2. Motor oil - Wikipedia

   en.wikipedia.org/wiki/Motor_oil

   An oil pump, a vane or gear pump powered by the engine, pumps the oil throughout the engine, including the oil filter. Oil filters can be a full flow or bypass type. In the crankcase of a vehicle engine, motor oil lubricates rotating or sliding surfaces between the crankshaft journal bearings (main bearings and big-end bearings) and rods ...

3. SAE J300 - Wikipedia

   en.wikipedia.org/wiki/SAE_J300

   The oil fails the test at a particular temperature if the oil is too viscous. The grade of the oil is that associated with the coldest temperature at which the oil passes the test. For example, if an oil passes at the specified temperatures for 10W and 5W, but fails at the 0W temperature, the oil is grade 5W. It cannot be labeled 0W or 10W.

4. Two-stroke oil - Wikipedia

   en.wikipedia.org/wiki/Two-stroke_oil

   The oil is dyed blue to make it easier to recognize in the gasoline. It appears black in this bottle because it is not diluted. Two-stroke oil (also referred to as two-cycle oil, 2-cycle oil, 2T oil, or 2-stroke oil) is a special type of motor oil intended for use in crankcase compression two-stroke engines, typical of small gasoline-powered ...

5. Lycoming IO-720 - Wikipedia

   en.wikipedia.org/wiki/Lycoming_IO-720

   The Lycoming IO-720 engine is a large displacement, horizontally opposed, eight-cylinder aircraft engine featuring four cylinders per side, manufactured by Lycoming Engines. [ 1 ] There is no carbureted version of the engine, which would have been designated O-720 and therefore the base model is the IO-720.

6. Nissan L engine - Wikipedia

   en.wikipedia.org/wiki/Nissan_L_engine

   However, in case of a conversion of a gas powered 720 to diesel, it will be much easier to use a LD20 because it fits on the original gearbox and engine mounts.) The N/A version produced 65 PS (48 kW) at 4600 rpm and 12.5 kg⋅m (123 N⋅m; 90 lb⋅ft) of torque at 2400 rpm, later 67 PS (49 kW) and 13 kg⋅m (127 N⋅m; 94 lb⋅ft) of torque.

7. Gear oil - Wikipedia

   en.wikipedia.org/wiki/Gear_oil

   For example, most modern gearboxes require a GL-4 oil, and separate differentials (where fitted) require a GL-5 oil. While they take the same form, the viscosity grades for gear oils are on a different scale than the viscosity grades for an engine oil. The viscometrics for gear oils are standardized in SAE J306.
