They also include grades like SN, SM, SL and SJ for gasoline engines. A motorcycle oil uses the SF or SG standard.
There are also other standards for measuring the quality of engine oil such as International Lubricant Standardization and Approval Committee (ILSAC), etc.
A petrol engine requires a spark plug to ignite the fuel-air mixture in the cylinder. But a diesel engine doesn 't require a spark plug since the compression of the fuel-air mixture in the cylinder is so high that it generates enough temperature to ignite it. Since, diesel engine has to compress more; its parts (piston, connecting rod, crank shaft, flywheel etc) are heavier and stronger than petrol engine. Since, petrol engine parts are lighter; they can spin faster than diesel counterparts. Hence, a petrol engine revolution per minute is higher than diesels. As diesel engine parts (flywheel/crankshaft) are heavier, they can produce more torque than petrol engines. Since diesel parts are bulkier (stronger) and moves slower- they also wear slower than petrol parts. Stronger and heavier the …show more content…
