Supports LSPI (Low-Speed Pre-Ignition)
Developed as a modern version of HKS’s best-selling oil “HKS SUPER OIL” series. Recently, we have prescribed additives to prevent LSPI (Low-Speed Pre-Ignition) in downsizing turbo engines, which has become a problem in the automobile industry. Generally, LSPI is said to be more likely to occur with a combination of downsizing turbo engine + low viscosity oil, but with a tuned high compression / high boost direct-injection turbo engine, it occurs even with high viscosity oil under severe combustion conditions. The new “HKS SUPER Racing” was born as an engine oil compatible with high viscosity and LSPI, which is unprecedented in the world.

100% Synthetic Oil is used as the base oil
100% Synthetic Oil is used as the base oil that controls the basic performance of the oil. Also, like the conventional engine-specific oil, the viscosity is set and blended according to the engine specifications.

Q1.I’m in an NA car, does it make sense to use LSPI compatible oil?

A1.LSPI is unlikely to occur in NA vehicles, but the new oil standard clears the old standard, so you can use it with confidence. Even if it becomes LSPI compatible, another performance is not sacrificed, and the overall specifications are improved by using the latest formulation.
Super NA Racing can also be used for sports driving in downsizing turbo cars that are normally specified as 0W-20 and 0W-30.

Q2. Why is Super Rotary Racing not LSPI compliant?

A2. Since the rotary is required to have characteristics with less burning residue (low ash content), the amount of additive components is originally small. Since the rotary engine is not so high in compression ratio and boost pressure, it follows the proven conventional formulation.

Q3. What are the benefits of using 100% thin stick as the base oil?

A3. The basic physical strength of the oil itself is different. A strong oil film can be formed without relying on additives that deteriorate when exposed to high temperatures and high loads.
Additives are like energy drinks and their performance improves temporarily, but the basic physical strength of the base oil is important because the performance deteriorates over time.

Q4. Why was Super Boxer Racing set up on the 10W-40?

A4. It is an engine that tends to make a side knock sound of the piston when it is cold due to problems with short strokes, big bore, and aluminum block. If the viscosity when cold is too soft, the sound tends to be loud, so the hardness is set to an appropriate level.

Q5. I’m riding RB, but I’m worried that the successor model has become softer even though the conventional engine-specific (RB) oil was 15W-55.

A5. There is a standard for viscosity display, and the notation has been changed to comply with the standard. There is a wide range of viscosity indexes classified as 15W-50, and among them, it has a harder characteristic, so please use it with confidence.

Q6.The viscosity has changed with the new oil, is that okay?

A6. The oil delivered by HKS is the oil with strong multi-grade characteristics that is soft at low temperatures and hard at high temperatures. Low temperature is related to fuel efficiency and stability, and high temperature is related to oil film strength, but both are compatible at a high level, so you can use them with confidence.

What is LSPI?

• LSPI: Low-Speed ​​Pre-Ignition
• Especially in direct injection engines and tuned engines that often cool fuel, gasoline as fuel adheres to the cylinder as a liquid, diluting the oil on the wall surface and making it easier to flow.
  The temperature of the oil wound up by the high-speed reciprocating motion of the piston ring and the airflow in the cylinder rises due to the adiabatic compression of the air-fuel mixture accompanying the rise of the piston, and combustion starts without permission when the ignition temperature is exceeded. (Pre-ignition)
  This is an oil-derived LSPI.
• In a highly tuned engine, it may occur near the intercept due to the extremely high salary. This may be the cause of knocking that does not fit even if the ignition timing is delayed.

What happens when pre-ignition occurs?

• In the example shown, pre-ignition induces knocking. Knock damages pistons and plugs. Pre-ignition often involves severe knocking.

What is LSPI compatible oil?

• What kind of oil is the oil that makes it difficult to cause LSPI?
  It suffices to devise the formulation of additives to prevent ignition.
  This is LSPI compatible oil.
• The cause of LSPI is related to Ca (calcium) -based additives that are generally used for the cleaning action of oil, and this Ca causes early ignition like an ignition agent due to deterioration of oil. Become.
• Specifically, we have changed the calcium-based additive for cleaning and dispersing agents to a newly developed magnesium-based additive.
