[1meanz]

what kind of mpg are you guys getting with your large port 3x00s? im getting right at 33 mpg with my hybrid right now on stock chip! just thought id share. i was getting like 18 and it jumped to 33 when i fixed my vaccume leak lol.

BLAH, i get 19 on my stock 3100 with 3.33 gearing right now... I'm going back to 3.06 to see if it raises it up. I was getting 19 before on my cammed hybrid too.

I get around 16mpg (mainly city) but I have some reasons behind that (see sig)

1meanz: what car/engine do you have?

I get around 22-23 in town with a tiny bit of highway but that's with me going WOT all the time hehehe.

Jon: Hehehe damn, well I guess that means you could throw in another hybrid in your DD and still get good mileage haha. I guess your cam isn't that radical (well the old one)

[1meanz]

i have a 94z with a 3.1 block, bored .030 over, a cam, not sure which one it was put in befor i got the car, ported 3400 heads, and ported 3400 lim/uim (large port) 95 3100 injectors/fpr and stock tune

That old cam SUCKED!!! it just sounded good... LOL But yeah I think my mileage is directly related to my gearing. Can't wait to see how pinky responds to 3.42 gearing...

[IsaacHayes]

Yeah that's the only thing I like about the stock gearing is the good mileage. Now that my engine is modified a bit and I have more power the gearing doesn't suck so bad. 2nd gear isn't so dead when you get stuck in it anymore.

Can't wait to see how much better your new cam is.

[1meanz]

what kinda gearing is on my stock z24 5 speed trans? j/w because i loose EVERYTHING in 4th, 2nds good, 3rd looses alot after about 3500 and 4... its ok but other then that it sucks lol

your gearing and that heavy thing called you right foot

[3400-95-Modified]

I got 20.2mpg this last tank and that was with a light foot... No need to stomp it anymore because its a stock motor, it doesn't do anything. LOL

[geldartb]

now your snow tires will survive and still have middles left when winters over.

haha, i burnt through the set i put on at the begining of this year with the hybrid... I just swapped them over for a new front set... we'll see how long these last LOL

[bszopi]

I just pulled ~22mpg on a basically stock 3400 (62mm TB), over 4k on the oil, over 20k on the plugs, letting it warm up 5-10 min every morning, and sitting in traffic to and from work. I drive ~18 miles each way and it usually takes me around 30-45 min each way. There are several other things wrong with it that I know are affecting mileage, but I just don't have the time to troubleshoot and fix them right now.

[1meanz]

thats not bad^^ the only thing i know that is wrong with my car right now is #1 i have a hundred different vacuum problems right now. and my oil pressure is reading like.... 15pis. opsu is on its way and ima mess with the vacuum in a few days. and we will see how it goes from then on... im getting practicly no vaccume on anything thats not connected directly to the plenum. when befor it was fine LOL but its all good. im holding a stedy 18.5 or so everywhere im getting vacuum.

I get about 28 on the highway with both my 3100 engines- in a '94 Corsica and an '01 Lumina.

More like 22 around town.
