While some synthetic motor oil use hydrocarbon (PAO) as their base material, Organic based ester (base stock) for its motor oil inherents high quality characteristics has proven to be the highest quality base material for synthetic oil used even by aeroplanes.
One of the organic ester based synthetic oil is Chemlube www.chemlube.com.my. Chemlube synthetic oil remains committed to the use of organic ester although costs are about 40% more expensive than PAO or hydrocarbon synthetic oil.
Conventional 100% Synthetic super-multigrade lubricant (5W40, 5W50, 10W60...) use VII (Viscosity index improver) to boost their viscosity. These viscosity additive tend to loose efficiency and shear when submitted to extreme conditions. As motor oil use ester for its base material, it benefit from the natural viscosity of synthetic ester thus they need very little of such additives or none.
Esters are very stable at extremely high temperatures and are used almost exclusively in jet engines.
Superior benefits of organic ester are:
Natural Affinity to stay on metal surfaces providing a thin protective film to eliminate dry start-up engine wear which means easier morning starts and smoother engine operations.
Very High Viscosity Index indicate a low viscosity change. By employing Ester as the base for synthetic oil, it changes the conventional concept of synthetic oil. Ester are polar molecules that have the ability to electro-chemically bond with metals, so as to maintain a continuous lubricant film at high or low temperature (the element found in oil additive or as aditive in engine oil). This in turn provided a better resistance to thinning at high temperatures and thickening at low temperature.
Outstanding Film Strength so it takes a lot longer for the oil to drain completely off the bearings and into your oil sump. This prolongs engine life and increase engine efficiency.
Strong Detergent Characteristic - inhibits rust and corrosion but minimizes spark plug fouling and carbon, gum and sludge deposits. Ester itself is a natural detergent, it adheres naturally to motor parts which dissolves and suspending harmful sludge, varnish and carbon deposits which keep engines and lubrication ports cleaner and in top performing shape.
