Choosing the Right Oil

There are four main categories of engine oil: Synthetic, high-mileage, conventional and diesel. Synthetic oils were developed most recently, offering higher quality at a premium price.

When your engine deserves the very best, trust synthetic. Synthetic oil helps to prolong your engine life, performs better at all temperatures and requires less frequent oil changes. That means more money in your pocket.

Castrol Syntec
Castrol Edge with SYNTEC Technology

For years, you’ve depended on the power of Castrol SYNTEC to outperform conventional motor oils. Now, we’ve reformulated SYNTEC to outperform even itself:

  • In extreme tests, Castrol EDGE with SYNTEC Power Technology maintained maximum horsepower 30% longer than Castrol SYNTEC

Mobil 1 Advanced Fuel Economy
Mobil 1 Advanced Fuel Economy

Mobil 1 Advanced Fuel Economy, available in a 0W-20 and 0W-30 viscosity, provides faster lubrication and less viscous drag than higher viscosity oils. It offers the best fuel economy in the Mobil 1 line.

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 the form of friction.

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

  • The Valve Train, energy loss occurs in the camshaft bearings a 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.
  • 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.
  • 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.
  • 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.
