I have got a new Avventura - Exotica Red. Till today it has run only 91 km. I am planning to go for a long drive from Kolkata to Bilaspur about 850 km. What should be my speed limit considering a new engine. Can I drive at 100 kmph? With my old petrol engine , i was advised not to go above 70 kmph till 250 km. Is there any rule with diesel engine? After what km will i get an efficient diesel consumption?
