Fully synthetic engine oil made with Shells patented PurePlus technology. Used in modern gasoline and diesel engines of vehicles (both with and without particulate filters).

Shell Helix Ultra ECT is based on GTL (Gas to liquid) base oils and uses Shells innovative emission control device compatible technology to protect exhaust after-treatment systems and catalytic converters in gasoline engines. Keeps diesel particulate filters (DPF) clean and protects them from needle deposits. Protects high-efficiency engines from efficiency-reducing deposits and wear, ensuring high engine efficiency. Reduces engine friction and helps save fuel and reduce exhaust emissions.
