Penrite HPR Diesel 15 Engine Oil 15W-50 20 Litre
Penrite HPR Diesel 15 is a high performance semi synthetic 15W-50, non-friction modified engine oil featuring Penrite's Double Layer of engine wear protection. This oil incorporates Penrites Full Zinc additive package, creating a sacrificial layer on critical engine components to protect them from metal to metal contact and cold start wear. This oil also features Penrites Extra Ten technology, providing increased oil pressure and internal engine protection in high temperature climates and severe operating conditions. With a combination of increased dispersant levels and low shear viscosity modifiers, HPR Diesel 15 provides protection against viscosity loss, corrosion, oil oxidation and sludge formation resulting in a longer, healthier life for your engine. Suitable for use in modern multi-cam and multi-valve common rail and direction injection diesel engines. Also suitable as a mixed fleet oil in petrol, E10 and LPG vehicles and motorcycles with wet clutches. Not suitable for vehicles equipped with Diesel Particulate Filters (DPF) To find the oil type and viscosity suggested for your vehicle; either add your vehicle to My Garage or check with your manufacturer, vehicle user manual, your local mechanic or head in-store and talk to one of our friendly team.
