Bought a lightly used 2016 Acura RLX about 4 months ago and part of the certified pre-owned check list the dealer swapped the oil and upon inquiry I was told they put in Mobil 1 0w20. My first time ever with an 0w20 oil and I am really impressed with this oil. Last week was extremely cold here and we were in the negative degrees and the car fired up without hesitation and no chatter from the valve train at all in this extreme cold. No knocking, no ticking, no nothing. Very impressed with M1 0w20 so far!!
