The molecular particles in advanced chemically synthesized ester are extremely stable and bond securely at severely high operating temperature and enable exceptional flowability at winter ambient temperature. Hence, esters were used exclusively in military jet engines for many years. Our highly innovative chemists make use of the superior technology that has been widely applied in the aerospace lubrication, and even enhance them in the design of our signature fluids and oils for boundless applications. Our cutting-edge P-9 ESTER Technology was ultimately developed, achieving superiority on the excellent API Group Category V synthetic ester. This technology is geared on predetermined structural of the carboxylic acid and oxoacid, then undergo unique formidable bonding methods with specifically chosen alkyl groups and the complex esters. As in result, The P-9 ESTER helps to bond all of the ester compounds robustly to put up the peak lubricating performance, regardless of operating condition, environment, and temperature in your means of transport.

P-9 Technology brings out the maximum effectiveness and advantages of esters.

13% higher film strength than commonly used Group V ester base (1)

Polarity refers to the ability of the oil molecules to attract and bond with other molecular structures. P-9 Ester is designed to established unbreakable bond with polar structural and attach to metal robustly. Thence, FS1 motor oils demonstrate better lubrication performance when running at severely high-temperatures and elevated wear protection under extreme load conditions.

14% higher shear stability than commonly used* Group V ester base (2)

Shear stability refers to the property of the oil to resists the action of shear forces and viscosity loss due to related mechanical stressed and destruction. P-9 Ester is designed to help improved viscosity retention (without additional VI improvers) and minimize the possibility of oil polymers dilution (thinning). Thence, FS1 motor oils deliver optimum viscosity-temperature behavior at high and low working temperatures.

11% higher ageing resistance than commonly used* Group V ester base (3)

Ageing resistance refers to the ability to withstand external influences with minimal deterioration of oil and additive qualities. P-9 Ester is designed to enhance the stability of ageing to allow the most stable fluidity performance within the designated drain interval thence, FS1 & FS1 European Makers Formula support long drain interval (especially recommended by European manufacturers in recent years).

7% more hydrolytic stable (biodegradable) than commonly used Group V ester base (4)

Water content (contains bacteria and fungi) is by-product of the esterification process and it can break esters back into alcohol and acid compounds. P-9 Esterification process have been formidable in chemically block the hydrolysis pathway using P-9 branched carboxylic acids and unique fatty acids. Therefore, it maximizes the prevention of biological organism to cleave the ester bond and breaking the compounds into simpler components that can be easily metabolized.

The results of P-9 Esterification were examined using various laboratory methods in ASTM audited laboratory.

(1) Evaluation conduct using Increasing-temperature thermogravimetric (TG) analysis on the ester bond.
(2) Evaluation conduct on shear-stability index (SSI) using advanced ultrasonic shearing test method.
(3) Evaluation conduct in according to ASTM D2893, study on kinematic viscosity fluctuation to determine the rate of degradation.
(4) Evaluation on hydrolysis reaction to identified the rate of hydrolytic degradation, result was acquired on the 731th day.
