Is Blue Shell HX7-Plus Engine Oil Fully Synthetic?
2 Answers
Blue Shell HX7-Plus engine oil is fully synthetic. Blue Shell is divided into two viscosity grades: 5W20 and 5W30. The advantages of Blue Shell HX7-Plus engine oil are that it performs better than mineral lubricants and offers high cost-effectiveness. It is suitable for vehicles with turbocharged engines or diesel engines. Blue Shell engine oil is manufactured using Shell's PurePlus technology, which provides benefits such as superior performance in viscosity stability, wear resistance, and low volatility for the base oil. It helps extend engine life, reduce maintenance costs and oil consumption, improve fuel economy, and better maintain engine cleanliness. Whether from a cleanliness or practical economic perspective, Blue Shell HX7-Plus engine oil has more advantages compared to conventional engine oils. As a product under Shell Helix, Blue Shell HX7-Plus engine oil, compared to more widely used traditional base oils, can help extend engine life by preventing wear during daily traffic conditions. It is also suitable for gasoline, diesel, and natural gas engines, as well as biodiesel and gasoline or ethanol blended fuels.
I see many people asking if the Blue Shell HX7 Plus is a full synthetic oil, and the answer is no. It's actually a semi-synthetic oil, processed with synthetic technology but mixed with some mineral components. I've been using it for several years, and it works well for regular family cars—not as expensive as full synthetic oils. The advantage of synthetic oil is long-lasting engine protection, such as less carbon buildup under high temperatures, but HX7 Plus is sufficient for daily driving. The key to choosing engine oil is checking the API or ACEA certification on the label. Most HX7 Plus oils meet SL or SN grades. Don’t cut corners with no-name oils, as they cause faster engine wear and shorter oil change intervals. Generally, changing it every 6,000–7,000 km is fine. Just sharing some small tips to help you avoid pitfalls.
