Hello everyone,
I have a toyota 1.6X SE and it's driven 32K kilometers. I trusted toyota dealership and till this time they keep putting 5w-50 tanglon engine oil. I feel the car heavy as well as acceleration is not quite good as well as fuel efficiency. Can anyone expert recommend what I should do now ? Can I try to switch to 5w-30 now as that's recommended in manual as well. Toyota Indus maybe trained these people to put 5w-50 in new engines even that's not required. I just wanted Toyota genuine maintenance but I think their knowledge is limited or they don't read manual at all. I expected they must have followed best practices but now need recommendations.
