Engine oil Kendall or OEM Mazda

From my personal experience, I used to use Mobil 1 and Pennzoil Ultra Platinum oils, which are really high-quality oils. However, I did notice a big difference when I began using the OEM Mazda oil. I don't know what is so different about it, but my engine runs much more smoothly and very quietly. When I am at a stop light, I don't even feel the engine running, it's gotten that quiet, and I just hit over 100k miles.

I use Mazda Moly 0w-20 in our 2014 Skyactiv CX-5.

Remember that the rotary engine burns oil by design and does not particularly like eating synthetics. Expect to use old fashioned dino juice and change your oil every 3000 miles.

Although this is exact replacent, mazda OE still uses Mazda branded GF-5 which is exactly the same oil but branded Mazda....

Love these high molly low viscosity oils. Absolutely the best out there

Kendall GT1 10W30 - Volvo filter 1275810

Done every 5k miles by my local Volvo specialist because that's their default and I like it to be checked out frequently. It's the oil they use. 179k miles

I switched to Kendall GT-1 20w-50 high performance and I highly suggest it. You can get 12 quarts shipped to your door from Amazon at a good price.

They should be using 0W20 full synthetic oil (not synblend crap). Its not going to hurt running the 5W20 in it instead but next time mention it at write up. Mazda claims benefits such as better cold start protection and better efficiency among other things.

I use to use Castrol Syntec 5W40 (what the tig came with) and all I could get here. Last spring I opened my own shop and can get Kendall 5W40 Euro and started using that as it is 502 approved. I found it made the engine run smoother and quieter. My customers have noted the same.

If you want it quiet and smooth, run 10w-40. If you want best mpg or live in the cold 1/2 the year, run 5w-30. 10w-30 is a-ite in many cases. It'll burn less than 5w-30....generally.

For the record, this is NOT the exact replacement to Mazda 0W-20 GF-5 with Moly - Synthetic Engine Oil.

While this has high molybdenum, it's still a different formula from Mazda's own proprietary blend.
