Yesterday, I had my oil changed at the dealer and when checking out my service advisor reviewed the work performed. He wanted me to know that from now on, Volvo is requiring that Castrol Edge Professional V 0W-20 oil must be used when any oil service is completed for "All model year vehicles (2015-)". He provided me with a copy of Volvo's TIE, Technical Information Exchange, Ref No. US 34740 1.3 en-US, dated 1-27-20. It is "Updated to include all model year vehicles built using the 4 cylinder VEP engine". It also states "Volvo will not pay for any oil maintenance claims that are performed without using Castrol Edge Professional V 0W-20 oil" It also states, "The U.S. and Canadian markets will follow the extreme driving conditions recommendation".
