    Is it just me, or does my 2014 Mazda3 like regular gas (87 oct) better than 89 or 91?

    During a 17 day vacation out west with my son, I was stunned to discover just how many western states have bad gasoline. Almost every car on the road today requires at least 87 octane gas. Some older cars can be damaged by running less than that. Newer cars WILL make less power on anything...

    Opinions on the Active Driving Display?

    I thought it was kind of cheesy at first, but I do like it now, especially with the nav directions appearing there. I don't have the tech package.

    New Summer 2014 Mazda3 Wheels On Order

    I love the wheels. I noticed a difference--the tires spin more easily now! I actually stopped stomping so hard on the gas from a stop because of this. It should reduce acceleration times a bit, and make the steering a bit more responsive. Grassroots Motorsports recently did tests with their...

    2015 Mazda3 Sedan & Hatch - 2.5 Liter "S" Model with Manual Transmission

    The fact is that modern, WELL-PROGRAMMED, automatic transmissions are far superior from every performance perspective. That's why all full-on race cars use them, and it's why many of the expensive sports car manufacturers now use them exclusively. The only reason to buy a manual transmission...

    2015 Mazda3 Sedan & Hatch - 2.5 Liter "S" Model with Manual Transmission

    I hate to say it, but I kind of feel the same way. I've always been a die hard manual transmission fan, but I really like the auto in my 2014 Mazda3s GT. Sport mode works quite well, and I always drive in Sport-Manual mode now, except when cruising on highways. My toy, my 2009 RX-8, is...

    Is it just me, or does my 2014 Mazda3 like regular gas (87 oct) better than 89 or 91?

    According to Road & Track, you should assume the other way around, most likely: http://www.roadandtrack.com/go/news/new-technology/premium-fuel-futures

    Is it just me, or does my 2014 Mazda3 like regular gas (87 oct) better than 89 or 91?

    Like I've pointed out several times on these forums, most modern cars will automatically advance engine timing on higher octane gasoline. The Ford Source Book for my 2012 Focus specifically stated that the car would make more power on higher octane gasoline, and the difference was quite...

    Is it just me, or does my 2014 Mazda3 like regular gas (87 oct) better than 89 or 91?

    I haven't noticed either of those things. I tried 93 octane for quite a while, noticed no difference in power, and bumped down to 89 octane. I don't notice any difference on any of them, 87, 89, or 93.

    Weight of OEM 18x7" wheels?

    It was noticeable after I had the new wheels installed. I had to stop stomping on the gas at traffic lights, as it just resulted in absurd amounts of wheel spin. I'm (pleasantly) surprised at just how much wheel spin the traction control program will allow on this car, at least when you hammer...

    Have you filled with anything higher than regular gas?

    It is actually not a "fact." It depends on the gasoline, as stated in the Road & Track article. I have found no evidence in anything I've read that indicates that using premium in a modern car that requires 87 octane is bad for the engine. Road & Tack state that they use Shell 91 in *all* of...

    Have you filled with anything higher than regular gas?

    Pretty sure that is not true with recent cars. http://www.roadandtrack.com/go/news/...?click=main_sr I have also been using 89 octane gas (usually Shell). I didn't notice the improvement in performance with my 3 that I did with my 2012 Focus on 93 octane gas, so I backed it down. I stuck...

    Weight of OEM 18x7" wheels?

    Thanks, cj10. I think it was Tire Rack that listed my OZ Racing wheels at 17 lbs., each. Mine were all individually weighed by the inspector. They vary from a low of 16.733 lbs. (the tag I have in front of me at my office) to just barely under 17 lbs. That's a serious weight drop!

    Autocross day with a 3 S Touring coming up

    Does the S Touring have the Sport mode? I think it does. If so, I would definitely recommend Sport-Manual mode. Throttle response is quicker in Sport mode, making the car more responsive to throttle inputs.

    Wow, that's an amazing build! I always liked the Probe, especially the gorgeous second generation one. Now you've given it the drive layout it deserved in the first place.

    Lowering Kit and Rims for 2014 Mazda3

    I'm very excited. The first time I emailed Racing Beat, Jim Langer told me they were waiting out the market for aftermarket parts for the 2014 3. I asked about their exhaust and mentioned I was still interested in springs, and he replied that springs and anti-roll bars are in production right...

    Lowering Kit and Rims for 2014 Mazda3

    Yes, "doing it right" means different things to different people. There are people who would argue that doing it right means going for Ohlins-quality coilovers or not doing it at all. Many aftermarket dampers are poorly matched to each other, and few are individually dyno-tested, so you can...

    a prayer for the Sport mode

    Yeah, when I was using normal D mode around town, if I changed to Sport mode, it was to have fun. Now I just use Sport-Manual mode to get it to be more like the real manual transmission cars that I've always loved and owned. You can still drive reasonably and fuel-efficiently in Sport-Manual...

    Polarized glasses and Mazda 3 dash don't play well together

    LCD technology uses polarization to create the display. This is a fundamental issue with most, if not all, LCD displays.
