With construction season in full swing, now’s the time to showcase the heavy-duty protection of Guardol XT®. This full synthetic diesel engine oil is fortified with Liquid Titanium® and built for the most demanding jobs. Phillips 66® Guardol XT® Full Synthetic Diesel Engine Oil delivers premium performance for 4-stroke diesel engines operating under extreme conditions. It meets API CK-4 standards for modern low-emission engines and is backward compatible for older models. Engineered for compatibility with advanced exhaust systems like diesel particulate filters (DPF), diesel oxidation catalysts (DOC) and selective catalytic reduction (SCR), it provides exceptional protection and cleaner performance. Its full-synthetic formula also ensures excellent low-temperature properties for superior starts and performance in harsh winter climates.
