I agree that in your case it seems excessive, but service intervals are determined for the average use. You could service it annually, but be warned that if you did that and were to have a problem that resulted in a warranty claim you might be rejected because you haven't serviced it according to the book. I would service it according to Mazda's recommendation until the warranty runs out, and then consider moving to longer service intervals.
I don’t believe eight to 10 months between services, given the mileage you’re doing, would present a problem as long as you stick to a regular maintenance routine.
It’s an old car and you have to expect some wear and tear over what is now coming up for 20 years. Smoke on a cold start isn’t necessarily oil related; it is often condensation and nothing of concern. The oil leak is probably just a gasket that has hardened or split and needs replacing. If it is burning oil it could be due to wear in the valve guides or it could be worn piston rings or wear in the bores. If it’s not leaking a lot, just leaving a spot on the driveway, and it’s not using much oil I wouldn’t be too worried about it. The worst-case scenario would be that engine might need reconditioning.
There are a number of things you can do; it really depends on how much money you want to spend. You could start by increasing the tyre pressure by three or four psi above the recommended pressure and see if that is enough to do what you want. Beyond that you could fit sportier tyres, you could fit harder suspension bushes, lower the suspension, fit better shock absorbers, and heavier anti-roll bars. If you do want to modify the suspension I would suggest you consult a specialist such as Pedders or K-Mac.
The tyres have probably scalloped, which is a problem on the Mazda 3 and would explain why the noise has got worse. You could try the Michelin Pilot Sport 3, PS3, which is regarded as a quiet tyre.
I doubt the dealer’s advice is correct and have passed your problem on to Mazda for comment and follow up.
Check the fuel pressure to make sure it hasn’t dropped since you changed the filter. Perhaps put the old filter back on and observe what happens to the idle speed, fit another filter if the speed returns to normal.
The diesel and petrol engines in the current Mazda3 have timing chains.
Current analog radios won't work without some sort of interface. Pioneer make one called the Pure Highway that is mounted on the windscreen and receives the digital signal and puts out an analog signal.
