What oil is recommended for lexus gs300?
5w-30 is the norm. There’s always a lot of debate on the Mobil 1 / Castrol War but they are both very very good oils….. I used Castrol Syntec Blend in one Vehicle and Mobil 1 and drove both vehicles over 200k Miles and they were still running great. Just take good care of it do regular maintenance and then it doesn’t really matter what oil you are using…..
