Changed oil for the first time on my 2014 3i GT 2.0L at 2,500 miles today:
1. Safety raise car to allow access to underside.
2. Remove access panel by removing two 8mm (or phillips) hex bolts and two clips. (The clips have center part that you can use a small standard screw driver to gently pry down then you can remove the clips-see pics.)
3. Remove oil drain plug with 8mm hex wrench or hex socket.
4. After oil is completely drained replace drain plug after installing a new crush washer (my car did not have one from the factory- $1.39 from my Mazda dealer).
5. Remove oil filter. The filter is vertical beside the drain plug. It is best to use one of those filter wrenches that fit over the end of the filter and that you use a 3/8" ratchet to turn (see pics).
6. Apply a small film of clean oil to the seal on the new filter, fill it with new oil and install it. Do not use a wrench, just tighten snug by hand.
7. Add aprox. 4.4 Qts of new 0W-20 full synthetic oil. (owners manual says 4.4Qts and that put it to the top of dip stick).
8. Start the car and allow to run while checking underneath car for any leaks.
9. Turn car off, wait at least 10 minutes then check oil level to confirm it is full.
10. Replace oil change access panel under car.
11. Record oil change in your records. (remember to keep your receipts for parts to ensure Mazda will honor the warranty in case you ever have a problem with the engine.)
