*** Looking for info on A4 cars ONLY (prefer 2.73 gear info, but 3.23 is also welcome), and stock/bolt-on cars ONLY (no internal engine work, or big stall TCs). ***

I'm thinking of making my '02 car a 100% straight up daily driver, and selling off my econo-box. But considering I drive 70+ miles per day, gas mileage is a concern. I've owned 4 different LS1 F-bodies, but I have never used one as a regular daily driver, so I've really never tracked MPG very closely.

Here is what I need to know:

- Gear ratio.
- Stock or bolt-ons (please specify which bolt-ons)
- Driving style (easy, aggressive, wild)
- Your best MPG for a tank of gas (please specify city, highway, or mixed)

My current DD has attained a best MPG of 35 with mostly highway driving, or 30-32 with more mixed driving. So I want to see how much I'll lose going to my stock 2.73 A4 LS1.

3.23's city/highway mix i could get around 280 on a good tank. obviously a little more on all highway. when i start playing it drops to like 240-250 fast. think it was about the same before the exaust. never had mine tuned though. think there is room for improvement because the idle isnt perfect.

city/highway mix.....250ish....with my style of driving before the heads, cam and stall, which is...i have to be out in front!!

I have a 99 Z28 Camaro. It has the following:

-Stock 2.73:1 10 Bolt Rear
-Bolt Ons (SLP Air Lid, SLP LMII Exhaust)
-Driving Style: Easy since gas went through the roof, trust me on this one.
-Best MPG for a tank of gas: about 25-26 all highway, flat roads constantly at 65 mph with the windows up and no air conditioning (not the typical scenario). The car typically runs about 16 mpg with 25% highway and 75% city. Keep in mind that I am in a congested area.

I hope my information helps. I usually spend about 20 dollars to drive 100 miles in my Camaro with gas at the current price.

Prior to LTs and ORY I got a best of 27.5 mpg with 3.23s on the highway. That was with two WOT pulls too

When my car used to be pretty much stock (lid and cutout) i have gotten 31MPG on the highway...i used to make a 300 mile round trip every other weekend when i was in school..and i would consistantly get between 28-30..with every once in awhile getting 31..This was with 2.73 gears, and driving it very easy.

1999 Camaro with 186,000 miles
LS1/A4
3.23 rear end
SLP lid and exhaust cutout (I have the cutout open 90% of the time)

I've calculated mileage twice (using miles traveled / gallons used)

27 mpg on one occasion (90% hwy/10% city)
22 mpg on the 2nd time (25% hwy/75% city)

Great info so far guys. Thanks.

But please try to keep it to MPG rather than miles per tank, since some people fill up at 1/4 tank, 1/8 tank, etc. It's just not as consistant for measurement.

Great reply, exactly the sort of info I'm looking for. But I'm a little surprised you only got 25-26 with the conditions you described. I was thinking 28mpg+ with 100% highway and 2.73s would be easy with what you listed.

Now that I think of it, it could have been closer to 28 mpg. That was a one time deal, me and my buddy were coming back from the shore at night and it was cool out, all the roads coming back were flat (Jersey), so I figured I'd play the gas mileage game.

I never got over 21.5 mpg. And that's on the highway. '02 WS6, with a lid and catback only. 3.23 gears. Now have an '02 with a M6 and the best I've gotten with this one is 27mpg on the highway. Don't really expect a lot of mpg from an A4. But then again I've never driven an f-body with 2.73's. Andy

~12 city
~20 highway

but this is with a cam, and high stall.

i drive pretty easy in the city, and keep the rpms under 2k on the highway.

on my last tank i got 200 miles....75% city driving. but this had at least 8 WOT passes....It was the tank i used to get it dyno'd

'00 Formy, A4, 2.73's, 71k miles:

Since I've gotten the car in August, I've tracked the mpg pretty consistantly. I've averaged a best of 23.2mpg, and a worst of 22.1mpg.

I think I've gotten worse tanks than that, but I haven't really tracked my mileage since mid december, so I can't say for sure.

That 22mpg number is pretty consistant though.

NO mods escept a SLP lid, and that didn't affect mileage either way.

I drive very easy, I rarely take it over 70, I normally set the cruise around 65 or so. I drive 65 miles a day, so I feel your pain about mileage. That's why I drive so easy, I get better economy that way.

My driving is mixed, I don't do alot of strictly city, but my commute consists of 12 miles of two lane rural road, 35mph limit with about 6 lights, and 22 miles of highway, limit is 50-65mph, with a few good hills thrown in.

I'm a little dissapointed with the mileage, I was hoping to average 24 with it. I guess I can't complain though, considering what it is, 22 isn't bad. It's much better than my 16mpg 6 cylinder Jeep.

Fast Toys Ram Air claims up to a 10% increase in economy...if that's true, it'll get me up the the 24 that I want. ( I want it anyway though, any economy increase would be icing on the cake) It's not so much for the mileage...I just wish the range were longer, I hate that I can't make it through a five day workweek on one tank.

I'm also switching from my 245/45/17's on aftermarket chrome wheels (were on the car when I bought it) to 225/55/16's on stock alloys. That might help a bit, those 17's look HEAVY.

Hope that helps.

How the hell did you manage that?? Only drive downhill?

Looks like the averages are all over the place, from low 20s to near 30 with mostly highway driving.

I guess I'll just need to spend a few weeks DD'ing the car and see what it does, before I make a decision. I'm 100% sick of my econobox, but getting 32-35mpg sure is nice when you're driving about 400 miles per week. If I could see 26-28 out of my stock A4 2.73 car with the same type of driving, I'd be happy.

I average 25mpg highway.
Best has been 26.5mpg.

2.73 gears

Not sure about city because I don't drive strictly city for a tank of gas.

See sig for mods. I too drive 74mi. a day (95% interstate) to work. I don't normally DD the camaro, but sometimes I'll DD for 2-3 wks straight before I park it again. I've NEVER gotten less than 20mpg. I set the tripmeter every fill-up and check it. My best was 25mpg before the tune. Since the tune my best is 23mpg.
I drive fast. I'll drive 70-75mph very gently for half a tank but then I can't take it anymore and will do retarded burnouts at lights and blast full-throttle to 110. I average 21mpg all the time. If I had the self control to baby it (I don't), it would no doubtedly get a little better. I usually only drive it to play with it, so I sacrifice 2-4mpg.

2.73 gear, Lid, LT's, ORY, LM1, and some free mods. Added an LS6 intake and P&P TB but didn't get an average with those before winter.

Best before bolts-ons was 27 mpg but it was about all highway.

Average with 60% highway and 40% city after bolt-ons the range is between 22 and 25 mpg with aggresive driving.

Plan on getting a tune the spring, we'll see if that helps with mileage at all.

3.23's
Full exhaust (LT's + Corsa)
Fairly aggressive driving style....can't help it I love the noise!!!

Average between 250-280 miles per tank daily driving to work and school.

Best I've achieved was 375.8 miles on one tank highway driving down from SC to FL. It shocked me....but I wasn't complaining.

I've got the same problem. I'm pretty confident if I could drive "normal" for a whole tank I could get back up to around 26-27mpg, but whats the fun in driving like that?

CAMAROZ28AQUINO

bone stock 98z w/ 2.73's i got 21mpg in stop and go traffic, no highway. Now with exhaust, gears and a stall i see around 15 city only and maybe around 18-20 mixed.
