I have a 2014 CX-5 Touring front wheel drive with 52K miles. I am wondering if I need to clean the fuel injector systems or anything else? I have only done regular oil change, engine air filter change, cabin air filter change, wiper blades and new tires since I bought the car. No other maintenance so far.

Do I need to do anything? I have now had the car for 4 years an 9 months. What should I do if anything to keep car running in good condition and give gas mileage and performance. Not looking to spend money if I don't have to :-)

Thanks for advice and tips.

 

Doesn't hurt to run a bottle of injector cleaner through the system every now and then, but if you're using top tier fuel that is usually sufficient. Nothing else necessary or recommended by Mazda.

 

Thanks. What constitutes as top tier gas? Also, is there a way to know how dirty the system is? And whether a bottle of injector cleaner achieved anything at all?

 

Google is your friend and you'll find out all that you need to know about Top Tier gas.


Without taking stuff apart it's hard to tell if your fuel system is 'dirty' or not. Get a bottle of Techron and follow the instructions, cheap insurance.

 

You never should have to run fuel injector cleaner; all fuel, and I do mean ALL fuel sold in the U.S. and Canada has plenty of additives to keep fuel injectors clean for the life of the vehicle.

 

That's quite the blanket statement.

 

Many gas stations have notes on their pumps, or entrance doors indicating whether their fuel is top tier. It's a selling point. If you fuel up at one of the major brands, you are likely getting top tier. Google is your friend as well.
