Fully Synthetic Oil

Give your engine the ultimate protection with high-quality fully synthetic oil from Opie Oils. Fully synthetic engine oil consists of chemical compounds which are not originally present in crude oil but are artificially made. Engine oil that is fully synthetic generally provides superior mechanical, thermal and chemical properties than those found in traditional mineral oils, plus it comes with various other benefits such as extended oil drain intervals.
