Greetings,
I just bought a mazda5 and it has the L4 2.5 engine in it. The one previous owner seems to have all of the regular servicing done. He mentioned Coolant flush, oil changes with 0-20 every 7k miles. Filters are clean and recent.
What should I look at servicing on this motor? I plan on driving this for at least 5 years and I want to get the best fuel mileage I can get. I plan on replacing the plugs with NGK or Bosch iridium from rock auto. Seems like the serpentine belt is in good shape, I might just buy one because they are cheap to replace.
What is the transmission model number? I have read in the mazda 5 sub that this is the same transmission that was in Ford Focus. Transmission fluid looks somewhat clean, it’s translucent but dark, not black. So I would guess it has been changed before. I’ll look into changing that in the spring.
One minor problem I noticed is that there’s some kind of engine vibration when it’s in drive and you are stopped with foot on the brake. What exactly causes this problem? Clean MAF?
I used to have the 2.3 duratec in a ford ranger I had and it’s an easy motor to service. I did a lot of research and I bought this combo as they next year was the skyactiv motor. It got better fuel mileage but I wanted the reliability and simplicity of this old style motor. That being said I will switch from 0w20 to 5w20. I have never seen much of a difference in fuel mileage only in oil cost.
Thanks for the advice
