PRO SPEC series is flagship model of Speed master engine oil. It is the Super multi engine oil that obtain special quality of almost perfect.
Especially , it is the engine oil that specialized durability and heat resistant in High temperature Base oil consists of polyol ester + Special highly viscous ester + highly viscous PAO.
hydraulic pressure reduction on High temperature and antioxidation by compounding to CA Salicylate-based cleaning agent(an action in high temperature)
Even in any period of consecultive in high temperature,it do not feel the heat sagging to maintain initial performance over a long period of time.
This is designed with an emphasis on Racing use, however it is possible to use in a normal replacement cycle even in the street.
As dissatisfaction point in a conventional racing oil, it will be pointed out to short term cycle(stability of initial performance)
And is a big problem also power-down due to the heat sagging in continuous ultra high temperature state .
PRO Spec series is evolving in order to solve this problem , we are confident the specs closer to the ideal.
We have evolved into a more higher level”Engine oil experience performance does not go down even in a continuours ultra-high temperature states” with maintain initial performance over a long period of time.
Normaly it is main composed of density raw material that will not be used for engine oil, it control hydraulic pressure reduction even at ultra-high temperature states Furthermore , since the racing oils which have enhanced oxidative stability at high temperatures of the washing based additive is a portion which has not been conventionally emphasized , durability was significantly improved We were greatly expanded the experience level of initial performance drastically.

Ester based material is synonymous with high performance engine oil that is used in many racing oils.
However some people say “Short term oil” “not suitable to long term”.
Some of the ester -based materials , fatty acids to be used is presumed to be because the extremely weak material is present to oxidation and It is leaving the extra acid without completely ester bond and On the structure , there is a weak binding moiety,etc.
On the other hand, from first launched,we stuck to using the ester material,Always has been achieved endure performance for use in harsh conditions by using the best of materials for that reason ,It was also on the available oil in the normal replacement cycle in the use of the street of rapid temperature change.

AS THE FLAGSHIP MODEL OF SPEED MASTER , WHICH REPEATS THE IMPROVEMENT TO COMPANY WITH ALL VARIOUS CONDITIONS OF ALL TYPE OF ENGINES , AND IT GAINS THE PROPERTIES WHICH IS ENDRESS CLOSE TO IDEAL . IT IS SUPERIOR MULTI GRADE OIL WHICH DECREASES THE FRICTION RESISTANCE AND PROTECTS THE OIL FILM UNDER THE HIGH TEMPERATURE GO IN THE HIGH DIMENSION TOGHTHER THE DESIGN IS PLACED THE EMPHASIS ON THE DURABILITY ESPECIALLY UNDER THE HIGH
TEMPERATURE . IT IS EXCELLENT IN THE STABILITY OF OIL TEMPERATURE AND OIL PRESSURE.
THE OIL FILM STRONGLY PROTECTS ENGINE AS WELL EVEN UNDER THE LONG TIME SEVERE OPERATING CONDITIONS . FURTHERMORE , AS THE CHARACTERISTIC OF SPEED MASTER , THE SPECIAL OIL WHICH IS PLUSED BY THE ENHANCEMENT OF POWER AND RESPONSE .
MINIMUM , AND ENHANCING THE COLD START . FURTHERMORE , IT POSSESSES AN AMAZING
STRONG OIL FILM BY THIS VISCOSITY . AN EXCELLENT PERFORMANCE IS SHOWN IN TIME ATTACK TO COMPETE FOR 0.01 SECONDS FROM NA TO TURBO . IT IS SUPERIOR SPECIAL OIL TO ENHANCE FUEL ECONOMY AS WELL .
In order to improve the torque at all speed range it is change compounding the base
To correspond to the further stringent conditions of Regulation of exhaust gas of car,
It is a new design of the oil that has a review of the additive component .
