I usually change engine oil with motul brand full synthetic Recently the dealer recommended me to use ADNOC oil full synthetic what do you think ?
Look for anything with the API SN, SN Plus or SP marking on the bottle. The ADNOC Voyager Star Plus Eco 0W-20 meets SN rating and is probably the version we'd favor here in the USA if ADNOC sold their brands here. I couldn't tell you if it had any advantage over the MOTUL product- the way I see it, if it has earned the API badge for the standard applicable to the car, then it doesn't matter what brand it is. So get the cheapest one that earned the right rating.
