Hmmm, I've owned my 1994 MX3 GS (1.8L V6) (US) since it's birthday, and have never fallen below 25MPG, even when in rough city driving... I average around 26MPG on a weekly basis, and if I drive any distance at all on the highway, that average jumps to near 30-ish. On cross-country (1000 miles all highway) trips, it averages between 32MPG and 33MPG. It sounds to me like something may be out of whack with the poster's model. Also, the engines on this car in particular do NOT like having their intake or exhaust systems altered... nearly any modification (as simple as a high-flow air breather/filter) will DROP horsepower. So modified intake parts and exhaust parts as this poster listed, very well could be the source of the low MPG... there is a very specifically tuned flow-volume that the engine is designed for (a split low and high end powerband range that are optimized with the systems)... altering that flow significantly throws things out of whack, especially the timing and computer systems. It might sound better, but it won't work better. The best solution for more power is a new engine (the 2.5L Japan spec V6 (KZ-ZE or something like that, don't have it in front of me), which gives it a monstrous gain, with only VERY slight modification required to fit in the bay (why they never sold it with that engine is beyond me, that'd be a monster value pocket rocket). Anyhow enough rambling from me.

I have a mazda MX-3, 1993, automatic, 6 cylinder. Love the car, love the speed and love the look.

Right now going through hell because of it. In the 9 months that I've owned it, I had to fix it 5 times, little things, $50 here, $100 there. Now the worst fear of all came true. Transmission blew. Can't find an old part, rebuilding it is even more expensive. Everyone gives me 20,000 km waranty. Anyways I am looking at $2000 in repairs. So this cute little car has turned into a nightmare. As a student who has to pay for school, rent, books etc, I have to come up with almost $2000 to fix the transmission that has been fixed before, and from what I've seen, I'm not alone when it comes to these Mazdas.

Just bought new rear bearing in Scotland UK, cost £120.00 and it includes the hub.

My car has just passed 82,000 miles, still runs like a dream.

Slicked the engine and gear box, also the ignition system makes a big difference. Back droplinks are also expensive, they go quite often especially if you fit 17 inch wheels, better with 16 inch wheels, give a better ride, suspension is also good with these wheels.

See ya all,

I own a 1996 24v V6 and I have noticed that the plugs do foul up a bit, just put in one stage hotter and it's a dream. It also helped in the cold starts and was needed when I changed my exhaust and intake, and I haven't had a problem yet.
