Synthetic blend oil

Does your car need a synthetic blend engine oil? Somewhere between conventional and full synthetics, they’re a popular and economical choice.

When might you need synthetic blend oil?

What is part synthetic oil? Also known as Semi Synthetic or Synthetic Blend engine oil, these motor oils provide a balance between the economy offered by conventional oil and the superior performance of full synthetic oil.

 

Among the leading part synthetic oils you can choose between are Castrol® GTX® Ultraclean, which provides superior protection against the build-up of sludge, and Castrol® GTX® High Mileage, which is engineered for vehicles with over 120,000 KM on the odometer, but that don't require a full synthetic.

Castrol GTX Ultraclean

Sludge, varnish and carbon can build up in your engine, reducing engine life, power output and fuel economy. Castrol® GTX® ULTRACLEAN has a double-action formula that cleans away sludge and prevents new sludge from forming. It provides 45% better sludge protection than is demanded by tough industry standards.

Castrol GTX High Mileage

Castrol® GTX® High Mileage Motor Oil has been liquid engineered specifically for vehicles with more than 120,000 KM on the odometer. Not only does it protect against sludge, wear and burn-off, it features Phosphorous Replacement Technology to help protect your car's emission system from catalytic converter failure.
