An engine of a car needs lubricants or fuels and are most commonly known as Engine Oil, Motor Oil or Engine lubricant to produce horsepower. In engine, fuel (petrol or diesel) combustion takes place in order to produce power. They are lubricants which consist of oil complemented with various additives which is used to lubricate an engine. In addition to providing power for a vehicle to move, it also reduces friction as well as wear and tear between the moving parts in an engine. Engine Oil cools the engine as well as improves the binding and mechanical sealing. There are basically two types of car engine when classified on the basis of the types of fuel used, which are petrol engine and diesel engine. There are two types of Engine Oil : firstly, …show more content…
API classifications are different for petrol and diesel engines: for Spark ignition engines (petrol engines), listings start with 'S ' (SG, SH, SL, SM, etc.) and for Compression ignition engines (diesel engine), listings start with 'C ' (CF, CG, CH, etc.). 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

Mobil Delvac MX is best to use with heavy vehicles like, Safari when compared to Castrol GTD,GTX. Castrol, Mobil and Shell Helix are fully synthetic oil. Castrol Magnatec in Opel Astra, OpelCorsa and Maruti Suzuki Swift work best as they have petrol engine. Skoda India used Shell Helix Ultra 5W-40 in Laura and Superb, Castrol Magnatec 5W-40 or 5W-30 synthetic grade oil especially for Skoda Rapid Diesel Model. Vento works fine with Mobil 1 5W-50. Volkswagen works best with oil grade of SAE 40 or Castrol Magnatec 5W-40, keeping in mind India 's weather and temperature condition. For Mercedes-Benz car series Mobil 1 5W-50 or Mobil 1 10W-40 is preferred on the Indian roads. Castrol Power 1 Racingoil is specifically made for racing bikes only. Taking some of the customers review, Shell Advance has been given more preference for motorcycles like Hero CBZ Xtreme and Honda Stunner. MarutiSwift cars tends to work with grade 15W-40. Some Volkswagen and Skoda diesel and petrol cars, including Polo andFabia uses synthetic oil - mainly Shell Helix Ultra 5W-40. Chevrolet car owners give thumbs-up to Mobil 1 ESP 10W-40 and Audi owners generally couple their car 's engine with MOBIL 1 ESP FORMULA 5W-30 or with MOBIL 1 NEW LIFE 10W-40 for Sportback models. BMW 's engine are paired with MOBIL 1 ESP 10W-30. Mustang drivers are happy to use Mobil 1 5W-30 with their wheels. Castrol Magnatec SAE 10W-40 (semi-synthetic) is recommended for Honda City
