mpg.
