PART SYNTHETIC OIL

Does your car need a part 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 75,000 miles on the odometer, but that don't require a full synthetic.
