Replying to: wackypawn (Nov 05, 2008 10:24 am) You have a lead foot but may not think so? hold gears too long? down shift too much? the gas you are using is trash? your car doesn't have sufficient time to warm up during the commute? you are in a hilly area? you have to hit many traffic lights? It's already cold where you are + hills + traffic lights? you brake too hard and have to accelerate more to get up to speed? you have a trunk full of cement? forgot to untie the dead Buck or Boar from your roof rack? Ah! You have a bicycle or kayak roof rack? you drive around with said bicycle, kayak, and dead wilflife on your roof rack through the snow, up hills, stopping at every traffic light and don't realize all four tires are punctured.

Replying to: gretsch6120 (Nov 05, 2008 12:53 pm) Don't forget another factor... ethanol. I'm taking about a 10% hit on mileage in both my vehicles now that ethanol is everywhere. Pretty much everyone I know is seeing this effect. Check the The Inconvenient Truth About Ethanol discussion.

Replying to: wackypawn (Nov 05, 2008 10:24 am) So what I may be doing wrong? Does it sound like I just got a lemon? Any suggestions or driving tips would be greatly appreciated!   Suggestion: for the next two weeks slow down by 10 miles and see what happens. I predict your fuel economy will miraculously improve!

Replying to: wackypawn (Nov 05, 2008 10:24 am) My manual 2.0 liter sedan gets about 28 mpg with similar driving and about the same number of miles (3000 miles in the six months I've had the car; I drive a mile to a transit station for work and most other driving is in town). When I was really having fun driving I was getting 22-25 mpg and was horrified. For some reason I thought it was better to have the AC on fresh air at first (in hot humid Georgia). Driving to conserve fuel and putting the AC on recirculate got me to 28 mpg, which is about what I expected, though I hoped for more than that. With a bigger engine and automatic like you have the mileage would be less.

Replying to: wackypawn (Nov 05, 2008 10:24 am) Thanks for the feedback. I'll slow down and will throw away the dead buck. If I'm not too lazy, I'll report in couple if weeks.   I use Costco gas in SoCal so if they are known for adding ethanol/crappy gas let me know. Replies to this message: sshpr (Mar 16, 2009 8:19 am)
#667 of 735 2.0 M3 auto mpg by damian1962 Dec 02, 2008 (6:32 am)
2.0 m3 auto with a combined mpg of 29, I have fun and I make sure not to go over 65 mph. I simply drive in a way where I avoid stop and go sequences. My M5 2.3 gives me a combined 24.5 mpg. You have to know what speed to apply during your routes. There are times when 65mph is no problem with no stops, but there are times when 50 mph is the velocity. When you find yourself passing and being passed your driving wrong, your suppose to catch up without braking harshly. You'll notice the cars that pass you get stuck ahead because there racing thinking they are going to get to a place faster by doing so, in a stop and go it's best to flow.
#668 of 735 Cold Air Intake by ylz Dec 11, 2008 (4:13 pm)
Hello all. Buying a 2009 Mazda 3 Hatch this month and I had some questions. I am thinking of buying a cold air intake for more power but my friend who owns a 2008 says I'm nuts. I have test driven this car a few times and I know it has power but what about the highway? I frequently drive over 80 and am I going to have trouble passing people, making two lane passes, etc...?? Do I need this intake? Also, does the intake really help that much? I have heard mixed reviews about it. And I can't seem to find one online for a 2009, I only see for 2008 models and below. It's the same engine and should fit, right? Thanks. Replies to this message: percussionist (Dec 11, 2008 5:22 pm)

Replying to: ylz (Dec 11, 2008 4:13 pm) Slow down and skip the air intake - you'll save gas by doing both! Why would you need to pass anyone on a two lane road (I assume you mean one lane in each direction) if you are travelling at 80 MPH?   PS - We may live in very different areas, but there is no place around here that it is legal to go anywhere near that fast.   All that being said, however, I don't think you should have any power problems trying to pass at highway speed with just about any car on the road today - they can all go over 80. The only time this ever becomes a problem is when the person you are trying to pass speeds up (which, surprisingly happens often). If that's the case, don't bother. It's not worth it to save three minutes on your trip.   Good luck - the Mazda 3 is a great car!
#670 of 735 First 5.5 weeks and 3,301 miles... by shipo Dec 26, 2008 (12:00 pm)
Car: 2009 Mazda3 i Touring Value Edition 5-Speed   Worst tank: 1,809-2,129 miles (319.9 net) -- 11.480 gallons -- 27.87 mpg  - - Notes: Includes lots of local driving and sub zero temperatures.   Best tank: 2,895-3,301 miles (406.1 net) -- 12.389 gallons -- 32.78 mpg  - - Notes: 85% highway, mostly on cruise control set at 70 mph, temperatures in the high thirties/low forties.   Overall: 3,301.4 miles -- 110.024 gallons -- 30.01 mpg   Given that the engine is still far from being broken in (from a fuel economy perspective), and given that the temperatures have often been well below freezing, I'm thinking that a 30 mpg overall average is pretty good for a car used for a daily commute to and from work.   Best regards, Shipo Replies to this message: ahightower (Dec 27, 2008 6:18 am) autonomous (Jan 02, 2009 2:19 pm)
#671 of 735 13 months, 18,000 miles by ahightower Dec 27, 2008 (6:18 am)
Replying to: shipo (Dec 26, 2008 12:00 pm) That is pretty good, Shipo, considering the conditions. At 3500 miles, I was averaging 31.25 mpg, but the weather was a lot more pleasant here, and I've managed to avoid the worst traffic.   Here's my info since Nov. 2007:   2008 Mazda3i Touring 5-speed   Worst tank: 245.7 mi., 8.806 gal., 27.90 mpg Best tank: 397.8 mi., 11.414 gal., 34.85 mpg   Overall: 18,126 mi., 576.574 gal., 31.44 mpg   Also just a daily commuter. Sometimes I beat traffic and cruise along at 60 mph the whole way, sometimes I sleep in and it takes an hour to go the 22 miles to the office. There have been no long highway trips at all. I'm pretty satisfied. Replies to this message: autonomous (Jan 02, 2009 2:19 pm)
