TriboDyn TRI-EX Full Synthetic 15W40 Motor Oil - Quart Bottle

TriboDyn® TRI-EX Heavy Duty 15W-40 Full Synthetic Motor Oil stands as the premier choice for owners of high-performance diesel and gasoline engines, expertly engineered by tribologists in a USA-based ISO 9001 facility to deliver unmatched protection for turbo diesel systems with oil-fired injectors, low-emissions motors with EGR and DPF using ULSD or LSD fuel. This heavy duty 15W 40 diesel oil provides superior LSPI (low-speed pre-ignition) protection, keeps pistons clean, suspends soot, and extends drain intervals, while offering rust protection for flex-fuel E85 engines to combat corrosion. Engineered with the innovative “Treats the Metal, Not Just the Oil” technology, it bonds oil to metal surfaces to prevent dry starts, reduce friction, and enhance motor performance, boosting horsepower, improving fuel mileage, and extending equipment life with improved lubrication. This multi-use motor lube is ideal for trucks, off-road construction equipment, marine diesel, and powersports, meeting or exceeding API CK-4, CJ-4, ACEA E9, E7, E4, E2 service specifications. Available in 1-quart bottles.
