SYNFLEET MX products are a range of premium full synthetic diesel engine oils meeting the lubrication requirements of most modern high horsepower heavy duty diesel engines including those with advanced exhaust after-treatment systems such as EGR, SCR and DPF. SYNFLEET MX utilises the diesel additive technology to protect the engine and emissions systems operating under the most severe conditions including multi trailer and arduous off-road applications.

SYNFLEET MX has been developed to satisfy the increasing demands for extended service intervals when supported by routine oil analysis. The inherent high temperature stability of SYNFLEET MX products enables this oil to provide a level of protection not normally available with mineral or synthetic blend diesel engine oils. With full synthetic 5W-40 and 15W-40 viscosity grades there is a SYNFLEET MX product to protect your engine whether it is operating at -30°C or at over 50°C.
