0W-20

If your vehicle requires a 0W-20 viscosity engine oil Castrol offers options that meet the needs of drivers and vehicle manufacturers.

0W-20

CHOOSING THE RIGHT 0W-20 OIL FOR YOUR ENGINE

0W-20 motor oil is liquid engineered to flow as easily as a 0 Weight oil in winter temperatures, yet behave like 20 Weight oil once the engine has achieved its full operating temperature. This ensures that even in cold climates, oil will start to flow through engine oil ways immediately, providing lubrication to critical engine parts.

 

It's a common misconception that the 'W' in viscosity descriptions stands for Weight. In fact, it stands for Winter. In the case of synthetic 0W-20 oil, this means that it flows as easily as a 0 Weight oil in Winter temperatures, but is as thick and viscous as a 20 Weight oil once normal engine temperature has been reached.

Castrol Magnatec Stop-Start 0W-20

Castrol MAGNATEC STOP-START combines DUALOCK molecules with our most efficient, fully synthetic base oils to dramatically reduce wear by 50%* and save up to 60L** of fuel a year in congested driving, thus ensuring non-stop protection from every start.

*Tested versus the sequence IV A API SN wear limit.  Tested versus the CEC OM646LA ACEA wear limits. 
**Compared to an industry reference 15W-40 oil as tested in EUDC (for highway), EPA NYCC (for cities), and Castrol Ultra-idle cycle (for congestion). Assumptions: Annual mileage of 12000 km, representative split of driving (60% on highway, 30% in cities, 10% in congestion). Actual results under road conditions may vary according to vehicle type, driving conditions and style.
