How many gallons does a gas tank of a '01 3800 Camaro hold? Is it the same gas tank used in the LS1 cars?

I'm trying to figure out what mpg I am getting with this car. I have heard that our gas tanks hold 16.8 gallons. If this is correct, I am getting a little over 300 miles per tank.

300 / 16.8 = 17.8 mpg

That doesn't seem to be very good for my car. I have a 5 speed tran and thought I would get better gas milage.

In an effort to get more miles per tank, I try to shipt around 2500 rpms and keep my crusing speed at 2000 rpms.

What do you 5 speed 3800 guys shift at an cruise at?

 

Not sure about your capacity since mine is different. But I think your calculations are off.

Unless you are driving your car until it runs out of gas (which I doubt you are doing), don't divide by a full tank.

Example: Odometer reads 300 miles...you refill with 10 gallons. Since you refill with 10 gallons, you used 10 gallons. 300/10=30 mpg

Just take the miles you drove on that tank and divide that # by how many gallons you pump in.

 

95 3.4 ..i get between 22-24, anybody else

 

I get about 32.4 mpg I do almost all highway driving..not to bad for my pig v6! 5-speed..I think the tank only holds 15 gallons..Ive ran mine pretty close to empty and the most it ever took was like 14.6 gallons...

 

The older 4th gens like mine have a 15.5 gal tank. Your '00 should have a 16.8.

Oh, with my '94 3.4 auto I never got more than 20 mpg.

 

On my 94 3.4L automatic with 96,000 plus miles, I average 18 - 23 MPG depending on how much city driving I do.
I have a 21 mile one way commute to work, mostly on interstate, so alot of my miles come from that.
The best MPG I have ever gotten was 28. That was on a 12 hour one way trip down the interstate. For the whole trip I was between 27 and 28 MPG.

I consitenty get 26 with my A4, flowmaster, and K&N filter. It comes out around 400 whem i fill it.


As far as shifting goes I average shift at 2800 and keep it reving around 2000.

 

Last time I checked I was getting only 20 mpg. But that is a lot of city driving, and shifting (automatic) between 2500-3000 RPMS.

I've noticed a difference since I put the Lid on, but haven't done the math yet. Do you guys usually notice a difference after the Lid or any intake mod?

 

My best average that I calculated was 28.8.. part city, part highway.

On the last tank of gas, I hit 252miles when the needle got to the 1/2 tank mark (which isn't really half a tank... the way the gauge moves). At any rate, I'm making 30+ highway with my auto and 3.42's.

 

what can i do to get milage...like im gettin 24ish i want better if possible

 

I cut my cat off and run dynomax muffler with a 5 speed i get 30 on the highway and 22 in town. Since i have put on the ram air hood i noticed lower rpms at the same speed where they were higher without the ram air hood. it seems likes the mods have given a litte better gas mileage.

 

As i said with the intake mods i have done the rpms are lower at the same speeds than they used to be. For example before mods: 5th gear at 50mph was 1500 rpms. After mods 5th gear at 57-58 is 1500 rpms. Just what i noticed. If i shift to 5th now before 55 it will bog down to much, it did not do that before.

 

Just got back from all highway driving and averaged 36.5 mpg. 450 miles / 12.2 gallons...ya I was shocked too for cruising mostly at 75mph and about 2k RPMs...it's a 2000 bird with 5 speed manual and i'm running premium gas with HPP3 tuned to high performace, holley power shot filter, lid, and B&B triflow exhaust...and mobil 1 synthetic everywhere

 

I drive 100% city and i get 18-20 mpg, depending on how hard I drive it. Hopefully this will go up with the addition of the FRA mod and Filter, and soon new gear and tranny lube.

 

i get about 23 mpg, that was w/ 75 percent highway driving at 85 mph. not too bad for a 3.4 w/ 180,000 + miles . l8tr,

oh yeah, and i dont' have any cats on my car!
