Mobil 1 0W-20 Quart (0.946Litre)


How does it help maximize engine efficiency?

Modern automobile gasoline engines have an efficiency of about 15%.

The remainder of the energy (about 85%) is unused and rejected as heat in the exhaust gases or consumed by the motor in he form of friction.

There are 4 key areas in an engine where energy loss occurs:

1.  The Valve Train
Energy loss occurs in the camshaft bearings and also in the contact area between the valve and lifter.

During warm-up, Mobil 1™ Advanced Fuel Economy flows faster because of its lower viscosity to minimize metal to metal contact to reduce friction and wear.

Note – many modern engines have roller lifters to reduce friction loss

2.  The Piston and Cylinder
Energy is lost at the piston liner interface during the combustion cycle and especially before and after the midstroke.

Mobil 1 Advanced Fuel Economy works to reduce friction at points of contact between the piston compression rings and cylinder walls.

3.  The Oil Pump
In the oil pump, energy loss occurs due to rotational energy consumed by pumping heavier viscosity oils (10W-30, 10W-40, 20W-50), particularly during warm-up.

During the warm up phase, the Mobil 1 fully synthetic formulation because of its lower viscosity flows more easily through the oil pump, requiring less energy to pump the oil to the critical engine parts.

4.  The Crankshaft
The main bearings and connecting rod bearings are two areas where friction abounds.


Mobil 1 Advanced Fuel Economy’s synthetic base stock composition ensures low traction (internal fluid friction) to further contribute to improved engine efficiency.
