Petrol. Living in Minnesota.Hi Dave, Petrol or Diesel engine?
If it’s petrol it’ll probably be ok.
Diesel should be changed biannually and are easy to get to.
If you use Top Tier gas all the time, you shouldn’t need to replace the fuel filter any time soon. There’s no maintenance schedule from Mazda which means it’s the “life-time” filter. And the fuel filter on my 1998 Honda CR-V with 185K miles got replaced at 181K miles for the first time. The inside of the factory fuel filter looked as clean as the new one after 181K miles of service with mostly Top Tier gas.76K miles on my ‘15 CX-5 Touring model. Reliable auto shop where I trust them. Told me fuel filter should be ok. He would need to ‘drop’ a few things under the hood to get to it, but said fuel filters last a good while and I am ok to leave as-is.
Thoughts??
Good to know thanksIf you use Top Tier gas all the time, you shouldn’t need to replace the fuel filter any time soon.

There’re always 2 fuel filters and 2 fuel pumps in modern fuel system on the vehicles. Usually the smaller low pressure fuel pump and its filter right in front of it are build-in with fuel gauge sending unit submerged in the fuel tank. The bigger high pressure fuel pump and its canister-type filter usually are external and the high pressure fuel filter most often located in the engine bay. The canister-type high pressure fuel filter on my 1998 Honda CR-V mentioned in my previous post is located on the firewall.Do you need to replace fuel filter every two years?
I see a post on Reddit said Mazda require owners to replace their fuel filter every two years or 30K miles whichever come first. How come my dealership never said anything about fuel filter, I only have 10k on my cx-5 right now, but it is about 2 years by now. I am not sure should I go to...www.mazdas247.com
Fuel filter is just a strainer/sock in the tank.. there isn't anything under the hood.
If you do that you’ll have to pay additional $229.32 MSRP for the low pressure fuel pump. Might be better off just to get entire “fuel pump assembly” which includes fuel gauge sending unit and fuel pressure regulator (p/n: PE1A-13-35X for AWD and PE01-13-35X for FWD; #1 in parts schematic).EDIT: If I ever do go down this road of changing this I will be well over 100k miles and would probably change the in-tank fuel pump as well.
BTW, how is the oil seepage on your timing chain cover and / or rear crankshaft bearing seal (and oil pan?)?yrwei52: Thanks for info. This will be a long ways out but good PN to bookmark. Spark plugs next year or so will be next project... I'm currently near 64k miles on my '15 purchased summer of 2014.
