2013 CPO CX-5 2.0L 76k miles
Avg. Fuelly MPG = 29.6
Throttle response was getting a bit spongy/soft on 1st, 2nd and 3rd gear acceleration. Shift points were reving RPM's higher then normal where 3rd gear felt labored holding a higher rpm. Downshift slow to respond climbing hills. Overall shift points felt less crisp. Engine was starting to get "louder" in the front end especially on cold start. Car was feeling and sounding more like a Chevy.
Realizing this was way "off" from the really crisp enjoyable ride I have experienced for the last 50k miles, I decided to opt for the KISS approach and change all fluids at 75k and spark plugs. Short observation is it made a huge improvement. Car feels brand new. Here is a list of what I recommend at 75k:
Front and Rear Differential = (2) Bottles of Mazda Genuine Part Number 0000-77-SG1-QT | Lng Life Hyp Gear Oil Sg1 - (only took 1.5)
Spark Plugs = (4) Mazda Genuine Part Number PE5R-18-110 | Plug,Spark (funny story - ordered OEM and sent me NGK, they fixed it though)
Transaxle (ATF) drain and fill = (6) Bottles Mazda Genuine Part Number 0000-FZ-113E-01 | Atf Type-Fz (only took 5)
Transaxle (ATF) Filter = (1) Mazda Genuine Part Number FZ01-21-500 | Strainer,Oil
Parts cost = $250
ASE Labor Cost = $500
Now I can't recommend what service made the most difference, but I speculate that this is such a precisely tuned vehicle that a combined service really put this back to factory. I plan to do the same service at 150k.
I have been reading on here that gear oils are lifetime with some advice either way.... but I highly advise changing out these fluids if you enjoy better performance of the vehicle especially on the low end acceleration. YMMV
Plan to update this information if I notice a discernible MPG increase.
