Ive followed oils , brands , grades etc for decades and seen many changes . As well heard many people suggest that changing the grade is good in a CX5 N/A for example ...from the current 0W-20 to a 5W-30 / which we see recomended in the turbo 2.5 and 2.5n/a in countries outside the US.
This is in my opinion a major decision to make and thus should be supported by facts that are scientific and obviously dont void the warranty. Ive read some that make the change say because , "my engine is much quieter" , or "dont use 0W-20 in the NA because is a predicate of " CAFE " regulations and is to thin to protect the engine properly " others cite why other countries get 5W-30 recomended on what appears to be the exact same vehicle .
So whats best ? I personally have an N/A 2.5 - 2023 and its uses 0W-20 in the US- Im sticking with that and have many reasons why. I looked for a good video which contains up to date scientific information on multi-grade oils and has tested data why they have reached their conclusions, and recomendations. Also they have a direct comparison to the difference between 0W-20 and 5W-30.
I choose this video for these reasons , and because they use a current 6.2 liter C8-N/A Corvette engine with ...get this ...Cylinder Deactivation !!! A close engine tech wise to the Mazda 2.5 N/A but obviously 4 cylinders shy . Its a good sign GMs top sports car has CD in its NA as a testament to its fundamental reliability and usefullness in fuel savings ..even on a 495bhp performance engine !
Please feel free to comment and interpret the findings and/or add why you use a specific grade oil either recomended or not.
