PEAK SYN PRO DIESEL 15W40 is a low SAPS (sulphur and phosphorous) product that incorporates the most advanced development in lubrication chemistry and high viscosity index semi synthetic base oils resulting in a high performance Diesel engine oil.

PEAK SYN PRO DIESEL 15W40 has been formulated specifically to meet the requirements of Australian and imported designed low emission engines including those engines which incorporate exhaust gas recycling (EGR) to provide fuel efficiency, high wear protection and long drain capability. EGR can add to deposits forming in the combustion chamber, and therefore the low sulphated ash content assists in maintaining engine cleanliness.

PEAK SYN PRO DIESEL 15W40 is recommended for high speed, turbo charged four stroke LPG and petrol engines, in particular all emission design engines. Designed to protect emission control systems, help comply with emission standards, reduce engine wear and control piston deposits and oil consumption.

PEAK SYN PRO DIESEL 15W40 is specially formulated to protect exhaust after treatment devices such as diesel particulate filters (DPFs). Fortified to reduce valve stem and guide wear normally associated with the dryness or lack of lubricity that is characteristic of an LPG fuel. Importantly, as LPG engines generally run hotter than a petrol engine. Possesses the oxidation resistance necessary to prolong lubricant life preventing oil thickening and combat the effect of acidic attack from nitrous oxides that damage soft metal bearing materials.
