So a mechanic who is very expert in his field was suggesting on the other day that the oil i purchase from Honda dealership for my Honda city is not as good as the oil available in market of manufacturing companies. According to him the car company like Honda orders total parco to manufacture oil for them with Honda bottle won't be as good as total parco oil available in market as car manufacturers tend to save money on oil and same thing is done by total. Do you think its correct?
