Though car & motorcycle both can be passenger vehicles but there are a lot difference in these in Physical & technical condition. We all know about the physical difference between Car & Motorcycle, so let’s talk about technical difference. First of all, as there a lot of space in car so every segment of car engine is located in different places with enough distance.Here gear box,transmission, main engine which produce rotational power from fuel; all are in separate system. So have to use lubricants separately for every segments individually.Such for transmission have to use transmission oil,for gear box have to use automotive gear oil.And for engine have to use engine oil also.Even for cooling system in car have to use coolant.
On the other hand,in motorcycle gear,transmission & main engine are in a combine system.And for that have to use only one engine oil for motorcycle which works for engine,clutch, gear & power transmission and also for engine cooling.In most of the motorcycle no need to use lube oil filter but in case of car engine it is must.In case of RPM motorcycle has higher that car.And generally motorcycle fuel is Octane or petrol but Diesel or any kind of Gasoline fuel can be used in car engine.
